| 摘 要： | 传统的MVC模式在表示层和业务逻辑层存在大量的数据交换,降低了系统的效率,讨论了在软件开发过程中具体存在的问题,分析了Session Faade和Business Delegate两种设计模式的特点,提出将这2种模式和MVC模式结合,形成完善的J2EE开发模式.同时,对J2EE架构中的数据持久层进行分析和改进,提出用DAO类和DAOFactory类实现数据持久层的方法,形成更完善的J2EE体系结构.

| Abstract: | There are lots of data exchanges between presentation layer and logic layer in MVC pattern, and the system efficiency is reduced. This paper discusses the problem in software development, ana- lyses the peculiarity of Session Facade and Business Delegate, advances a new MVC design pattern by combining the Session Facade and Business Delegate. It also designs the data persistence object, proposed a method to implements data persistence object, and finishes a perfect J2EE development Architecture. |
