基于发布/订阅的消息队列在工作流引擎中的应用研究

摘要

Whether in workflow model or in workflow management system, workflow engine plays a very important role. In workflow management system, workflow engine delivers the messages between different users and implementers as a task manager. A good message transfer mechanism can effectively improve the work efficiency of the workflow engine, thereby improving the efficiency of the workflow system. This paper proposes a message queue based on publish/subscribe to deliver to deliver messages. It can improve the efficiency of the workflow engine and workflow management system.%不论在工作流基本模型中还是在工作流管理系统中,工作流引擎都起着非常重要的作用.对于工作流管理系统,工作流引擎是任务管理器,在不同的使用者和执行者之间传递消息,因此一个好的消息传递机制,能够有效地提高工作流引擎的工作效率,从而提高工作流系统的效率.本文提出一种基于发布/订阅的消息队列机制,对于提高工作流引擎消息传递的效率有很大帮助.
