SpringBoot集成整合JWT与Shiro流程详解-编程学习网

前言

代码库：https://gitee.com/leo825/springboot-learning-parents.git

之前写过《SpringBoot集成Shiro框架》，最近看了JWT，正好两个整合一下，加深一下理解。

代码结构

SQL脚本

schema.sql

create table if not exists t_user (
	`id`            int  primary  key not null ,
	`username`      char (50) not null,
	`password`      char(50) not null,
	`role`          char(50) not null,
	`permission`    char(255) not null
) ;

data.sql

insert into t_user(id, username, password, role, permission) values (0,'smith','smith123','user','view');
insert into t_user(id, username, password, role, permission) values (1,'danny','danny123','admin','view,edit')

数据格式如下：

username	password	role	permission
smith	smith123	user	view
danny	danny123	admin	view,edit

TestController

URL	作用
/login	登入
/article	所有人都可以访问，但是用户与游客看到的内容不同
/require_auth	登入的用户才可以进行访问
/require_role	admin的角色用户才可以登入
/require_permission	拥有view和edit权限的用户才可以访问

测试代码如下：

package com.demo.controller;

import org.apache.shiro.authz.annotation.RequiresRoles;
import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.*;
import javax.security.sasl.AuthenticationException;
@Slf4j
@RestController
@RequestMapping("/jwt")
public class TestController {
    @Autowired
    private UserService userService;
    @PostMapping("/login")
    public Result login(@RequestParam("username") String username, @RequestParam("password") String password) throws AuthenticationException {

        } else {
            throw new UnauthorizedException();
        }
    }
    @GetMapping("/article")
    public Result article() {
        Subject subject = SecurityUtils.getSubject();
        if (subject.isAuthenticated()) {
            return new Result(200, "You are already logged in", null);
        } else {
            return new Result(200, "You are guest", null);
        }
    }
    @GetMapping("/require_auth")
    @RequiresAuthentication
    public Result requireAuth() {
        return new Result(200, "You are authenticated", null);
    }
    @GetMapping("/require_role")
    @RequiresRoles("admin")
    public Result requireRole() {
        return new Result(200, "You are visiting require_role", null);
    }
    @GetMapping("/require_permission")

    }
