Description

Technical Field

[0001] The present invention relates to the technical field of event-driven, and particularly to an event-driven implementation method, system, device and storage medium based on process control. Background Art

[0002] In the context of an event-driven architecture, usually an event needs to transfer data between a publisher and multiple subscribers. The event message specification is formulated by the event publisher. Due to the inconsistency of data security and data standards, the transmission process of the event will involve the conversion of communication messages between the event publisher and the subscriber. However, the commonly used message conversion methods can only be adapted by the subscriber itself or the event publisher publishes different events according to the needs of different subscribers, which leads to the need for many additional processing mechanisms for the event publisher and the subscriber in the implementation process of the event-driven architecture. At the same time, the reusability of the event is also greatly reduced, and the event governance specification cannot be truly implemented. Summary of the Invention

[0014] Parallel: The nodes in the process are executed in parallel, and the calls between the parallel nodes are independent of each other and occur simultaneously;

[0015] Branch: Use one or several fields in the request message described by the event as conditions. The part that meets the conditions in the branch is executed, and the part that does not meet the conditions is skipped directly;

Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Referring to Figure 1 , the present invention provides a method for implementing event-driven based on process control, including:

[0029] The event publisher sends a request message, and the request message includes event identification conditions and necessary attributes for event processing;

[0030] Query process information based on the request message;

[0031] Execute the process according to the process configuration based on the process information, and complete the message sending according to the event subscription relationship;

[0032] Among them, the process is formulated according to the business attributes of the event, and the business attributes include the message format of the event, the unique identifier of the event, the message content of the event, the subscription relationship of the event, and the request method of the event-related service party; the process configuration includes the event source, event target, event-process binding, event subscriber, service request, event processing process, and message conversion rule.

[0033] In this embodiment, executing the process includes a message parsing and process handling program, and the process handling program includes a process scheduling program, a message adaptation program, and a data mapping program. Each program is uniquely bound to the event. The process handling program uses dynamic compilation technology to parse the configuration information into program code, dynamically compiles and runs the program code and loads it, identifies and invokes the process according to the request message, and calls the business service according to the process configuration during the process handling to query the service subscription relationship to complete the event process.

[0034] Specifically, the present application provides an event-driven architecture system, which realizes the orchestration of event processes in a process-based manner. Messages are transmitted between applications through a unified event specification, and data filling and message format conversion are realized through a configuration-based method.

[0035] Furthermore, during the event processing, the event publisher and the event subscriber transmit messages according to the event governance specification, and message conversion is realized by the event processing flow.

[0036] The event publisher and the event subscriber send and receive messages according to the event governance specification;

[0037] According to the process configuration information, the process parsing is completed. After receiving the request from the event publisher, the process processing realizes the scheduling and running of the process according to the binding relationship between the event and the process.

[0038] During the process running, it supports organizing the request information according to the event request content, and completing the data content filling and data mapping through the service call method.

[0039] After the process processing is completed, according to the subscription and publication relationship of the event, messages are sent according to the event governance specification.

[0040] In this embodiment, in the event-driven architecture, the event process is formulated according to the specific business attributes of the event, including the message format of the event, the unique identifier of the event, the message content of the event, the subscription relationship of the event, the request method of the event-related service party, etc. The event processing flow is configured in an interface-based manner, and the configuration includes: event source, event target, binding between event and process, event subscriber, service request, event processing flow, message conversion rule, etc. The event process method reduces the difficulty of implementing the event-driven architecture through a configuration-based method, realizes the unified management of the event governance specification, and improves the flexibility and consistency of event communication in the distributed system.

[0041] Specifically, the processing program for process parsing and process scheduling after receiving the requester. When the platform starts, the process processing module parses and dynamically generates a process processing program according to the configured process processing information. The process processing program includes a process scheduling program, a message adaptation program, a data mapping program, etc., and each process is uniquely bound to an event.

[0042] The process handler completes event process parsing and data mapping based on the event process developed by event developers. The process handling uses dynamic compilation technology to parse the process configuration information into program code, dynamically compile the running code and load it. After receiving an event request, the process handling module will complete the identification and invocation of the process according to the event request message information. During the process handling, the business service will be invoked according to the process configuration, and the service subscription relationship will be queried to complete the event process

[0043] The supported types during the process handling include:

[0044] Serial: The nodes in the process are executed in sequence one by one, and the subsequent nodes can obtain the execution results of the previous nodes when executing;

[0045] Parallel: The nodes in the process are executed in parallel, and the invocations between parallel nodes are independent of each other and occur simultaneously;
