【摘要】 工作流是能够完全或者部分自动执行的经营过程,它根据一系列过程规则,使文档、信息或任务能够在不同的执行者之间传递与执行。工作流管理系统是以计算机支持的分布式、协同工作业务流程的自动或半自动化为研究目标的软件系统。随着计算机网络,特别是Internet/Intranet的迅速发展和应用,计算机支持的分布式、协同工作的工作流管理系统在企、事业单位中的地位显得越来越重要,也有着广阔的前景。本文首先研究了工作流管理系统的起源、现状、发展趋势,然后详细分析了工作流的相关概念,阐述了工作流管理系统的分类以及主要功能,最后针对工作流管理联盟提出的一系列规范,对其从体系结构、流程建模、工作流执行服务等方面进行了探讨,并在研究工作流引擎关键技术的基础上,比较了当前几种流行开源工作流引擎,对OSWorkflow工作流引擎进行了深入的研究与分析。本文基于J2EE架构,利用Struts、Hibernate、Spring、XML等主流技术,探讨了基于J2EE和OSWorkflow的工作流管理系统的实现,并通过设计一个典型的工作流模块验证了其可行性。本文提出的基于J2EE和OSWorkflow的工作流管理系统具有灵活的流程定制功能及非常好的安全性和稳定性,具备良好的扩展能力。更多还原

【Abstract】 The workflow is a management process which can be executed automatically or half-automatically according to a series of rules. It can transfer documents, information and tasks between different executors.The workflow Management System is a kind of software with the research object of implementing a distributed, cooperated business progress that can be executed automatically or half-automatically based on computer. As the rapid development and application of internet / intranet, distributed, cooperated business progress based on computer becomes more and more important in enterprises, and it also has a broad future.This paper starts with the research of the origin, actuality and development of Workflow, then the author analyses some interrelated conceptions of workflow in a detailed way, mainly about the classify method and functions. At last, the author discusses the system architecture, workflow modeling, and workflow executive-service based on the specifications of Workflow Management Coalition. Further more, after comparing some popular open-source workflow engine the author makes an deep research on OSWorkflow.This paper is based on J2EE architecture and uses many popular technology such as Struts、Hibernate, Spring, XML and so on. By designing and implementing a classical workflow module the feasibility of the new Workflow Management System is validated.The Workflow Management System prompted by this paper has a feasible characteristic of customization, excellence security, stability and expansibility更多还原
