[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] like Figure 1a As shown, it is a schematic diagram of the architecture of a workflow engine provided in an embodiment of the present application, including:

[0055] Client 100 and server 200.

[0056] Among them, the client 100 is deployed in the business service, and is used to send service requests to the server 200, update the status information of the process instance, and store the status information of the process instance in the business service. As a separate stateless microservice, the server 200 only provides process node query services and the function of generating an ID corresponding to the process instance. In an embodiment of the present application, the dynamic data of the process (such as process instances, process tasks) is stored in the business service, and the static data of the process (such as process templates, process nodes, process branch tables, etc.) is stored in the server 200.

[0057] It should be noted that the specific process of using the workflow engine to process the workflow, such as Figure 1b As shown, the following steps are included:

[0058] S101: When receiving a service request sent by a business service based on a business process flow, the client obtains process dynamic data and user parameters corresponding to the service request from a business database.

[0059] The business database is a database deployed in the business service, and the service request includes but is not limited to a process initiation request, a process node completion request, and a process node jump request. In addition, the process dynamic data is obtained by the business service performing business processing based on the request instruction sent by the user.

[0060] It should be noted that after receiving the request instruction sent by the user, the business service executes the business processing flow corresponding to the request instruction and obtains business information (business information includes process dynamic data and user parameters). After saving the business information in the business database, the business service will call the preset client interface and send a service request to the client.

[0061] S102: The client calls a preset server interface and sends process dynamic data and user parameters to the server.

[0062] S103: The server obtains process static data corresponding to the user parameters from the target database.

[0063] The target database is the database deployed in the server. In addition, the process static data includes process templates, process nodes and process branch tables.

[0064] S104: The server calculates the ID corresponding to the process instance and the execution node corresponding to the process task based on the process template, the process node and the process branch table.

[0065] S105: The server sends the ID corresponding to the process instance and the execution node corresponding to the process task to the client.

[0066] S106: The client stores the ID corresponding to the process instance and the execution node corresponding to the process task in the business database.

[0067] It should be noted that Figure 1b The interaction process shown can be seen in Figure 1c The application scenario shown.

[0068] Based on the above process shown in S101-S106, when the business service uses the workflow engine to run the business process, because the workflow engine includes a server and a client, the process static data is stored on the server, and the process dynamic data is stored in the business service. Because the server does not save any process operation related data, it only involves the local transaction of the business service, avoiding the problem of global distributed transactions, and only involves the local transaction of the business service, ensuring the consistency of global data, and through the loose coupling design, the business service is more independent and conducive to expansion.

[0069] In summary, by using the solution shown in this embodiment, the static data of the process is stored in the target database, and the dynamic data of the process is stored in the business database, which can effectively prevent the problem of distributed transactions from occurring during the workflow processing.

[0070] like Figure 2 FIG. 1 is a schematic diagram of a workflow processing method provided in an embodiment of the present application, which is applied to a client and includes the following steps:

[0071] S201: When receiving a service request sent by a business service based on a business process flow, process dynamic data and user parameters corresponding to the service request are acquired from a business database.

[0072] Among them, the business database is the database deployed in the business service; the process dynamic data includes the process instance.

[0073] S202: Calling a preset server interface to send process dynamic data and user parameters to the server.

[0074] S203: receiving feedback results sent by the server based on process dynamic data and user parameters.

[0075] The feedback result includes an ID corresponding to the process instance.

[0076] S204: Store the ID corresponding to the process instance in the business database.

[0077] In summary, by using the solution shown in this embodiment, the static data of the process is stored in the target database, and the dynamic data of the process is stored in the business database, which can effectively prevent the problem of distributed transactions from occurring during the workflow processing.

[0078] like Figure 3 FIG. 1 is a schematic diagram of another workflow processing method provided in an embodiment of the present application, which is applied to a server and includes the following steps:
