基于Portlet的个性化门户系统组装工具研究与实现

针对现有门户系统开发中缺乏流程控制,以及企业门户系统的更新维护费用高、开发速度慢等问题,文中提出了一个基于流程的企业门户信息系统参考模型,并基于此模型设计开发了一个基于portlet的门户系统组装工具,详细介绍了实现工具的体系结构、基于XML的构件封装方法、门户页面展现和组装等关键算法.利用该工具,用户可以方便的从portlet库中选择不同类型、不同功能的构件,通过点击或者拖拉的方式方便的组装企业门户系统,大大提高了开发效率.

The Research and Realization of Personalized Portal Assembly Tool Based on Portlet

To solve the problems of lack of process control in the development of existing portal system, high - cost in maintenance and long development circle in enterprise portal systems, in this paper, we propose a process - based enterprise portal information system model, and based on this model, we develop a system assembly tool using portlet and interpret the architecture of the tool in details, moreover the methods of XML- based component encapsulation and algorithms of page render and assembly are described. With this tool, user can select components of different types and different functions from portlet library conveniently. In addition, through click or drag, enterprise portal system can be easily assembled, thus the system development efficiency is greatly enhanced.
