门户集成Struts应用的Portlet化模型研究

Research on model of turning a Struts application into a Portlet during portal integration

在最少改变编码的前提下,将现有运行良好的应用系统移植到门户中是门户集成所面临的首要问题.针对门户构建中基于Struts框架的Web应用集成,分析了Struts框架和Portlet运行机制及二者的关联性,提出了一个Struts应用的Portlet化模型,并实现该模型.实例证明遵循Struts标准的应用均可以利用该模型实现为Portlet,作为组件集成到门户中,从而有效地提高了现有系统的可重用性.

The primary issue of portal integration is migrating an existing application to the portal on the condition of modifying the source code as less as possible. Focusing on the issue that how to integrate a Web application based on Struts framework into the portal, the operational mechanism of the Struts framework and Portlet and the relationship between them are analyzed. Then a model, which can turn an existing Struts application into a Portlet, is proposed and implemented. It is proved that an application based on Struts standards can be turned into a Portlet with the model, and the Portlet can be integrated into the portal as a component, thus reusing ability of the existing systems is improved effectively.
