/*shiro的注册，springboot没有配置文件，只有通过java类的形式进行注册，
关于shiro一共用 普通java类，SSM框架，springboot分别写了三遍，原理大致是一样的。区别在于怎么配置
1.shiro过滤器，  对登录的用户进行 认证，授权。对url路径进行的拦截，需要shiro过滤器
2.shiro管理器，管理认证 授权 缓存 等等。但是都需要创建配置。首先创建安全管理器，去管理各种组件。
3.shiro自定义域。shiro安全管理器中认证需要的组件
4.密码匹配器。
5.缓存
6.使shiro权限注解生效
7.对类进行aop代理
8.对thymeleaf进行支持

//在html标签中做一下声明，这个HTML页面为thymeleaf ，并且可以使用 shiro标签
