【摘要】 为了解决数字校园中越来越复杂的权限管理问题,通过对现有访问控制技术的分析,提出一种实现基于角色的访问控制方法.权限管理系统整体采用J2EE框架,用XML编写访问控制规则,利用规则对数据集从行、列和时间等3个方面进行访问控制,较好地适应了数字校园中各业务系统灵活多变的需要.更多还原

【Abstract】 In order to solving the problems caused by more and more complexity authorization in digital campus,three mainstream control technologies are analyzed and a new method to implement RBAC is proposed.Authorization management system takes J2EE as framework,uses XML to express access control rules.The rules control data in rows,cols and time is abstracted,which satisfies the flexible requirements in digital campus application systems.更多还原
