介绍了面向服务架构(SOA)的基本概念和工作原理,以中间件技术为基础,提出了一种基于SOA的中间件应用集成框架,框架采用服务分层模型,具有敏捷性、松耦合、跨平台、分布式的特点,可广泛适应信息系统集成发展的需要,分析了基于SOA的企业应用集成的优点,设计了基于SOA的企业应用集成体系结构,研究了其实现的关键技术,给出了基于SOA架构的中间件应用集成方案,以消息中间件将系统流程集成起来,最后给出了相应的应用案例.%The basic concept and operating principle of service-oriented architecture (SOA) are introduced, and a SOA-based enterprise application integration (EAI) framework dependent on the middleware is proposed. The framework adopts service hierarchy model, which is agile,loosely coupled, platform-independent, distributed and more suitable for the development of information system. The advantage of the enterprise application integration based on SOA is analyzed,the architecture of the enterprise application integration based on SOA is designed, and the key technology is studied. Furthermore, the SOA-based application integration scheme is put forward, in which the system processes are integrated by message-oriented middleware, and corresponding examples are presented.
