Description

Service arrangement and business flow processing method and device applied to SaaS

Technical Field

The invention relates to the technical field of computers, in particular to a service arrangement and business process processing method and device applied to SaaS.

Background

At present, cloud computing technology and business services are rapidly developed, and more enterprises start to purchase SaaS (Software-as-a-Service) enterprise services. Based on different business requirements, different enterprises put forward business customizable requirements on the internet information technology, namely, pages, processes, data and the like are expanded and customized according to the business requirements of the different enterprises through technical means.

The existing SaaS service provider performs parameterization processing on standard services, and then configures parameter values for users in specific business modes. But for complex services, if parameter resolution cannot be achieved, customized development needs to be carried out and then the services are deployed into independent service systems.

In the process of implementing the invention, the inventor finds that the prior art has at least the following problems:

1. the parameter management module and the preset parameter processing logic of the standard service need to be developed, so that the development cost is high, and the various requirements of users are difficult to meet through the parameters;

2. services beyond the standard can only be developed by customization, and need to be integrated with standard services after development, but because developers of the two are different in habits or different in systems, the problem that the integration specifications are difficult to unify exists;

3. the service flow of the user changes frequently (for example, a face recognition link is added), and the standard SaaS service is difficult to perform flow arrangement through parameters; however, the customization by the service provider is difficult to be completed in a short time, so that the service requirement of the user cannot be quickly responded;

4. at present, services are generally acquired by constructing a distributed service bus, and a service system is required to develop a service interface strictly according to a standard service interface specification, and then register the service interface into the distributed service bus, which has two disadvantages:

performance problems: when a high-concurrency request is used for processing a large-scale document, the memory usage amount is too high, so that the bus is blocked, and the distributed service bus positioning service can not be executed;

expanding the threshold height: customized teams need to develop customized services according to standard service interface specifications, and the specifications are not a published standard specification, resulting in limited service extensibility.

Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

It should be noted that the embodiment of the present invention is applicable to the fields requiring services, such as finance, sales, personnel, enterprise management, catering, transportation, and the like.

The words to which the invention relates are to be construed as follows:

customized development: the software system which is relatively mature is changed correspondingly according to the requirements of customers.

Event: is a behavior that can be detected by JavaScript. Each element in the web page may generate certain events that may trigger JavaScript functions.

Micro-services: an emerging software architecture is to split a large single application and service into tens of supporting microservices. A microservice policy may facilitate work by extending individual components rather than the entire application stack to meet service level agreements.

Service arrangement: and combining the atomic services through a visual service arrangement mode to form the combined service of the general service scene.

Distributed service bus: and realizing a registration and discovery mechanism of the microservice. After the micro-service is released, the name of the micro-service is published. The information such as addresses is registered in the distributed service bus (service registration), and service addressing can be realized through the service registration information.

Referring to fig. 1, a main flowchart of a service orchestration method applied to SaaS according to an embodiment of the present invention is shown, including the following steps:

s101: receiving a service calling request, analyzing the service calling request, and acquiring a target service identifier to be called;

s102: if the target service corresponding to the target service identification does not exist in the preset service list, acquiring the micro service and/or the combined service corresponding to the target service identification;

s103: orchestrating the acquired micro-services and/or composite services to generate the target service.

In the above embodiment, as for step S101, the SaaS service provides a service interface that can be operated by a user (named tenant in computer speciality), and the user can create a business process belonging to the user using the service interface.

In the process of generating the business process, a visual service arrangement management interface, a process design interface and the like can be set, and the invention mainly aims at the two.

The service arrangement management interface can display an arrangeable service list, so that enterprise developers can select required services on the list or a computer analyzes business requirements and selects the services.

The displayed service list can be a name list of each service or a service primitive list, arrangement and the like; corresponding operation functions such as dragging, clicking, attribute setting and the like can be set for the services. For example, a developer drags a service primitive to a calling position corresponding to a business process; and then clicking the service primitive to send a service calling request to the service arranging and managing interface.

For example, user X creates a set of information verification process Y, which first performs a user name verification and then performs a face identification verification.

Therefore, for a received service call request, a target service to be called, for example, a face recognition service needs to be determined, and then the target service is searched through the identification of the face recognition service.

For steps S102 and S103, for the services in the service orchestration management interface, a service resource library may be pre-constructed, where the library includes micro services or composite services, or both; the combined service is obtained by performing service arrangement on a plurality of micro services in advance.

The number of services in the service list may be less than or equal to the number of services in the service repository; for example, if the number of services in the service resource library is small, all the services may be displayed in the service list; if the number of services in the service resource pool is large, part of the services (for example, common services, which can also be understood as standard services) can be displayed in the service list, and the number of the services is preferably set to be equal.

Furthermore, a service search function can be set, so that developers can quickly locate required services based on service information.

According to the identification of the target service, inquiring in a service list:

1) if the called target service, such as a user name verification service, exists in the service list, the service can be directly extracted from the service resource library and stored to the calling position corresponding to the service calling request, so that the service calling required by the business process design in the current link is realized. Typically, standard services are stored in a database and can be queried in a service list.

2) However, if the target service, for example, the face recognition service, does not exist in the service list, it indicates that the service does not exist in the existing service resource library, and needs to be newly generated. These services, which are typically required by the user himself, but may not be required by other users, i.e. customized services:

firstly, a user can customize customized service according to self needs, and the service is added into a service resource library to realize service updating in the service resource library.

Therefore, the function of adding new services, or the functions of service updating, service modification, service deletion and service searching can be set in the service resource library, so that the functions of flexibly managing the service resource library and expanding services are provided for developers, and the direct calling of subsequent services is facilitated. A service list update function may also be provided, the number of services in the service list varying with the number of services in the service repository.

Secondly, in order to meet the requirement of the target service in the process of designing the business process, micro-service and/or combined service which can be arranged as the target service can be obtained based on identification information such as the name, the address and the like of the target service, and then the micro-service and/or the combined service is arranged to obtain the target service to be called.

Therefore, a visual primitive arranging component can be preset, and visual service arrangement can be performed on the micro-service and/or the combined service through visual dragging or configuration and the like.

The method provided by the embodiment can perform service arrangement based on the existing micro-services and/or combined services to obtain the target service to be called when the service design requirement exists, realizes service expansion, and provides service support for subsequent customized service process design. And for standard services and customized services, integration can be performed through a service interface, so that the problem that the integration specifications in the prior art are difficult to unify is solved, the service development cost is reduced, and a good implementation effect is achieved.

Referring to fig. 2, a main flowchart of an optional service orchestration method applied to SaaS according to an embodiment of the present invention is shown, including the following steps:

s201: receiving a service calling request, analyzing the service calling request, and acquiring a target service identifier to be called;

s202: if the target service corresponding to the target service identification does not exist in the preset service list, acquiring the micro service and/or the combined service corresponding to the target service identification;

s203: orchestrating the acquired micro-services and/or composite services to generate the target service;

s204: receiving input of a subscription theme message in each target service;

s205: and arranging and combining the process links corresponding to the target services according to the arrangement sequence of the input subscription theme messages to obtain the business process.

In the above embodiment, the descriptions of steps S101 to S103 shown in fig. 1 can be referred to for steps S201 to S203, respectively, and are not repeated herein.

Service orchestration provides a new way for application development and operation and maintenance to cover all the dynamic lifecycle of distributed applications, which can be deployed into the production environment in a short time when new code or new containerized services change, their unique modular structure determines that it can be used by different people, including developers, operation and maintenance people and their partners.

In the above embodiment, for step S204, the topic is a specific event type of message publishing or client Subscription (Subscription) notification. It serves as a channel for sending messages and subscription notifications, providing a channel for publishers and subscribers to communicate with each other.

If a subscriber, i.e. an object receiving a message from a topic, wants to receive a message published to the topic, the subscriber must be added to the topic, and the message subscriber can receive the message published to the topic by the publisher only if a subscription relationship is established with the topic.

And subscribing the subject message, which is necessary basis for the service to view the event from the message queue center and corresponds to the target service. For example, the username verification service listens for Event1 in the message queue center by subscribing to topic message B.

For step S205, there is a corresponding relationship between the service and the process link, for example, the user name verification service corresponds to the user name verification link, and the face recognition service corresponds to the face recognition link.

The business process is composed of process links, so in the design process of the business process, after the target service is determined, the process links also need to be determined.

The process links in the business process have a sequence in execution, and can be determined according to the service icon dragged by a developer on a service arrangement management interface, and also can be determined according to the order of the subscription theme messages input by the developer. For example, for user name verification and face recognition in the information verification Y, if the subscription topic message corresponds to B and C, respectively, it means that user name verification is performed first, and then face recognition is performed.

After the required business process is generated through the business process design, the business process can be issued to the corresponding business system, and the issued business process is essentially the business process on the model level at the moment and can also be called as a business process model.

Then, when there is a need to run the business process, a developer can perform corresponding configuration on the published business process model in cooperation with the actual application scenario of the business system to obtain an executable instantiated business process.

It should be noted that, for the subscription topic message a, the identifier indicating the end may be set in the service orchestration management interface by the developer. The present invention is not limited herein with respect to the setting of the subscription topic message.

After the business process is generated, further, a service arrangement definition model may be established, and the model may be a database, or a container such as a folder and the like that can store information. For example, the SaaS service interface integrates user information X, information verification process Y, and subscription topic messages B and C, and stores the integrated information into the service orchestration definition model Z, so as to complete the storage operation of the design interface, and business personnel can develop their business processes in the published process model.

It should be noted that the service orchestration definition model here is only a data set organized in a tree structure, and has a business meaning and a stable data structure, which can be regarded as parameter passing of service invocation. The contained information can only be read, can not be modified, and even if modified, can only be modified in the service orchestration management interface.

In addition, once the business process is called to run, the business process instance is generated, so the relationship between the service arrangement definition model and the number of the process instances can be 1: and N is added.

Furthermore, for different users, service isolation, business process isolation and model isolation can be performed based on user information. For example, a service orchestration definition model 1 for a user 1 is provided, which service orchestration definition model 1 may in turn contain a plurality of small service orchestration definition models, e.g., a model 11 for a business process 11, a model 12 for a business process 12.

The method for obtaining the service through the distributed service bus of the cloud platform does not support isolation for the obtained service and the obtained business process. According to the invention, through the user information, the business process identification and the set service arrangement definition model, the isolation of the user information is realized, the condition of confusion of business process calling is avoided, the service can be provided for a plurality of tenants, and the application range is wider.

The generated service orchestration definition model may be stored by an extensible XML file, the main contents of which include: the system comprises service link information, service flow information, overtime playback information, service gateway information, message queue subject information, abnormal branch information, user information, parameter information, extension information and the like.

The method provided by the embodiment provides the function of maintaining the business process for the user, and the user can modify the business process of the SaaS service at any time through the service interface, adjust the execution sequence of the process links and achieve the aim of quickly generating the business process at low cost. In addition, different service arrangement definition models are set for different user information, so that the isolation of the user information is realized; and the service arrangement system is not required to be established for each user, and the service can be provided for multiple users only through the service arrangement mechanism.

Referring to fig. 3, a main flowchart of a service flow processing method applied to SaaS according to an embodiment of the present invention is shown, including the following steps:

s301: receiving a business service request, and acquiring user information and a business process identifier in the business service request;

s302: determining a service process and a subscription subject message corresponding to the user information and the service process identifier, and triggering a process link corresponding to the subscription subject message in the service process;

s303: and after all the process links in the business process are executed, transmitting an execution result to the business process information corresponding to the business process identifier.

In the above embodiment, for step S301, the user applies the SaaS service to create a business process belonging to the user, and develops the business process of the user in the released process model.

For example, a service person performs a service flow by using a SaaS service, and a standard service entry of the SaaS service receives a service request, and analyzes and obtains user information and a service flow identifier in the request, such as user information X and an information check identifier Y.

The user information may be an identity card number, a taxpayer identification number of an enterprise, a registration number in the SaaS service, or other forms.

For step S302, the same user may establish multiple service flows, and the names of the service flows that may be established by different users are the same, for example, an information verification flow. Therefore, the business process of the service requested by the business personnel of the enterprise at this time can be determined according to the user information and the business process identification.

For example, the standard service entry takes the user information X and the information check identifier Y as query conditions, obtains a service arrangement definition model Z corresponding to the query conditions through a service arrangement query module, and then sends the service arrangement definition model Z to a service scheduling center;

and the service scheduling center receives the service arrangement definition model Z, analyzes the service arrangement information (namely the user information X and the information verification identifier Y), determines an information verification process Y created by the enterprise and starts the information verification process Y.

The business process can be triggered based on a service request received by a standard business entry, and the process link is mainly triggered based on a subscription theme message. A business process may include a plurality of process elements, and the order of execution of the process elements may be determined according to the order in which the subject messages are subscribed.

For example, in the information verification Y, a user name verification link needs to be triggered through the subscription theme B, and a face recognition link needs to be triggered through the subscription theme C, and the two subscription theme messages can be found in the service arrangement definition model Z as well.

After the execution of each flow link is finished, the execution result is transmitted to the flow information in the service scheduling center for storage, for example, user name verification is performed, the input data is verified to obtain a verification result, and the result is stored in the information of the information verification flow. For specific execution operations of the process link, the following description of fig. 4 is specifically referred to, and details are not repeated here.

For step S303, after the last process link in the service process is completed, the process center (the whole set of solution is regarded as the process center) notifies the service scheduling center that all process links in the current process are completed, and then the process is completed.

The user can obtain a processing result returned by the SaaS service by inquiring the service application interface, and the service flow is completed.

The processing result here may be a union of execution results of all the flows, and each time one flow link is executed, the corresponding execution result is added to the flow information Y.

Further, the service scheduling center may perform a packet marking on the returned execution result according to the execution sequence of the flow links, for example, the marking processing result 1 is a result of checking the user name.

However, it should be noted that, for a business process including a plurality of process links, after one process link is executed, the processing result is not directly returned to the user. However, when the service flow is finished, the scheduling center sends a message that the current service flow is finished to the message center, for example, the flow processing service monitors the message, finds that the information verification flow Y is finished by analyzing the content of the message, and can query the scheduling center according to Y to obtain a detailed execution result of the whole information verification flow Y, specifically, the user information X, the input data, the verification result information, the acquired face information, and the like.

The method provided by the embodiment determines the business process through the user information and the business process identifier, so that the accuracy of determining the business process is improved; compared with the existing mode of transmitting events by different services aiming at different business processes, the invention transmits the events through the service scheduling center, improves the operation capability of the whole process center, and can be oriented to the operation and monitoring of all the business processes.

Referring to fig. 4, a main flowchart of an optional service flow processing method applied to SaaS provided in the embodiment of the present invention is shown, including the following steps:

s401: receiving a business service request, and acquiring user information and a business process identifier in the business service request;

s402: determining a business process and a subscription subject message corresponding to the user information and the business process identifier;

s403: determining first subscription subject messages which are ranked first according to the ranking sequence of the subscription subject messages, and sending events with the topics being the first subscription subject messages to a queue center;

s404: through the first subscription subject message, the first service monitors and analyzes the event in the queue center to obtain a business process identifier in the event;

s405: if the acquired service flow identification is the service flow identification of the service flow, the first service acquires and executes a task corresponding to the event;

s406: after the first process link is executed, determining second subscription subject messages for sorting second, triggering second services corresponding to the second subscription subject messages, and repeating the event transmission and event analysis steps until all process links in the service process are executed;

s407: and after all the process links in the service process are executed, transmitting an execution result to the service process information corresponding to the service process identifier.

In the above embodiment, the descriptions of steps S301 to S303 shown in fig. 3 can be referred to for steps S401, S402, and S407, respectively, and are not repeated herein.

In the above embodiment, for steps S403 to S406, the number of process links in the business process may be large, and since data between each process link has processing relevance, the process links need to be executed in sequence.

Specifically, judging according to the subscription theme message; for example, a user name verification link corresponding to the subscription topic message B is triggered first.

In the process of executing the first process link, namely user name verification, namely the service scheduling center sends an Event to the message queue center. The event content may include detailed information of the business process, such as user information, process identification, business documents, and the like.

Furthermore, the service dispatching center firstly generates tasks corresponding to the user information, the business process identification and the process link, and then sends corresponding events to the message queue center.

However, a process link may be multiplexed by a plurality of business processes, and a business process may also be invoked by a plurality of users, so for a single process link, the number of events sent by the service scheduling center may be large (distributed or recurrent), for example, for process Y, process Y'.

After the flow link receives the execution instruction, it needs to know which business flow is calling it, so the invention needs to analyze the event information, and the analyzing step is not few.

For example, for the first user name checking link in the information checking Y, the user name checking service monitors the Event1 in the message queue through the subscription topic B, and obtains the information of the business process Y (or the parameter of the process instance) by parsing the Event1, thereby determining that the self service is called by the information checking Y.

After the flow link determines the called service flow, a task corresponding to the event can be determined as a task to be processed; further, the task can be claimed and executed from the service scheduling center according to the user information, the business process identification and the subscription subject message.

Since the service scheduling center may be directed to a plurality of SaaS services, for the distribution of an event, the service scheduling center may send the event in the plurality of SaaS services, or may repeatedly send the event. In order to prevent the task from being processed repeatedly, an exclusive mechanism can be added, and once the task is claimed, the task is successfully claimed, so that the life cycle of the whole process is improved.

For example, the username verification service determines that the task corresponding to Event1 is a pending task and claims at the service dispatch center, indicating that the claim was successful once the task was claimed.

The first process link processes the task (the process may require a certain time), and when the task is completed, the first process link notifies the service scheduling center, and submits a corresponding processing result to the service scheduling center, for example, the inputted user name is checked, and the result is transmitted to the information of the service scheduling center process Y.

In summary, the operations performed by the flow link include: monitoring events to determine tasks to be processed, sending a claim task request to a service scheduling center, and submitting task processing results to the service scheduling center after the tasks are processed.

After receiving the task completion information returned by the first process link, the service scheduling center determines a second process link and sends an event corresponding to the second subscription theme message to the queue center. For example, for the face recognition link in info check Y, the service dispatch center sends an Event2 with topic C to the message queue center.

The second process link still listens to the events in the message queue center through the corresponding subscription topic message, for example, the Event2 is listened to through the subscription topic message C. The subsequent operation steps are consistent with the first process link, and are not described herein again.

In the method provided by the embodiment, the scheduling center is responsible for sending the event to the message queue center, so that a mode that the event service is required to be distributed according to different business processes is replaced, the operation capacity of distributing the event in the whole process is improved, and the requirements of code generation and test are reduced; the execution sequence of the process links is determined by subscribing the topic message, which is also beneficial to the effective execution of the business process.

Referring to fig. 5, a schematic diagram of an implementation process specifically applied to SaaS service in an embodiment of the present invention is shown, and mainly includes two parts: a service arrangement management center and a service arrangement operation center.

1. The service arrangement management center is mainly used for arranging service and generating business processes. The system mainly comprises a service arrangement management interface, a service arrangement management module and a service arrangement definition model; wherein:

1) service orchestration management interface: visually displaying the arrangeable service list according to the received service calling request; such as username verification;

2) the service arrangement management module: when no service exists, arranging and generating corresponding customized service based on the existing micro service and/or combined service, and updating a service resource library and a service list; such as face recognition; and
