基于JSP/Servlet的权限系统的设计与实现

Design and Realization of Privilege System Based on JSP/Servlet

对用户访问权限的控制是B/S模式系统开发和应用的一个重要环节.通过对RBAC模型以及Servlet过滤器的分析研究,给出了用户权限判断和控制的方法,并采用4层架构技术设计和实现了一个权限管理系统,有效地实现了用户对系统的安全访问.此系统具有可维护性、可扩充性和可移植性等特性.

It is an important step to control the user＇s access privilege in application and development of B/ S system. Through the analysis of Role-based Access Control model and Servlet filter, a method of user privilege estimation and control was put forward. A privilege management system was designed and implemented with four-tier architecture technique, which efficiently realized the safety access of users. This system has performance of maintainability, extensibility and portability and so on.
