【摘要】 随着社会和经济的发展,信息系统在企业发展和竞争中的重要性不断提高,在激烈的竞争环境下企业业务调整加速,导致信息系统结构也不断调整,严重降低了信息系统的稳定性和使用寿命。工作流技术是信息系统新的发展趋势,采用了工作流技术的工作流管理系统将业务流程抽取出来进行统一管理,使信息系统的结构变得更加清晰,能够迅速响应业务流程的调整,对工作流技术进行深入研究对提高企业信息化具有重要的意义。本文以JBPM为研究对象来探讨工作流技术的工作原理,研究了工作流技术在工作流管理系统中的具体应用方式。本文在JBPM的基础上对其流程管理的薄弱环节进行了功能扩展,使用JBPM流程设计器为信贷审批流程建模,基于JBPM工作流引擎、Struts2、Hibernate等开源组件,采用多层结构提出了信贷系统审批子系统的架构方案,使用JBPM及其扩展功能实现了信贷审批流程。本文从工作流原理、工作流实现技术到工作流应用系统的实现三个层次分别进行了阐述,并详细说明了三个层次间的关系,为工作流应用系统的设计和实现提供了有效的参考。更多还原

【Abstract】 With the development of social and economic, the importance of the information systems in enterprise development and competition is increasing. Businesses adjustment accelerates in the fierce competitive environment, which leads to constantly adjustment of the information systems structure. Then the stability and life of information systems severely reduces. Workflow technology is a new development trend of information systems. The business process is extracted and managed integratedly by the workflow management system which introduces workflow technology. The information system structure becomes clearer and responds quickly to business process adjustment. It is significant on the depth research of workflow technology to improve enterprise informatization. In this paper, jBPM is acted as research object to explore the working principle of workflow technology and the specific application way in the workflow management system.This paper expands the weak features of jBPM based on the current version. This paper uses the jBPM Process Designer to design the flow model for the credit approval process, gives the system architecture of the credit system’s approval subsystem with multi-layer structure based on the open source components of jBPM workflow engine, Struts2 and Hibernate, and implements the credit approval process with jBPM and its expansion features. In this paper, the three levels from workflow theory, workflow technology to the implementation of workflow application systems are elaborated, and the relationship between the three levels is described in details, which provides an effective reference to design and implement workflow application systems.更多还原
