权限分为五个表

注解式开发

常用注解介绍

  @RequiresAuthenthentication:表示当前Subject已经通过login进行身份验证;即 Subject.isAuthenticated()返回 true
  @RequiresUser:表示当前Subject已经身份验证或者通过记住我登录的
  @RequiresGuest:表示当前Subject没有身份验证或者通过记住我登录过，即是游客身份
  @RequiresRoles(value = {"admin","user"},logical = Logical.AND):表示当前Subject需要角色admin和user
  @RequiresPermissions(value = {"user:delete","user:b"},logical = Logical.OR):表示当前Subject需要权限user:delete或者user:b

需要在springMVC中使用shiro注解，所以需要把我们的securityManager安全管理器和我们的错误信息处理交给springMVC来管，所以就需要把它们配置进入spring-MVC.xml中

zs只能查看身份认证的按钮内容 其他的不能

ls、ww可以看权限认证按钮内容

zdm可以看所有按钮的内容
