Workflow data interaction method and device, electronic device and readable storage medium

Abstract

The invention provides a workflow data interaction method. The method comprises the steps that a data interaction mode between a service system and a workflow engine is selected; configuring a process design drawing in the workflow engine according to the business process of the business system; creating a starting node for the process design drawing according to the data interaction mode, and configuring a starting communication channel of a starting process and a function communication channel of a corresponding function node in the starting node; the workflow engine obtains service data of the service system according to the starting communication channel and starts a process instance corresponding to the process design drawing, the service data is converted into process data and then input into the process instance for circulation, and each process node generates new process data according to the input process data to continue circulation; and if the data is transferred to the function node, performing data interaction with the service system according to the corresponding function communication channel. According to the method, data interaction is provided between a service system and a workflow engine which are in different network environments or have strict requirements on the network environments.

Description

technical field [0001] The present application relates to the field of workflow data interaction, in particular to a workflow data interaction method, device, electronic device, and readable storage medium. Background technique [0002] In an information system, a workflow engine needs to be used to deal with a variety of business processes. Usually, multiple different business systems are connected to a workflow engine, and the process nodes in the business process are set according to the business logic of the business system. Dynamically assign processors, and return the process data of the business process to the business system for display or continue related business processing after the node status of each process node is updated. [0003] At present, although some workflow engines support the advancement of business processes across applications, they cannot satisfy the data interaction between business systems and workflow engines in a specific network environment. ...

AI Technical Summary

Problems solved by technology

[0003] At present, although some workflow engines support the advancement of business processes across applications, they cannot meet the data interaction between business systems and workflow engines in specific network environments.

For example: business systems and workflow engines deployed in the same network environment usually use message queue communication to promote business processes. This method uses message middleware as the communication medium, and the workflow engine ends at the end of the process instance process. Afterwards, the process data is sent to the message queue of the message middleware, and the business system monitors whether there is new process data in the message queue, but if the business system and the workflow engine are deployed in different network environments, and the message middleware is used for communication , the message middleware needs to be deployed in a network environment that can be accessed by both the workflow engine and the business system. For strict requirements on the network environment, it is impossible to provide a suitable network environment for deployment of the message middleware. Therefore, the business system and the work The streaming engine cannot communicate for data interaction
