2.Shiro的注解式开发

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

Controller层

ShiroController

package com.hmj.ssm.controller;

import org.apache.shiro.authz.annotation.Logical;
import org.apache.shiro.authz.annotation.RequiresPermissions;
import org.apache.shiro.authz.annotation.RequiresRoles;
import org.apache.shiro.authz.annotation.RequiresUser;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * @author 小何吖
 * @create 2022-08-26 20:03
 */
@Controller
@RequestMapping("/shiro")
public class ShiroController {

//    RequiresUser代表，当前方法只有登录后才能访问
//    RequiresUser 等价于 spring-shiro.xml中的user/updatePwd.jsp配置
    @RequiresUser
    @RequestMapping("/passUser")
    public String passUser(){
        System.out.println("身份认证通过");
        return "admin/addUser";

    }

//    RequiresRoles 代表 当前方法只有 具备指定的角色 才能够访问
//    RequiresUser 等价于 spring-shiro.xml中的user/updatePwd.jsp配置
    @RequiresRoles(value = {"1","4"},logical = Logical.AND)
    @RequestMapping("/passRole")
    public String passRole(){
        System.out.println("角色认证通过");
        return "admin/addUser";

    }

    //    RequiresPermissions 代表 当前方法只有 具备指定的角色 才能够访问
//    RequiresPermissions 等价于 spring-shiro.xml中的user/teacher.jsp=perms[2]配置
    @RequiresPermissions(value = {"2"},logical = Logical.AND)
    @RequestMapping("/passPermission")
    public String passPermission(){
        System.out.println("权限认证通过");
        return "admin/addUser";

    }

}
