总结一下：首先搭建好环境是关键：springboot–》MVC–》mybatis，然后进行shiro的过滤，认证，授权。。。
主要理解好
ShiroConfig
ShiroFilterFactoryBean
setFilterChainDefinitionMap（）
DefaultWebSecurityManager
自定义域 UserRealm 继承 AuthorizingRealm
AuthorizationInfo SimpleAuthenticationInfo
AuthenticationInfo SimpleAuthorizationInfo
UsernamePasswordToken
SecurityUtils
getSession()
getSubject()
getPrincipal()
AuthenticationToken。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。
