Abstract

The invention discloses a workflow engine and an implementation method of the workflow engine. The workflow engine and the implementation method of the workflow engine are used for reducing the network communication overhead. The workflow engine is downloaded to a browser of a client through a browser from a network server to carry out loading and running. The workflow engine comprises a workflow analyzer and a workflow execution controller, wherein the workflow analyzer is used for reading a workflow configuration file, analyzing a workflow definition model in the workflow configuration file, and generating a workflow instruction which is executed by the workflow execution controller, the workflow execution controller is used for loading a service object of a current workflow node according to the workflow instruction, and carrying out initialization; after operation of a corresponding service is accomplished, result data of service operation are calculated according to an arithmetic logic expression of the current workflow node; judgment is carried out on skip conditions of the current workflow node, if the current workflow node is a workflow end node, the workflow of the workflow engine is ended, if matching of a next workflow node is successful, the next workflow node is determined as the current workflow node, and the step of loading the service object of the current workflow node and the follow-up steps are continuously executed.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a workflow engine and its implementation method. Background technique [0002] In the computer environment, workflow is the process of transferring documents, information or tasks among multiple participants according to a certain pre-set process. The core of realizing the workflow is the workflow engine, or process engine, which provides implementation for the definition and interpretation of the process, the way and path of information transmission, the division of labor and conditions of roles, etc. A workflow node is a step or link in the process, generally corresponding to an application in the application system, and one or more workflow nodes can be connected to form a workflow through the workflow engine. [0003] In the existing technology, most of the commercial workflow engine products adopt the stand-alone application mode. The stand-alone means that the workflow e...
