摘　　要：针对企业应用集成(EAI:Enterprise App lication Integration)的3种传统解决方案,即数据级集成、应用接口级集成和业务逻辑级集成中存在的数据安全性差、业务逻辑保密性差和紧耦合性等局限性问题,提出了采用SOA(Service-O riented Arch itecture)模型的企业应用集成方法,并讨论了相关的支撑技术,给出了W eb服务集成实现模型———网络通信层、消息传输层、服务描述层、服务发现层、服务保证层和服务组合层。结果表明,新的架构具有敏捷性、松耦合、跨平台、分布式的特点,更能适应企业信息系统发展的需要。采用面向服务的架构实现企业应用集成的方式,能较好地解决企业原有应用系统集成的问题,从而克服了EAI传统解决方案中的数据安全性差、业务流程不保密、应用系统间紧耦合等缺点,建立了一套独立于语言并且跨平台的系统集成方案。不仅保留了企业原有资源,节省软件开发成本近40%,而且为业务流程的变更提供了很好的灵活性,为企业未来业务发展提供了良好的环境。Aim at the limits of the traditional methods （Data Layer Integration, Interface Layer Integration and Business Layer Integration） on EAI （Enterprise Application Integration）, such as data insecurity, logic inseeurity and tight coupling, this paper presented a new EAI model that was based on SOA （Service-Oriented Arehiteeture） and introduced its implementation technology. Then the realized model of Web service （network communication layer, message transmission layer, service descript layer, service discovery layer, service guarantee layer and service integration layer） was brought up. Result indicated that new architecture had many advantages, such as promptness, loose coupling, platfDrm-independent and distributing and it was more adapt to EAI than any of the traditional methods. Service Oriented EAI conquered the disadvantages of the traditional EAI methods, and gave a language-independent and platform-independent EAI method. Such method could reserve the quondam resource of the enterprise and save the cost on development. In respect to serviceoriented EAI was propitious to the alteration of enterprise＇s business, it would promote the development of enterprise rapidly.
