前言

根据权限管理系统引入，引出Shiro框架的配置和使用

一、权限管理系统

1.简介：

权限管理系统主要应用于系统的安全方面

1、前端用户交互的系统业务安全没有漏洞的
例如对于邮件发送系统来说：要对.sh .bat .exe 后缀的文件进行参数校验以防止漏洞
2、后台用户(管理员-非开发人员) 数据安全性
当具有这个权限的管理员才能进行这个相关的操作，吐过没有权限则不能进行操作和显示菜单
3、这时候后，为了管理这个就有了RBAC(Role-Based Access Control,基于角色的访问控制)，就是同坐角色于权限进行关联，简单来说就是一个用户拥有多个角色，每一个角色拥有若干的权限，构造成“用户-角色-权限”的授权模型。在这中模型中，用户与角色之间，角色与权限之间，一般都是多对多的关系，一个管理系统拥有多个权限。大概需要5个表，用户表，角色表，权限表，用户-角色表，角色-权限表。
4、希望达到的终极目的：页面中的功能没有权限的不可见；在地址栏拼写请求时将其拦截。
5、我们可以使用拦截器或者过滤器实现，但是那些又会显得特别麻烦，这时候我们就需要了简化它，所以有了框架——Shiro
6、需要创建的表：

2.Shrio框架

它是属于apache的一个安全框架

subject:主题，可以使用户也可以是程序。主体要访问系统，系统需要对主题进行认证授权。
securityManger:安全管理器，主体进行认证和授权都是同各国securityManager进行。
authenticator：认证器，主体进行认证最红通过authenticator进行的。执行登录操作（认证）登录用户名和密码
authorizeer:授权器，主题尽心授权最终通过authorizer进行的。获取这个身份下的所属权限，授权：当用用户进行认证后，根据这个用户信息获取权限列表；鉴权：当用户要执行操作时，进行鉴权
sessionManager:web应用中一般是用web容器对session进行管理，shiro页提供一台session管理的方式。
cacheManager:缓存管理器，主要对session和授权数据进行缓存，比如将授权数据通过cacheManager进行缓存管理，和cache整合对缓存数据进行管理。
作用：一个用户只有在登录后进行操作后才会查询数据库获取权限列表缓存，以后访问不会在访问，但是加入这个用户具备角色的管理，对自身拥有的角色进行了权限的更改后不会立即生效。

二、相关配置文件
