基于J2EE体系的Web应用框架整合

Web Application Framework Composition Based on J2EE

在研究了大量流行的Web应用框架的基础上,提出了一种Web应用框架整合模型,即WAFC模型(Web Application Framework Composition),该模型基于分层思想,结合设计模式方法,给出了一组约束,增加了域对象层、服务定位层和数据接口层,有效地解决了框架整合过程中出现的功能冗余、层间通信不便、耦合度太高等问题。该模型充分挖掘了各个框架的长处,使它们以一种松散耦合方式结合,形成一个更高层次的应用框架。此外还结合了具体实例,分析和探讨了该模型的实例化过程。

This paper gives a model of Web application framework composition on the base of research of many popular Web application frameworks. It is called WAFC model. It is based on layer architecture, combines with design pattern, gives a set of restrictions, and introduces three new layers which are domain object layer, service locator layer and data access interface layer. The model solves the problems such as function redundancy, inconvenience of layer communication and tight coupling in the process nf frameworks composition. The model makes full use of strongpoint of each Web application framework, and combines them to achieve loose coupling. In addition, this paper discusses the process of instantiating the model with an example.
