面对日益复杂的Web应用系统和变更频繁的用户需求，企业需要从纷繁复杂的开发框架中选出一套可行的解决方案以保持高效保质的开发工作，为此，本文采用J2EE分层架构思想构建了一个面向Web应用系统快速开发的开发平台，其中，平台表现层采用Ember．js对JSP局部页面进行异步刷新，控制层由Spring MVC实现，业务层以Spring Framework为基础集成Activiti流程引擎和Velocity模板引擎，持久层由JPA负责完成与数据库的交互。实践证明，采用该开发平台构建的Web应用系统均具有层次间耦合度低、模块复用性高等特点，大大提高了开发的效率，有效降低了开发和维护的成本。%In the face of increasingly complex Web application systems and frequently changed user requirements, the enterprises need to choose a feasible solution form numerous and complicated development frameworks so as to maintain high efficiency and quality of development work. For this purpose, this paper constructs a development platform for rapid development of Web application systems based on J2EE layered architecture. In presentation layer, Ember.js is implemented asynchronous refresh on partial page of JSP. In control layer, it is achieved with Spring MVC. In business layer, Activiti process engine and Velocity template engine are integrated on the basis of Spring Framework. In persistence layer, JPA is adopted to implement interactive with databases. It has been proved that the Web application systems constructed form the development platform have the characteristics of low coupling degree between layers and high reusability for modules, which improve the development efficiency and reduce the cost of development and maintenance greatly.
