企业里大量Web应用系统是基于MVC Web框架开发的,为解决这些Web应用在门户中的集成问题,提出了一种面向MVC Web框架的Portlet桥接.该桥接分析了MVC Web框架和Portlet的运行机制以及二者的关联性,总结并试图解决桥接过程中的3个关键问题:请求处理、URL地址改写以及运行环境上下文的适配,最后给出了具体桥接的实现.结合应用案例,在不修改原来应用系统的情况下,Portlet桥接将其转换为Portlet无缝集成到门户中,提高了已有Web应用系统的重用性,说明了该桥接的有效性.%Quantities of web application in enterprise are developed based on the development of MVC web framework. To integrate these web applications into portal, a portlet bridge framework to support MVC web framework is proposed. The portlet bridge analyses the relation between MVC web framework and portlet, then summarizes and try to solve three key problems: request handling, URL rewriting and the adapting of context. Finally, the implementation is provided. Without source code being modified, web applications could be integrated into portal through the bridge, which improves the reusability of legacy systems. Meanwhile the efficiency of the Portlet bridge is demonstrated.
