SpringBoot集成整合JWT与Shiro流程详解
作者:leo825...
安全管理是软件系统必不可少的的功能。根据经典的“墨菲定律”——凡是可能,总会发生。如果系统存在安全隐患,最终必然会出现问题,这篇文章主要介绍了SpringBoot集成JWT、Shiro框架的使用
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。
实战演练
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 com.demo.common.Result; import com.demo.model.User; import com.demo.service.UserService; import com.demo.util.JwtUtil; import lombok.extern.slf4j.Slf4j; import org.apache.shiro.SecurityUtils; import org.apache.shiro.authz.UnauthorizedException; import org.apache.shiro.authz.annotation.Logical; import org.apache.shiro.authz.annotation.RequiresAuthentication; import org.apache.shiro.authz.annotation.RequiresPermissions; 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 { User user = userService.getUser(username); if (user.getPassword().equals(password)) { return new Result(200, "Login success", JwtUtil.sign(username, password)); } 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") @RequiresPermissions(logical = Logical.AND, value = {"view", "edit"}) public Result requirePermission() { return new Result(200, "You are visiting permission require edit,view", null); } @RequestMapping(path = "/401") @ResponseStatus(HttpStatus.UNAUTHORIZED) public Result unauthorized() { return new Result(401, "Unauthorized", null); } }
