springboot+shiro+mybatis实现角色权限控制

# 背景 #

spring+spirngmvc+shiro的整合已经有很多了，之前的项目中也用过，但是最近想在springboot中使用shiro这样，其他项目需要的时候只需要把它依赖进来就可以直接使用，至于shiro的原理其他的blog都有很多介绍。这里只讲几个重点在项目中注意的地方。  
shiro官网  
[http://shiro.apache.org/][http_shiro.apache.org]

# shiro配置中重要的几个文件 #

![这里写图片描述][SouthEast]

其实最重要的就是shiro配置文件  
ShiroConfiguration.java：shiro启动时候的初始化工作，比如哪些是需要认证，哪些不需要认证；缓存配置设置；shiro权限数据在页面展示时整合需要的模板套件配置，等等。

ShiroRealm.java：shiro权限认证的具体实现代码，因为shiro本身只提供拦截路由，而具体如何数据源则由用户自己提供，不同的项目不同的要求，要不要加缓存登陆验证次数，要不要密码加密设置其他具体方式，这些都由用户自己决定，而shiro只提供给用户权限验证的格式接口，通过用户提供的数据源shrio判断要不要给具体用户授权请求路径的判断。  
ShiroRealm 涉及到以下点：  
principal:主体，就是登陆的当前用户类型的数据实体  
credentials：凭证，用户的密码，具体加密方式用户自己实现，什么都不做就是原文

*  Roles：用户拥有的角色标识（角色名称，admin,account,customer\_service），字符串格式列表:用户拥有多个角色的可能
 *  Permissions：用户拥有的权限标识（每个权限唯一标识，比如主键或者权限唯一标识编码），字符串格式列表：用户拥有多个权限的可能

### 涉及到的两个方法 ###

*  doGetAuthenticationInfo  
    获取用户的权限信息，这是为下一步的授权做判断，获取当前用户的角色和这些角色所拥有的权限信息。
 *  doGetAuthorizationInfo  
    根据用户的权限信息做授权判断，这一步是以doGetAuthenticationInfo为基础的，只有在有用户信息后才能根据用户的角色和授权信息做判断是否给用户授权，因此这里的Roles和Permissions是用户的两个重点判断依据
