面向SOA的企业服务总线研究与实现

针对企业日益增长的信息共享和业务整合的需求，面向SOA的企业服务总线屏蔽各类异构的应用从而实现基于SOA架构的企业应用集成是大势所趋。现有的面向SOA的企业服务总线（s-ESB）大多立足于提供Web服务容器，并没有提供统一的适配机制无缝集成各类企业应用，从而极大限制s-ESB的高可用性和可扩展性。首先，提出了一种新型的基于SOA架构的企业应用集成环境，从而明确了s-ESB在构建企业应用集成中的地位和作用；其次，提出了s-ESB的体系结构模型，并解决了协议适配，服务适配和公共服务等关键技术问题；最后，原型系统证明s-ESB的灵活性，可有效集成各类异构企业应用。

Research and implement of SOA-oriented enterprise services bus

For the quickly growing requirements of information sharing and business integration in enterprise, it tends to use SOA architecture to integrate enterprise applications because enterprise service bus can shield the heterogeneous enterprise applications. Current products of SOA-oriented Enterprise Service Bus (s-ESB) can mainly offer Web services container but unified adapter mechanism to integrate some kinds of enterprise applications. It restricts the availability and scalability of s-ESB. In this paper, it firstly brought forward a new SOA-based enterprise application integration environment which clarified the status and function of s-ESB in constructing Web services-based application supporting platform. Then, it presented an architecture for s-ESB, and then analyzed some key technologies including protocols adaptation, service adaptation and common services etc. At last, s-ESB is proved to be feasible and effective by prototype system.
