摘　　要：针对企业应用系统集成Web service与ESB方案中存在的单向、基础平台等问题,利用OSGI框架在模块化、生命周期、组件执行环境以及基础服务方面的优势,在OSGI框架基础上,利用Java技术实现对现有应用的封装搭建服务程序,搭建专门用于通信管理的服务管理器程序,约定服务程序和服务管理器及服务管理器之间的通信与管理内容,构建一个完全统一、高效、高质、具有良好扩展性与可维护性的完全分布式企业集成框架OD-EAI。给出一个应用案例来说明该框架的使用方法。Aiming at solving the problems existing in the Web service and ESB methods such as the one-way and the basic-plat- form for building an enterprise application integration systems （EAI）, as the OSGI framework has advantages on the aspects of the module, the life cycle, the execution environment and the basic service management, Java technologies were used to encapsulate existing applications to build OSGI-based service programs, OSGI-based service managers specially for the communication between service programs and service managers as well as between managers were built. The OSGI-based distributed EAI practice framework OD-EAI is unified, highly qualified, extendible and maintainable. A specific case was given to illustrate the use of the OD-EAI.
