Base on this we give out the basic architecture of the Service Gateway which is the key module in ESB. The main functions and operation flows of ESB are described, and then a realization based on JAVA platform is given out.

• 在此基础上设计并实现了其中最重要的服务网关(Service Gateway)模块,详细地描述了其基本架构、主要作用以及操作流程,给出了基于JAVA平台的一种具体实现方案。
