MVC模式中控制层的实现

复杂的WEB应用程序要求采用模型-视图-控制器(MVC)设计模式的思想,MVC将应用设计分为多层,减弱了业务逻辑接口和数据接口之间的耦合。本文给出了MVC在J2EE框架下的实现,重点提出了在实际工程当中采用两层控制器的具体实现方式。实践证明对于包含了大量关系复杂视图的应用,两层控制器的实现方式效果是很理想的。

Implementation of Controller- layer in MVC Pattern

Complicated WEB applications ask of the idea of model- view- controller(MVC) design pattern which divides the application into multiplayer and lowers the coupling between logical interface and data interface. This article presents the implementation under J2EE architecture, and especially focuses on the Controller- layer which is implemented by using two layers in practical project. It is proved that the way of using two layers is perfect in the application which involves many complicated- relation views.
