一、shiro授权角色、权限

                UserMapper.xml

<select id="queryByroleid" resultType="java.lang.String" parameterType="java.lang.String">
   select roleid FROM t_shiro_user us,t_shiro_user_role usr
   where us.userid = usr.userid and us.username = #{userName}
  select>
 
  <select id="queryByperid" resultType="java.lang.String" parameterType="java.lang.String">
 select rp.perid from t_shiro_user u,t_shiro_user_role ur,t_shiro_role_permission rp
  where rp.roleid = ur.roleid and u.userid = ur.userid and u.username = #{userName}
  select>

        UserMapper

   Set queryByroleid(@Param("userName") String userName);
 
    Set queryByperid(@Param("userName") String userName);

      重写  MyRealm 中的 AuthorizationInfo 方法

 @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        String userName = principals.getPrimaryPrincipal().toString();
        Set roleid = userBiz.queryByroleid(userName);
        Set perid = userBiz.queryByperid(userName);
        SimpleAuthorizationInfo info =new SimpleAuthorizationInfo();
        info.setStringPermissions(perid);
        info.setRoles(roleid);
        return info;
    }

二、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
