The system configuration information is used for configuring the corresponding relation between each flow chain and the situation information of each satellite to be processed and the parameters of the target component in each flow chain; determining the configuration of each flow chain corresponding to the situation information of each satellite to be processed and the parameters of a target component in each flow chain; the configuration of the flow chain specifically includes which target components are configured and the order of the target components, the target components being any one or combination of a first component of the data receiving module, a second component of the data processing module, and a third component of the data forwarding module.

The method provides stronger data processing capability for satellite situation display and decision making, so that a user can better utilize data resources of a multi-satellite network, and more accurate and real-time monitoring and decision making support are realized.
In some embodiments, the system management module is further configured to register and generate each of the target components included in each of the flow chains based on the plurality of system configuration information, and construct an order relationship between each of the target components.
Specifically, the system management module initializes all target components included in each flow chain based on the plurality of system configuration information, namely registers and generates each target component included in each flow chain, and constructs an order relation among each target component, namely injects dependency attribute of each target component, so as to complete binding among the target components. The method comprises the steps of determining which first components, which second components and which third components are sequentially used for carrying out related processing on received original satellite data in a flow chain corresponding to situation data of a certain satellite to be processed, and then sending the processed original satellite data to a matched downstream application for display.
In some embodiments, the data receiving module is further configured to:
selecting situation information of each satellite to be processed for receiving different data sources through a first component used for selecting the data sources in each flow chain; the selection conditions of the different data sources comprise satellite identification, load quantity, downloading mode and time delay;
And checking the integrity, the legality and the correctness of the standard situation data through a first component used for data checking in each flow chain.
Specifically, the data receiving module not only can convert received situation information of each satellite to be processed into a unified data structure, but also can be used for: and receiving situation information data from different satellites and loads, and transmitting the situation information data to a data processing module after operations such as data source selection, data receiving buffering, data encapsulation, data verification and the like.
Fig. 2 is a schematic structural diagram of a data receiving module according to an embodiment of the present invention, and as shown in fig. 2, the data receiving module may include the following components:
2.1 first component for data Source selection (data Source selection component)
The data source selecting component is used for selecting and configuring a data source to be received, so that the data quantity is reduced, and the performance loss caused by the processing operation of unnecessary data is avoided; the data sources that need to be received are typically determined by the display requirements of the downstream application for the situation data.
The conditions for data source selection include different satellites, different payloads, different download modes, different delays, source indications indicating whether the data source is an original or an analog data source, etc.
Data source selection can be implemented in two categories:
one type: the satellite ground station receives signals of different satellites, the signals are classified to different channels by the satellite ground station according to different data sources for transmission, and at the moment, the first component for selecting the data sources can receive situation data of the specified data sources only by configuring the specified channels;
and (2) a second class: after receiving signals of different satellites, the satellite ground station does not divide channels according to data sources, generally selects satellite data meeting specified data source selection conditions through one or more data identifiers in the signals of the different satellites, and transmits the satellite data to a subsequent processing component. Thus, portions of satellite data that do not meet the data source selection criteria will be discarded, reducing unnecessary data processing, store and forward operations.
2.2 first component for data reception (data receiver)
The data receiver component is mainly responsible for receiving and buffering situation information data, and serves as an intermediate layer for data reception, receives and enqueues the original data from different satellites, so as to ensure stable reception and transmission of the data. The data receiver component temporarily stores the received data by using a buffer area, ensures stable receiving and processing of the data, and avoids the problem of data loss caused by mismatching of the capability of receiving and processing the data. The data receiver component typically uses a separate thread to separate data reception from other processing modules, avoiding blocking and delaying the operation of the overall system. Meanwhile, the data receiver component can be provided with a certain buffer management mechanism to control the buffer size, the data storage mode and the data access sequence.
2.3 first Assembly for data encapsulation (data encapsulation Assembly)
The data encapsulation component is located behind the data receiver and is responsible for parsing the different situational information data and encapsulating it into a system defined unified data structure or object.
Firstly, the data encapsulation component has the capability of resolving different data formats, including binary format, text format, JSON format, XML format and the like, and converts the data formats into a system predefined unified data structure for processing by subsequent components or modules, wherein the unified data structure comprises, but is not limited to, source codes, engineering values, units, value ranges, package identifiers, time of the star, device identifiers, links, data sources and the like.
The data packaging component then converts the situation information data into a unified data structure and packages into system-defined data objects, such as mapping the raw data to fields, attributes or methods of the unified data structure, and performing type conversion, unit conversion, etc.
Finally, the data package component is further provided with an appropriate error handling mechanism, which can handle abnormal situations possibly occurring in the analysis process, such as analysis errors, incomplete data, and the like, record error information, mark invalid data, and recover and report if possible.
2.4 first component for data verification (data verification component)
The data verification component is mainly responsible for verifying the integrity, the legality and the correctness of the packaged situation information data so as to ensure the quality and the reliability of the data. The verified data is sent to the data processing module for subsequent processing operations.
For integrity verification, the continuity and integrity of the data may be verified by information such as the length of the data, frame count, etc., including checking whether there are missing, duplicate, or inconsistent portions of the data. For example, verifying whether the data is received in the expected order and ensuring that no packets are lost.
For validity verification, whether the situation information data meets the validity requirement is checked according to preset specifications and constraint conditions. This may be achieved by using conditional statements, scope checks, regular expressions, etc. For example, whether the parameter value is within the expected range is verified, whether the unit is correct, etc.
And for correctness checking, the accuracy and correctness of the situation information data are verified by comparing the expected value or the known model.

Fig. 3 is a schematic structural diagram of a data processing module according to an embodiment of the present invention, where, as shown in fig. 3, the data processing module includes:
3.1 second component for data screening (data screening component)
The data screening component is a key component in the data processing module and has the function of screening the data according to various conditions, such as parameter subscription screening, star time screening, outlier screening and the like, so as to select the data meeting specific requirements for subsequent processing. At the same time, the data screening component allows control of the opening and closing of each screening function, allowing multiple screening conditions to be combined for more accurate screening of the desired data. The flexibility and configurability of the data screening component enable the system to conduct customized data screening according to different application scenes and requirements, and the processing efficiency of the system is improved.
The data screening component functions are exemplified as follows:
1) Parameter subscription, the user sets the parameter to be subscribed through the downstream application according to the self requirement and the requirement of the application scene. The user may define parameter subscription rules including the parameter name, data type, sampling frequency, etc. of the subscription, which are used to specify the specific conditions and requirements of the subscription parameters. And supporting dynamically updating parameter subscription rules, i.e. the user can modify the parameter subscription rules according to the change of the requirement, including adding new subscriptions, deleting existing subscriptions or adjusting the parameters of the existing subscriptions. And the screened subscription parameters are transmitted to the next component for subsequent processing.
2) And (3) satellite-time filtering, namely, a satellite-time filtering rule predefined by a user, and screening the data when the data enter the satellite to obtain the data meeting the requirements of the satellite-time filtering rule. The ephemeris filter rules include a specific time range, a time interval, ephemeris data, etc. These rules are used to specify the star time requirements required by the data processing module. The star time filtering rule can check whether the data accords with the star time rule by comparing the time stamp of the data with the ephemeris data, and if the time stamp of the data is in rebound or discontinuous condition, the star time filtering component can screen out the data marked as not conforming to the star time rule. Thereby ensuring sequence and consistency at star time.
3) The outlier filtering rule may be a threshold range of user input obtained through a visual interface of the downstream application according to the outlier filtering rule defined by the user, and the outlier filtering rule is configured for the second component in the data processing module through system configuration information determined by the system management module. The data determined to be outliers includes outliers, which are typically data points that have significant deviations from other data points, possibly due to measurement errors, data transmission errors, or other reasons, and outliers, which are typically data points that have significant differences from the overall distribution of the data set. The outlier rejection component performs outlier detection and identification based on the data characteristics using suitable outlier detection algorithms, such as statistical methods, threshold range detection, clustering, and the like. The outlier rejection component may reject outliers or outliers according to a predefined rejection policy. The culling strategy may be a simple deletion or marking of outliers, or may use interpolation, substitution values, or other methods to fill in or correct outliers. After eliminating the abnormal value, the second component for outlier filtering transmits the processed data to the next component for subsequent processing.
3.2 second component for data fusion (data fusion component)
The data fusion component is a key component in the data processing module, and has the function of processing situation information data representing the same physical quantity of the same satellite under different data sources, such as alignment, combination and the like, so as to generate a group of more complete and accurate data sets and provide more comprehensive data support for subsequent situation display.
The data fusion component functions are exemplified as follows:
1) Alignment of data: the data fusion component can align data from different data sources that characterize the same physical quantity of the same satellite, ensuring that the data at the same time stamp or time period can be combined into one valid piece of data. The data alignment function calibrates the different data source data according to the configuration rules so that they correspond to the same time standard point or time period on the time axis.
Such as a preset time stamp of a specified data source as a reference, and a time range in which alignment is allowed, are expressed as follows: t s -t|≤Δt；
Wherein t is s A time stamp representing satellite data from a preset designated data source (reference); t is a time stamp of satellite data from other data sources; Δt is the time range in which alignment is allowed. When the difference between the time stamp of the satellite data from the other data sources and the time stamp of the satellite data from the reference is within the range of events that allow alignment, then it is determined that the satellite data of these different data sources belong to the same period of data.
In addition, the time stamp correction can be performed on the aligned data, and the time stamp of the data of other data sources which are already aligned with the reference data source is modified into the time stamp corresponding to the data of the reference data source. At the same time, the data alignment function may correct the time stamp of the data according to a predefined delay or time offset, which is applicable to those cases where the time stamp is offset due to transmission delay or other factors, ensuring that the data is aligned correctly on the time axis.
2) Data merging
The data merging is a key function in the data merging component, is responsible for merging and conflict resolution of situation information data under different data sources, and provides more accurate data support for situation display. Specifically, situation information data from different data sources or data converted by calculation processing may have a plurality of values of the same physical quantity used for representing the same satellite, in the process of data merging, the data merging component firstly corrects abnormal data, firstly identifies and processes possible abnormal values, outliers and error values, corrects according to predefined rules and algorithms, and corrects the abnormal data. When there is a conflict or inconsistency in the data from the different data sources, the conflict resolution policies configured by the configuration management component in the system management module are reused, such as selecting values of the priority data sources, weighted averaging, or applying other rules to resolve the conflict. The merged data is transferred to subsequent components after ensuring consistency of data format and structure, providing a high quality data base for subsequent data processing.
3.3 second component for parameter conversion (parameter conversion component)
The parameter conversion component is a second component in the data processing module and has the following main functions: collecting and recording parameters, converting and calculating and aggregating and sampling.
The following are the functions of the parameter conversion component:
data aggregation: the parameter conversion component can filter and aggregate situation information data, and combine a set of consecutive data points with repeated values or minimal differences into one value to reduce the amount and complexity of the data. The continuous data discrimination, the time window range, the difference discrimination, the aggregation processing algorithm and the like can be customized in the configuration management component, and components with different processing logics are registered in the component management component. The aggregation processing comprises average value aggregation, maximum value aggregation, minimum value aggregation and the like, and the algorithms can be selected according to actual requirements and data types and conduct aggregation processing on the data within a certain time window.
And (3) data sampling: the sampling function is similar to aggregation, but differs. Sampling is the selection of partial data points from the data based on certain rules and policies to reduce the amount and complexity of the data while preserving the representativeness of the data as much as possible. The sampling rate, the time interval, the event triggering rule, the sampling method and the like can be customized in the configuration management module, and components of different processing logics are registered in the flow management module. The sampling rate can be dynamically adjusted according to the calculation capability, the storage capacity and the real-time requirement of the system so as to ensure the balance and the performance of the system. Sampling methods include time sampling, frame by frame sampling, event triggered sampling, etc., and selecting an appropriate sampling method can make the sampled data more representative.
Collecting and recording: the parameter conversion component is responsible for collecting various situation information data required by conversion from different data sources, and integrating multiple data used for representing the same satellite to form a comprehensive parameter set supporting conversion calculation. For example, the satellite ground station provides the transformation of the attitude angle of the same satellite in different coordinate systems, and the pv value of the load in a certain coordinate system and the pitch angle, the roll angle and the yaw angle in the coordinate system are required to be collected, and the collected information is integrated to obtain a complete data record. The collected parameter data is stored in a storage medium (such as a memory, a database, a file system, etc.) for subsequent conversion and calculation.
Conversion and calculation: in order to relieve the calculation pressure of the display end, the conversion component can convert and calculate parameters according to the system configuration information determined by the system management component, including numerical calculation, coordinate system conversion, unit conversion, data smoothing or other data processing technologies, so as to meet specific application requirements or analysis requirements. The parameter conversion component may modify the parameter data according to a predefined calibration algorithm or calibration rule to correct for possible deviations.
3.4 second component for data storage (data storage component)
The data storage component is a component for carrying out persistence on the data processed upstream, is convenient for data access, analysis and backtracking, and provides support for situation playback functions. The data storage component functions and features are as follows:
data persistence: the data storage component is responsible for persistent storage of processed data, can ensure that the data is still available after the system is shut down or restarted, and can store the data for a long time so as to meet the requirements of data retention and archiving. When the data is stored, a label is established to record various information, including a data source, a satellite time, a receiving station, a link type, a plan number, a circle number and the like, and the label information is customized according to playback requirements. Meanwhile, to ensure efficiency, the storage can be performed by adopting a separate thread.
Data security: the stored data is ensured to have good safety and reliability, and mechanisms such as data backup, redundant storage, data recovery and the like can be adopted to prevent the data from being lost or damaged and ensure the integrity and usability of the data.
And (3) data retrieval: the method can provide an efficient data retrieval function, enable a user to quickly access stored data, support various query modes such as filtering according to time ranges, keywords and conditions, and the like, so as to meet different data retrieval requirements.
And (3) data management: the method can conveniently carry out data management, including data storage structure, index management, data partition and the like, and can divide, organize and manage the data according to the characteristics and the use requirements of the data.
In some embodiments, the data forwarding module is further configured to:
compressing the situation data to be displayed according to a data compression strategy configured in the system configuration information by a third component used for data encapsulation and compression in each flow chain;
distributing the situation data to be displayed after compression processing to the downstream application according to a preset data distribution strategy through a third component used for data distribution in each flow chain; the preset data distribution strategy is a component part of a plurality of system configuration information determined by the system management module based on the processing capacity of the downstream application and the display requirement of the downstream application on situation information;
and monitoring the connection state between the flow chain and the downstream application through a third component for connection management, and determining whether to trigger an abnormal connection processing mechanism or not based on the connection state.
Specifically, the data forwarding module not only can encapsulate the situation information of each satellite to be processed according to the protocol type and the transmission mode supported by downstream application, but also can perform the processes of data caching, encapsulation and compression, transmission, distribution, connection management and the like.
The data forwarding module is the end of the whole processing flow and is responsible for packaging and sending the processed data to be forwarded to the service application, in particular to the situation display end. Depending on the differences in transmission technologies and protocols supported by the downstream application, the data forwarding module interacts with the downstream application in different implementations, including but not limited to socket communications, message queues, file system interactions, etc. In fact, due to the difference of interaction modes with the downstream, different forwarding assemblies can be registered in assembly management to realize different transmission logics, and in flow management, a proper forwarding module is selected for a corresponding processing flow to carry out reliable, efficient and safe data transmission.
Fig. 4 is a schematic structural diagram of a data forwarding module according to an embodiment of the present invention, as shown in fig. 4, including: and a third component for data caching, encapsulation and compression, transmission, distribution and connection management.
4.1 third component for data caching (data caching component)
The method is used for temporarily storing the data to be transmitted so as to cope with the condition of network connection interruption or transmission delay, and after the data transmission is recovered, the transmission is recovered from the buffer memory, thereby ensuring the integrity and the reliability of the data, improving the stability of the system, reducing the possibility of data loss and ensuring the continuity of the data transmission.
4.2 third component for data encapsulation and compression (data encapsulation and compression component)
And the data to be transmitted is packaged according to the protocol type and the transmission mode supported by the downstream application, the packaging format comprises a data main body and metadata information such as a time stamp, a data version number and the like, and the format processing working pressure of a display end can be reduced by adopting a unified output format, so that more energy is put on the scene display.
The compression process is carried out according to the defined compression strategy, so that the size of transmission data is reduced, the network transmission load is reduced, the data transmission efficiency is improved, bandwidth resources are saved, the data transmission time is shortened, and the effect is obvious especially in a large-data-volume transmission scene. The data compression policy may be configured in a system management module to manage component selection.
4.3 third component for data Transmission (data Transmission component)
In the system, the service scene of the data forwarding module is used for providing data for client driving situation display, the capability of supporting one-to-many transmission is required, and good transmission instantaneity and connection continuity are required. Meanwhile, because the transmission data volume is large, the performance requirement is high, the WebSocket connection is kept for a long time, the spending of frequently establishing and disconnecting the connection is avoided, and the burden of a server is reduced. In summary, the system employs Websocket communication based on netty implementation.
4.4 third component for data distribution (data distribution component)
And according to the characteristics and processing capacity of the data receiving end, different data distribution strategies are formulated. For example, broadcast, unicast, multicast, etc. modes may be selected for data transmission. According to different application scenes and equipment requirements, the data transmission mode is flexibly controlled, and the data transmission efficiency and adaptability are improved to the greatest extent.
4.5 third component for connection management (connection management component)
Is responsible for managing the connection with the downstream application and monitoring the connection status. The connection between the connection management component and the downstream application can be represented as a connection URI, the connection URI comprises a data source type, a client identifier, a channel number and the like, when a new downstream application is connected with the system, the connection needs to be registered, and a session is identified by distributing a unique ID according to information in the URI, so that the subsequent management and maintenance are convenient. The connection status is continuously monitored, and when a downstream application actively disconnects or disconnects due to network problems, corresponding resource release and connection removal operations are required. When a connection exception is encountered, such as a network surge or connection timeout, an exception handling mechanism should be provided, such as trigger reconnection or error handling logic.
Further, in order to detect the health status of the connection, a heartbeat packet may be periodically sent to the downstream application through a heartbeat mechanism, and whether the connection is still valid may be determined according to the reply condition of the heartbeat packet. If a large number of concurrent connections need to be handled, a pool of connections can be used to optimize resource utilization, create some connections in advance in the pool of connections, and allocate the connections when needed, reducing the overhead of frequently creating and destroying connections.
The actual data forwarding module may be adjusted and expanded according to application requirements and technical requirements, and the above examples are only references of common components, and detailed design is needed according to actual development and application scenes in specific cases.
In some embodiments, the flow chain is an asynchronous responsibility chain designed by adopting a responsibility chain design mode, that is, after any component in the flow chain does not need to complete the same task, the next task is processed, and each component may forward the result of processing task a to the next component and then continue to process the data of the next task B. The throughput rate and the processing efficiency are improved, each component is provided with a corresponding queue to receive the processing result of the last component, and asynchronous processing operation is realized through a multithreading or asynchronous framework mode. After each component node processes the data, the processing result is transferred to the next component node, and the execution of the next component is triggered until all the processing work is completed. By adopting the design mode of an asynchronous responsibility chain, the tasks of the data processing module are executed asynchronously, the throughput and the processing efficiency are improved, the system resources are fully utilized, the task waiting time is reduced, and the execution speed of the whole data processing flow is also accelerated by concurrently processing a plurality of tasks.
In some embodiments, the system management module includes a flow management component, a configuration management component, and a component management component;
the flow management component is used for configuring the corresponding relation between each flow chain and the situation information of each satellite to be processed, and the corresponding relation is used as first system configuration information;
the configuration management component is used for configuring all functional parameters of the target components included in the flow chain as second system configuration information;
the component management component is configured to register and generate each target component included in each flow chain based on the first system configuration information and the second system configuration information, and construct an order relationship between each target component.
Specifically, as shown in fig. 5, the processing flow of the system management module includes:
s01, defining a flow chain of situation information data processing in a flow management component, wherein the flow chain comprises functional components and positions and sequences thereof;
s02, setting or using default parameters for relevant configuration information of each registered functional component by configuration management, and supporting dynamic updating of component configuration parameters when a flow runs;
s03, registering all components contained in the components and connecting the components according to flow chain configuration information defined by flow management and functional component parameter information configured in the configuration management by the component management, and injecting the configuration;
S04, generating a data processing flow chain, and starting data processing and circulation.
In some embodiments, the system management module includes a flow management component for:
configuring the corresponding relation between each flow chain and situation information of each satellite to be processed;
and adjusting a plurality of target components included in each flow chain.
Specifically, the system management module comprises a flow management component, a configuration management component and a component management component; the flow management component is responsible for defining a processing flow chain of situation information data. Specifically, the user is allowed to customize the functional components used in the data receiving, processing and forwarding modules and specify the location and order of the functional components in the flow chain. The functional components are a first component of the data receiving module, a second component of the data processing module and a third component of the data forwarding module.
The following one flow management component is provided with a functional example:
and (3) flow configuration: when the processing flow is configured, the processing flow can be realized by enabling a user to drag and connect different functional components through a graphical user interface, and the processing flow can also be specified in a configuration file mode. In either case, the final system configuration information includes the flow chain ID, the flow chain containing component, the position of the component in the flow chain, the satellite/payload set that the flow chain is responsible for handling, and other elements. The user can allocate different process chains for different satellites/loads according to the needs, and can also allocate satellite load data with the same processing steps to the same process chain.
And (3) flow adjustment: and allowing the user to return to the flow management interface at any time when the system is running, and adjusting and optimizing the flow. Each functional component initializes a separate processing queue and pointer for it at registration. For the connection between the components, the pointer pointing of the component is defined only according to the system configuration information, specifically, the pointer pointing of the component is pointed to the next component in the flow chain according to the system configuration information, and each component is only responsible for taking out and processing elements in the queue and then putting the elements into the next component queue, so that the sequential circulation of data in the processing flow chain can be ensured. The matching of the queue and the pointer can enable a user to conveniently and flexibly adjust the position of the component in the flow chain by only providing an interface for modifying the pointing direction of the component pointer.
Configuration information persistence: and the configured data processing flow chain information is persisted, such as to a database, a file system and the like, so that the trouble of reconfiguration when the system is restarted is avoided.
The process starts and stops: the method mainly comprises the steps of registering, starting and stopping the processing flow according to the provided system configuration information. Flow registration and initiation essentially calls components in the component management flow configuration, and flow stoppage essentially calls components management to destroy components registered in the flow chain. Because the core logic implemented by the components is to continuously receive input data and output results after processing, each component remains operational after instantiation until destroyed.
Through the flow management component, a user can flexibly configure a data processing flow according to task scenes, so that personalized customization requirements of the user are met, and the situation information processing system can adapt to various different application scenes and processing requirements.
In some embodiments, the system management module further comprises a configuration management component for:
configuring various parameters of a plurality of target components included in each flow chain;
updating various parameters of a plurality of target components included in each flow chain;
managing different versions of the plurality of system configuration information;
system configuration information is imported and exported.
Specifically, the system management module comprises a flow management component, a configuration management component and a component management component; the configuration management component is responsible for parameter setting and customizing of each functional component, and allows configuration parameters and policies to be dynamically updated. In the implementation, each component has own configuration class, configuration information is recorded, and the Spring container automatically injects the dependent component into the target component after the component is instantiated. When the configuration is modified, the configuration class is only needed to be taken from the container for modification. An example of the functionality of one configuration management component is as follows:
Component parameter setting: a related parameter is set for each functional component. These parameters may include initialization parameters, runtime configuration, switches for a particular behavior, etc. Appropriate parameter values may be set according to the function and requirements of the component to adjust the behavior and performance of the component.
Parameter type and validation: the component configuration function should support different types of parameters, such as integers, floating point numbers, character strings, etc., and perform validity verification on the parameters. When the user inputs parameters, the system should ensure the correctness and legality of the parameters, and avoid the system error caused by illegal parameters.
Parameter default values: for certain parameters, the system may provide default values so that when no particular parameter is set, the component configuration may be performed using preset default values. Thus, the configuration process can be simplified, and the configuration work of a user can be reduced.
Dynamic parameter updating: the component configuration function should support dynamically updating parameters of the component at system runtime. The parameter configuration can be modified during the running process of the system without restarting the system, so that the system can respond to the requirements of different configurations in real time.
Component state monitoring: providing status monitoring functionality for the component allows a user to view the current configuration and parameter values of the component, as well as the operational status and performance metrics of the component, and the like.
Parameter version management: the configuration function can support saving parameter configurations of different versions, allow a user to manage the parameter configurations in version, facilitate switching different configuration schemes when needed, or rollback to a previous configuration state. It is understood that the parameter information of the history configuration, as well as the parameter information of the current configuration, may be switched between the parameter information of the history configuration and the parameter information of the current configuration.
Parameter import and export: the configuration function should support the import and export functions of parameters, allowing the user to save the parameter configuration into the file or import the parameter configuration from the file, facilitating batch processing and multiplexing of the configuration.
Through the component configuration function, a user can flexibly configure parameters of each functional component in the system according to actual demands, so that personalized customization and optimization of the components are realized, and the requirements of different service scenes are met. The function enables the system to have better flexibility, expandability and adaptability, and provides better user experience and service for users.
The component management component of the system management module is responsible for registration, dependency injection and life cycle management of each functional component. The IoC container of Spring and the dependency injection mechanism make the management and coordination of components very simple, and the AOP feature also provides more flexibility and maintainability for component management. Through a Spring dynamic loading mechanism, components can be dynamically adjusted according to the actual demands of the system, so that the system has better flexibility and expandability. Therefore, based on the Spring framework, the functions of the component management component realized by utilizing the factory design mode and the reflection agent technology are as follows:
Component registration and instantiation: component registration is responsible for registering and instantiating selected components in the flow configuration information. The system can package various or general or special functions, release the functions in the form of components, and the user only needs to specify the component ID in the process configuration, and the components can be instantiated in a reflection mode when the process is initialized. In particular, the component registration and instantiation can be given to the Spring container, and the component registration can be realized by configuring XML files, notes and other modes. After the components are registered, the Spring container will instantiate the components as needed according to the configuration information. The instantiation process is controlled by the Spring container and is performed when the Spring application is started. In the instantiation process, the Spring container instantiates components using techniques such as reflection and handles dependencies between components. If there is a dependency relationship between components, such as configuration of functional component dependencies, the Spring container automatically performs dependency injection, and the dependent components are injected into the target component.
Component lifecycle management: lifecycle management refers to the management of the various stages of instantiating, attribute assignment, initializing, using, and destroying components during the running of an application. In the Spring container, the life cycle of the component is automatically managed by the Spring container, and a developer can intervene and customize the life cycle of the component through a specific callback method. It should be noted that, the configuration parameters and policies required by the attribute assignment stage component are performed in an injection-dependent manner through configuration management, and the resource release operation can be performed in the destruction stage by calling a destruction callback method.
