java 权限框架 ij配置Shiro

Shiro是一个Java平台的开源权限框架，用于认证和访问授权。具体来说，满足对如下元素的支持：
用户，角色，权限(仅仅是操作权限，数据权限必须与业务需求紧密结合)，资源(url)。
用户分配角色，角色定义权限。
访问授权时支持角色或者权限，并且支持多级的权限定义。
在Shiro 中有三个核心组件：Subject ,SecurityManager , Realm
Subject 本质上就是当前访问用户的抽象描述。
SecurityManager 是Shiro架构中最核心的组件，通过它可以协调其他组件完成用户认证和授权。实际上，SecurityManager就是Shiro框架的控制器。
