Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The data hot updating method provided by the embodiment of the invention can be applied to a data hot updating system shown in figure 1. Specifically, the data hot updating method is applied to a data hot updating system, the data hot updating system comprises a data management system and a micro service as shown in fig. 1, and the data management system is communicated with the micro service through a network and is used for realizing data processing of an application program and storing relevant configuration information. The micro service refers to a small independent service end which communicates through a well-defined interface, and is easier to expand and faster to develop than a large service end. And the data management system represents the management system of the data shared by the micro-services. The data management system may be implemented as a stand-alone server or as a cluster of servers.
Medical cloud (Medical cloud) refers to the fact that a Medical health service cloud platform is created by combining Medical technology on the basis of new technologies such as cloud computing, mobile technology, multimedia, 4G communication, big data, internet of things and the like, and Medical resources are shared and Medical scope is enlarged. Because the cloud computing technology is applied to combination, the medical cloud improves the efficiency of medical institutions, and residents can conveniently seek medical advice. In the application of the medical cloud, a plurality of small independent service ends, namely the micro service is connected with the medical cloud to realize medical data sharing, and the independence of the micro service is ensured, for example, different appointment registration and electronic medical records of each hospital can be connected with the medical cloud to obtain shared data, and on the other hand, the independence of different systems of each hospital can be ensured. Therefore, in one embodiment, as shown in fig. 2, a data hot update method is provided, and the method is applied to the data hot update system in fig. 1, where the data management system includes the following steps:
S10: after the target data is acquired, the target data is stored in a system database, and the corresponding relation between the unique identifier of the target data and the micro-service using the target data is configured.
After the data management system acquires the target data input by the user, the target data is stored in a system database of the data management system, and a unique identifier of the target data is set according to user input or system automatic configuration. Then, according to the user input or the direct acquisition of the target data used on the micro services, the corresponding relation between the unique identifier and the micro services is set.
The method for acquiring the target data by the data management system comprises the steps of manually inputting the target data on a configuration interface provided by the data management system by a user, directly using a text or a file in a corresponding format by the user to import the target data into a database management system, and the like. The manner in which the unique identifier of the target data is configured includes, but is not limited to, the user customizing the unique identifier of the input target data at the time of configuring the interface or importing the data, being automatically generated by the data management system, etc. The method for configuring the corresponding relation between the unique identifier and the micro-service comprises, but is not limited to, manually designating the relation between the unique identifier and the micro-service on a configuration interface of the data management system by a user, directly acquiring the use relation between the micro-service and the target data by the data management system through interfaces and the like.
The data management system will store the target data, the unique identifier of the target data, and the relationship between the unique identifier and the microservice in a system database. In addition, each tag data may be used by multiple services, i.e., a unique identifier allows configuration of one or more micro-services.
For example, in an application program displayed on a vehicle, configuration data of a main page menu is stored as target data in a system database of a data management system. Generating a data file according to the configuration data of the main page menu and generating a unique identifier of the configuration data of the page menu according to the specified format in the data file. Then the data file is imported into the system database of the data management system from the configuration interface of the data management system, then the data management system displays the configuration data of the page menu stored in the current system database, the unique identifier of the configuration data of the page menu and all micro services using the system database in parallel, the unique identifier and the micro service name are modified on the configuration interface of the data management system according to the requirement by a user, and the unique identifier and the micro services are configured.
S20: and judging whether the change of the target data is acquired or not.
After the storage of the target data and the configuration of the correspondence between the unique identifier of the target data and the micro service are completed, the data management system needs to determine whether the stored target data has been changed. If the target data is changed, the flow advances to step S30.
In step S20 of this embodiment, the method for determining whether the target data is changed includes, but is not limited to, triggering the determination when the data management system monitors that the target data of the system database is changed, and triggering the determination when the user changes the target data from the configuration interface of the data management system.
S30: when the change of the target data is obtained, a data change notification carrying the unique identifier is sent to the micro service, so that the micro service inquires corresponding target data from a system database of the data management system according to the unique identifier as update data, and the cached data of the micro service is updated according to the update data.
When the data management system determines that the target data is changed, it is necessary to send notifications to all corresponding micro services of the target data configured in step S10, where each notification carries a unique identifier of the target data that is currently changed. The manner of sending the data change notification includes, but is not limited to, sending a link containing a unique identifier, invoking a notification method thereof via a micro-service interface, and the like.
For example, an organization structure manages an application, and the data management system originally stores primary department data in each organization in the application, where the primary department data is used on three micro services, and the three micro services are respectively a user service, an authentication service and a user role service, so the structure of storing the target data in the data management system is schematically as follows:
in the above data structure, data represents target data, id represents a unique identifier of the target data, relation represents three micro services corresponding to the first-level department data, userService represents user services, authenticationservice represents authentication service, userRoleService represents user role service. After the data management system acquires the data and changes, according to three micro services stored in a relation field in a system database of the data management system, sending notifications with ids to the three micro services respectively, namely, sending notifications with ids of'd 95e7e11b9cc47d7b33c254150a73a 46' to the user service, the authentication service and the user role service respectively, so that the three services acquire target data, namely, notification of changing the primary department data, and updating data caches of the three services according to the ids.
It should be noted that, in this embodiment, after the data management system acquires the target data, the target data is stored in the system database, and the unique identifier of the target data and the micro service using the target data are configured. The configuration defines the relation between different micro services and target data, so that when the subsequent target data is changed, the corresponding micro service needing to be refreshed can be rapidly found out according to the unique identifier and the configuration relation, and the efficiency of data hot update is effectively improved. And then, when the data management system acquires the change of the target data, sending a data change notification carrying the unique identifier to the micro service so that the micro service updates the data cached by the micro service, so that the micro service does not need to restart in a large area, and the data update can be completed only by acquiring the target data again by the corresponding micro service which receives the notification and carrying out cache refreshing, thereby ensuring the user experience.
In one embodiment, before step S30, immediately before sending the notification of the data change carrying the unique identifier to the micro service, the method for hot updating data further includes the following steps:
S41: and constructing a notification function method, and transmitting the unique identifier as a transmission parameter to the notification method, so that the notification method inquires out the corresponding micro-service according to the unique identifier, and constructing a data change notification carrying the unique identifier corresponding to the micro-service.
Before the data management system sends the data change notification, the data management system needs to construct a notification function method, wherein the notification function method needs a unique identifier of target data as a parameter, and then a micro-service corresponding to the target data is queried in a system database according to the unique identifier, and meanwhile, the data change notification carrying the unique identifier is constructed, so that in a subsequent step, the data change notification carrying the unique identifier is sent to the micro-service corresponding to the target data queried in the system database.
For example, in the example of step S30, a notification with id "d95e7e11b9cc47d7b33c254150a73a46" needs to be sent to the user service, the authentication service and the user role service to notify the three micro-service primary departments that the data has been changed, before this, the data management system needs to construct a notification function method, which is referred to as id, and this method is shown as follows:
public void notice(String id){
String noticeUrl＝‘http://xxxx/notice/’+id；
String microservices＝findService(id)；
…
return sendNotice(noticeUrl,microservices)；
}
As shown in the above-mentioned schematic notification function method, after obtaining the parameter unique identifier id, the method constructs a change notification link, where the notify link carries an id, and queries micro services corresponding to the id through the id and a system database query method findService, and according to the query result, the value of the micro services is userService, authorizeService, userRoleService, that is, three micro services are queried: user services, authentication services, and user role services. Finally, the notification function method sequentially sends data change notification notecirl to the three micro services.
In this embodiment, when sending the data change notification, a notification function method is constructed, and the method encapsulates the processing procedure from the unique identifier to sending the data change notification, and encapsulates the processing procedure to form a modularized function method for overall information processing, so that overall program logic is clearer. The encapsulated notification function method is beneficial to code reuse, and in addition, the security of the code is improved due to the encapsulation of the notification sending process.
In one embodiment, in step S10, the correspondence between the unique identifier of the target data and the micro service using the target data is configured, which specifically includes the following steps:
S11: and providing a visual configuration interface, and acquiring a unique identifier of the target data, the name of the micro service and the target data, which are set on the configuration interface by a user.
S12: and acquiring a corresponding relation between the unique identifier and the name of the micro service configured on the configuration interface by the user.
The data management system provides a visual configuration interface, allows a user to input target data on the configuration interface, and the input mode comprises, but is not limited to, the configuration interface provides an input box for the user to input the target data, and the configuration interface provides an import function for the user to import data files. After the data management system acquires the target data, the configuration interface provides an input box for a user to input a unique identifier corresponding to the target data, and all micro services using the data in the system database are listed. The user can modify the name of the micro-service in the configuration interface and change the corresponding relation between the target data and the micro-service.
If the unique identifier acquired by the data management system is empty, the original unique identifier of the target data is reserved, and the unique identifier is not changed. If the unique identifier is not set originally for the target data, when the data management system acquires the empty unique identifier, a random number or character string is designated as the unique identifier of the target data by the data management system. The unique identifier includes, but is not limited to, a random number, a random string, etc.
In addition, when the data management system acquires the target data, the unique identifier and the micro-service name which are input by the user on the configuration management interface, the data management system performs validity verification on the content input by the user. The validity verification includes, but is not limited to, unique verification of a unique identifier, filtering of illegal character strings, inhibition of cross-site scripting attack, and the like.
It should be noted that, the data management system in this embodiment provides a visual configuration interface, which is more beneficial to the user and developer to enter and configure the target data, improves the overall operation experience, and has good visual effect and operability.
In one embodiment, as shown in fig. 3, a data hot update method is provided, and the method is applied to the data hot update system in fig. 1, for example, where the micro service includes the following steps:
s50: and acquiring a unique identifier of target data configured by a data management system and a corresponding relation between the identifier and the micro service.
According to the unique identifier of the target data configured by the data management system and the corresponding relation between the unique identifier and the micro service, the micro service establishes the corresponding relation between the micro service and the target data used by the micro service. In the subsequent steps, the micro-service receives the corresponding data change notification conveniently.
S60: when the target data is changed, after a data change notification carrying a unique identifier sent by a data management system is obtained, inquiring corresponding target data from a system database of the data management system according to the unique identifier to serve as update data.
After receiving the data change notification sent by the data management system, the micro service queries corresponding target data in a system database of the data management system according to the unique identifier carried by the data change notification, and takes the target data as update data. The manner of receiving the data change notification includes, but is not limited to, receiving notification call information of the data management system from an open interface of the micro service, monitoring a notification message sent by the data management system by the micro service, and the like.
S70: and updating the data cached by the micro service according to the updating data.
And the micro service updates the cached data of the micro service according to the updated data after taking the queried target data as the updated data. The method for updating the data of the micro service cache includes, but is not limited to, the method for updating the cache after the micro service performs structure change on the acquired updated data, the method for updating all data of the micro service cache after the micro service receives the data change notification, and the like.
In the process of updating the data by the micro service according to the notification, because the method configures the corresponding relation between the micro service and the target data, when the target data is changed, the designated micro service is queried only through the unique identifier, and then the designated micro service cache is updated, the process does not need to refresh the cache data of all the micro services, the updating range is accurately controlled, other micro services which do not use the target data do not need to be subjected to redundant updating, and the abnormal errors of the micro service caused by frequent cache refreshing are effectively prevented.
In one embodiment, as shown in fig. 4, in step S60, the corresponding target data is queried from the system database of the data management system according to the unique identifier as update data, which specifically includes the following steps:
s61: and constructing a data change function method corresponding to each target data.
S62: and inquiring the corresponding data change function method according to the unique identifier.
S63: and executing the data change function method so that the micro service queries the target data corresponding to the unique identifier in a system database of the data management system, and takes the corresponding target data as update data.
In one embodiment, the microserver declares a snoop function method to the data management system that listens for data change notifications sent by the data management system. When the data management system sends out a data change notification of target data used by the micro service, the monitoring function method learns that the target data is changed through a unique identifier in the data change notification. After the monitoring function method acquires that the target data is changed, the data changing function method of the target data is queried according to the unique identifier. And if the corresponding data changing method is inquired, executing the data changing function method.
The unique identifier is used as an entry and is transferred to a data change function method. The functions of the data change function method include, but are not limited to, querying corresponding target data according to the unique identifier, processing the target data to conform to a data format required by the micro service, performing an action of updating data of the micro service cache with the target data as update data, and the like.
In one embodiment, the data change function method is an open method, allowing the micro-service developer to customize the data change function method.
It should be noted that, in this embodiment, the micro service declares an internal listener, that is, a listening function method, and the listener makes the data management system have a corresponding attribute to store the unique identifier when the unique identifier is imported, so that the subsequent data change function method uses the unique identifier. In addition, in the embodiment, a data change function method is opened to an open person, and the open person is allowed to customize the method, so that the method is more in line with the fact that in the actual development process, the developer needs to perform different processing on target data according to the use and requirement conditions of different micro services, and then the processed data is cached. The whole data hot update process is smoother and more reasonable.
In one embodiment, as shown in fig. 5, in step S62, the method for changing the function according to the data corresponding to the unique identifier query specifically includes the following steps:
s621: and querying the data change function method corresponding to the unique identifier.
S622: and if the data change function method corresponding to the unique identifier is found, executing the corresponding data change function method.
S623: if the data change function method corresponding to the unique identifier cannot be found, the updating action is terminated.
In one embodiment, all the data change function methods are open to the micro-service developer, allowing the developer to customize the data change function methods according to different functional requirements. As such, there are methods of altering the function of data where the developer does not define some unique identifiers. Therefore, in steps S621 to S623, the present embodiment judges and processes the case where the data change function method corresponding to the unique identifier does not exist.
After the monitoring function method of the micro service receives the unique identifier, the data corresponding to the unique identifier is queried for changing the function method, and if the corresponding data changing function method cannot be queried, the updating action is terminated. And if the corresponding data change function method is inquired, executing the inquired data change function method.
It should be noted that, since the data change function mentioned in steps S61-S63 is open to the developer for customization, there may be a case where the open person does not customize the function. Therefore, in this embodiment, fault tolerance is performed on the situation, so that the whole data hot update process has better fault tolerance and security.
In one embodiment, as shown in fig. 6, in step S70, the updating the data of the micro service cache according to the updated data specifically includes the following steps:
S71: and traversing and searching the data corresponding to the unique identifier in the data cached by the micro service.
S72: and if the data corresponding to the unique identifier exists in the data cached by the micro service, updating the data corresponding to the unique identifier in the data cached by the micro service by using the updating data.
S73: and if the data corresponding to the unique identifier does not exist in the data cached by the micro service, adding the updated data into the data cached by the micro service.
In one embodiment, the micro-service caches the target data used by all the micro-services in the data cache pool of the memory. When the micro service receives the data change notification, all cache data in the data cache pool of the micro service need to be traversed and inquired according to the data change notification. If the corresponding cache data exists, the cache data is updated according to the target data, and if the corresponding cache data does not exist, the target data is added in the data cache pool.
