会话外观模式在业务逻辑集成中的应用

Application of Session Facade Pattern in Business Logic Integration

在J2EE应用系统中会话外观模式应用在企业应用集成的业务逻辑集成层中,可以有效地解决随着客户端和服务器端之间的交互增加,而导致系统整体网络性能大幅下降的问题。通过会话外观模式来对业务组件调用,这样虚拟组件层管理着大量业务组件之间的交互,从而完成对业务逻辑的重新整合,它同时向客户端提供高度统一、透明的接口以简化客户端的调用。通过系统测试,表明在企业应用集成中应用会话外观模式后,应用服务器对来自客户端请求的响应时间将大大缩短,本次测试中该性能指标提高将近41.8%。

In a J2EE application system, the session facade pattern can be used in the enterprise application integrationof tile business logic integration layer to effectively solve the problem of a dramatic loss of overall system of network performance with the increased interaction between client and server. This paper uses the session facade pattern for the business component invocations, and the virtual component layer manages the interaction between a large number of business components so as to complete a new integrationof the business logic. At the same time, it provides highly uniform and transparent interface to simplify the client call. The system test result shows that, after using a session facade pattern in enterprise application integration, the application server responses to the request from the client will greatly shorten the response time which improved by approx 41.8%.
