【摘要】 传统的企业应用集成技术受软件开发模式和系统集成方法的限制,造成了企业的各个应用系统之间紧密耦合的状态,不利于企业的系统升级和拓展。另外传统的企业应用集成技术主要是为了实现企业内部的信息流通和共享,对企业之间的应用集成支持较差,无法适应极端异构的网络环境和日益增多的电子商务要求。Web Services技术以其协议的通用性、完全的平台无关性和语言无关性,能够弥补企业应用集成技术的不足之处。 文中提出基于Web Services的企业应用集成解决方案,设计基于Web Services的企业应用集成框架—WS EAI框架。其基本思路是:将企业原有的各系统封装成Web服务,并发布其服务描述到服务注册机构,各类Web服务客户端应用都能通过查询服务注册机构而发现并最终调用服务,实现了企业内外应用系统间的松散耦合。由于Java的跨平台性,J2EE具有可扩展性,支持合理的集成和灵活的部署,本文选用J2EE架构作为应用WS EAI框架的平台,研究J2EE平台上基于Web Services的企业应用集成,并设计了实现模型,论述了其中的关键技术。

【Abstract】 Traditional EAI technology is confined to software development mode and system integration methods, which lead to compact coupling among enterprise application systems, and blocks enterprise’ s system upgrade and development. Besides, traditional EAI technology focuses on information currency and share inside enterprise and sustains application integration among enterprise poorly, which can not fit for extremely heterogeneous network environment and increasing demand of EC. With characters of protocol currency, platform independency and language independency, Web Services will fetch up to EAI.A EAI solution based on Web Services is proposed, the solution means to pack enterprise legacy systems to Web Service and publish service descriptions to service registry,then all Web Services clients can query registry and invoke service, thus realizes the loosely coupled enterprise application systems. With the reference to J2EE criterions, J2EE platform is used to apply WS EAI framework, the realizing model is gived and the key technologies are discussed.
