【摘要】 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.更多还原

【Abstract】 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.更多还原
