摘要
在访问控制模型中,权限作为客体,是核心部分。一般情况,系统的权限数量较多,访问频繁,采用传统方式管理权限已经不太适应实际需要。根据XML文档树形层次表示数据的特点,权限数据采用XML文档存储,并且使用JDOM进行解析处理。在XML管理权限的基础上,利用缓存机制读取权限数据到内存中,使得权限资源"一次加载,持续使用",加快权限的读取、加载,提高系统性能。
In Access Control Model,permission as object to visit is core.Generally,there are lots of permissions in one system,and they are accessed frequently.Taking traditional way to manage permissions is not suitable for real demands.According to XML document＇s characters of representing data as tree,permission data is stored in XML file and resolved by JDOM.Based on organizing permissions by XML,cache mechanism is considered to read permission data into memory.So permission resource is ＂once loaded,continuously used＂.Cache mechanism speeds up permissions＇ reading,loading,and improves system performance.
