一直听说做权限将登陆信息放在session中，实际也说不太出个所以然来，幸运在工作当中接触到了对应的代码的copy。
实现思路：
类似于粗粒度的权限控制
将权限控制的文件按包分隔好，对应的url前缀也遵照一些标准统一。
定义包装用户信息类，包括登录后的用户信息和登录状态，用户授权信息等
使用过滤器，拦截通用请求、登录请求之外的所有请求。
过滤器中进行session中包装用户信息类是否存在，是否登录，如果有且有效则跳转对应页面，无则跳转登录页面
登录完成在session中写入用户的具体信息，包括登录状况和授权信息。
权限菜单的控制体现在入口，入口在前端显示的可操作菜单中只会有用户被授权的部分。利用z-tree类似组件取得用户权限和所有菜单的交集。
