The Research And Application Of Financial Approval System Based On JBPM

To satisfy the demand of daily financial management,check and approval, financial management system has become one of the most important part of every enterprise and organization in the process of information development.How to separate the process logic from the business logic is very important to improve the flexibility and maintenance of the system.So It's of high significance to study software application based on workflow technology.This paper introduces the technology about workflow and workflow engine fistly, especially the open source workflow engine jBPM.After comparing the traditional workflow patterns and finance flow patterns,it points out the disadvantage of current workflow meta-model.By expanding the workflow meta-model on the base of traditional workflow modeling methods,it brings about an improved workflow construction which can provide stronger support in process model and organization model,so it supplies a good practical design idea for the design of workflow system. It adopts jBPM as a workflow engine for applied research,after reasearching the expansion mechanism,expasion point and expasion method of jBPM,it solves practical problems such as specific workflow patterns and workflow dynamic change in financial system by expanding jBPM.After that in accordance with the analysis of the system function,this paper presents the design and implementation of a finance approval system,describes the system's structure,the realization of workflow enginee in the system,the organization model,the approval flow and the transaction processing.In order to solve the special requirements,it brings about the implementation methods of jump,withdrawal, multisubprocess and support the dynamic change of flow,which improves the flexibility of the system.
