Spring Security前后分离校验token的实现方法

作者：专注写bug

这篇文章主要介绍了Spring Security前后分离校验token的方法，本次token生成采取jwt的方式，通过引入jwt依赖文件配置token管理器,对Spring Security校验token相关知识感兴趣的朋友一起看看吧

前言

之前采取项目中嵌套html页面，实现基本的登录校验、权限校验、登出操作、记住我等功能试下。

但是，现在的开发基本都是前后分离样式，后端并不需要配置登录页的操作。

如何才能做到前后分离，同时也能支持登录和token校验呢，本篇博客详细说明。

token配置

本次token生成采取jwt的方式。

引入JWT依赖文件

<dependency>
  <groupId>com.auth0</groupId>
    <artifactId>java-jwt</artifactId>
    <version>3.10.3</version>
</dependency>

配置token管理器类

自定一个Token生成和从token中解析用户名的一个类，并交给Spring管理。

package security.config;

import com.auth0.jwt.JWT;
import com.auth0.jwt.JWTVerifier;
import com.auth0.jwt.algorithms.Algorithm;
import com.auth0.jwt.interfaces.Claim;
import com.auth0.jwt.interfaces.DecodedJWT;
import org.springframework.stereotype.Component;
import java.util.Calendar;
import java.util.HashMap;
@Component
public class TokenJwtManager {
    // 设置token时间
    private int tokenEcpiration = 24*60*60*1000; // 毫秒   24h
    // 编码密钥
    private String tokenSignKey = "123456";
    // 1、根据用户名生成token
    public String createToken(String userName){
        Calendar calendar = Calendar.getInstance();
        calendar.add(Calendar.SECOND, tokenEcpiration);
        String userName1 = JWT.create()
                .withHeader(new HashMap<>())
                .withClaim("userName", userName)
                .withExpiresAt(calendar.getTime()) // 过期时间
                .sign(Algorithm.HMAC256(tokenSignKey));// 签名
        return userName1;
    }
    // 2、根据token得到用户名信息
    public String getUserName(String token){
        JWTVerifier build = JWT.require(Algorithm.HMAC256(tokenSignKey)).build();
        DecodedJWT verify = build.verify(token);
        Claim userName = verify.getClaim("userName");
        return userName.asString();
    public static void main(String[] args) {
        String ss = new TokenJwtManager().createToken("1111111");
        System.out.println(ss);
        System.out.println(new TokenJwtManager().getUserName(ss));
}

security 配置

    @Override
    public void commence(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, AuthenticationException e) throws IOException, ServletException {
        log.info("======= commence ===");
        // 返回请求端
        Map<String,Object> resultMap = new HashMap<>();
        // 保存数据
        resultMap.put("code","10000");
        resultMap.put("msg","当前账户未登录");
        resultMap.put("data",new HashMap<>());
        // 设置返回消息类型
        httpServletResponse.setHeader("Content-type", "text/html;charset=UTF-8");
        httpServletResponse.setCharacterEncoding("utf-8");
        httpServletResponse.setContentType("application/json;charset=UTF-8");
        // 返回给请求端
        PrintWriter writer  = httpServletResponse.getWriter();
        writer.write(resultMap.toString());
        writer.close();
    }
}

配置无权限处理类

package security.config.handler;

import org.springframework.security.access.AccessDeniedException;

@Component  // 交给spring管理
public class MyAccessDeniedHandler implements AccessDeniedHandler {
    @Override
    public void handle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, AccessDeniedException e) throws IOException, ServletException {
        Map<String,Object> resultMap = new HashMap<>();
        // 保存数据
        resultMap.put("code","403");
        resultMap.put("msg","无权访问");
        resultMap.put("data",null);
        // 设置返回消息类型
        httpServletResponse.setHeader("Content-type", "text/html;charset=UTF-8");
        httpServletResponse.setCharacterEncoding("utf-8");
        httpServletResponse.setContentType("application/json;charset=UTF-8");
        // 返回给请求端
        PrintWriter writer = httpServletResponse.getWriter();

    @Override
    public void logout(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) {
        // 1、从header中获取token
        String token = httpServletRequest.getHeader("token");
        log.info("token信息为  {}",token);
        String userName = tokenJwtManager.getUserName(token);
        log.info("从token获取userName信息为  {}",token);
        // redis 移除登录信息等逻辑
        // xxxxx
        // 2、返回请求端
        Map<String,Object> resultMap = new HashMap<>();
        // 保存数据
        resultMap.put("code","200");
        resultMap.put("msg",userName+"登录成功");

            }
            return new UsernamePasswordAuthenticationToken(username,token,authority);
        return null;
}

自定义加密类

package security.config;

import lombok.extern.slf4j.Slf4j;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;
import security.utils.Md5Utils;
/**
 * 密码加密、比对

        return encodePwd.equalsIgnoreCase(Md5Utils.md5(charSequence.toString()));
}

配置UserDetailService

package security.service;

import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.AuthorityUtils;

import org.springframework.stereotype.Service;
import security.mapper.UserMapper;
import security.vo.SecurityUser;
import security.vo.User;
import java.util.Arrays;
import java.util.List;
/**
 * security 登录信息和权限获取类
 */
@Service("userDetailsService")
@Slf4j
public class UserDetailService implements UserDetailsService {
    // 注入Usermapper
    @Autowired
    private UserMapper userMapper;
    @Override
    public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException {
        log.info("====== loadUserByUsername ======");
        // 通过username查询数据库获取用户信息
        QueryWrapper<User> userQueryWrapper = new QueryWrapper<>();
        userQueryWrapper.eq("username",userName);
        User user = userMapper.selectOne(userQueryWrapper);
        // 判断用户是否存在
        if(user == null){
            throw new UsernameNotFoundException("账户信息不存在！");
        }
        // 存在对应的用户信息，则将其封装，丢给security自己去解析
        log.info("user:{}",user);
        // 权限暂时不查数据库
        List<String> admin = Arrays.asList("ROLE_user,ROLE_admin,admin");
        // 将数据封装给 SecurityUser ，因为 SecurityUser 是 UserDetails 的子类
        SecurityUser securityUser = new SecurityUser();
        securityUser.setPermissionValueList(admin);
        securityUser.setUser(user);
        log.info("securityUser:{}",securityUser.toString());
        return securityUser;
    }
}

配置数据库User对象映射类

package security.vo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.io.Serializable;
@Data
@NoArgsConstructor
@AllArgsConstructor
public class User implements Serializable {
    private static final long serialVersionUID = -5461108964440966122L;
    private Integer id;
    private String username;
    private String password;
    private Integer enabled;
    private Integer locked;
}

配置UserDetailService使用的SecurityUser类

package security.vo;

import lombok.Data;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.util.StringUtils;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
/**
 * UserDetailService 使用该类，该类必须是 UserDetails 的子类
 */
@Data
public class SecurityUser implements UserDetails {
    // 登录用户的基本信息
    private User user;
    //当前权限
    private List<String> permissionValueList;
    public SecurityUser() {
    }
    public SecurityUser(User user) {
        if (user != null) {
            this.user = user;
        }
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        Collection<GrantedAuthority> authorities = new ArrayList<>();
        permissionValueList.forEach(permission ->{
            if(!StringUtils.isEmpty(permission)){
                SimpleGrantedAuthority authority = new SimpleGrantedAuthority(permission);
                authorities.add(authority);
            }
        });
        return authorities;
    public String getPassword() {
        return user.getPassword();
    public String getUsername() {
        return user.getUsername();
    public boolean isAccountNonExpired() {
        return true;
    public boolean isAccountNonLocked() {
    public boolean isCredentialsNonExpired() {
    public boolean isEnabled() {
}

配置mybatis-plus

首先，需要配置application.properties数据库连接源。

spring.datasource.username=root
spring.datasource.password=root
spring.datasource.url=jdbc:mysql://106.55.137.66:3306/security?useSSL=false&useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

server.port=80

其次，需要配置Mapper类，查询数据库获取基本数据信息。

package security.mapper;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.springframework.stereotype.Repository;
import security.vo.User;
@Repository
public interface UserMapper extends BaseMapper<User> {
}

配置几个测试接口

package security.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class TestController {
    @RequestMapping("/test")
    public String test(){
        return "不需要认证就能访问";
    }
}
package security.controller;

import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class UserController {
    @RequestMapping("/user/test1")
    @PreAuthorize("hasAnyAuthority('admin','user')")
    public String test1(){
        return "需要认证的 /user/test1";
    }
    @RequestMapping("/user/test2")
    @PreAuthorize("hasAnyAuthority('test')")
    public String test2(){
        return "需要认证的 /user/test2";
}

Md5加密工具类

import java.io.UnsupportedEncodingException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

     * 传入文本内容，返回 SHA-512 串
    public static String SHA512(final String strText)

            }
            catch (NoSuchAlgorithmException e)
                e.printStackTrace();

测试

测试采取ApiPost 工具，让测试更接近前后分离。

首先测试登录

Post
localhost/user/login

账号密码有一个不对时。

数据库sql脚本

CREATE TABLE `user` (
  `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT, -- 主键
  `username` varchar(255) DEFAULT NULL,    -- 用户名
  `password` varchar(255) DEFAULT NULL,    -- 用户密码
  `enabled` tinyint(1) DEFAULT '1',        -- 是否启用 1-启用 0-未启用
  `locked` tinyint(1) DEFAULT '0',         -- 是否被锁 1-已锁 0-未锁
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

数据为：

insert INTO user(username,password,enabled,locked) VALUES("xiangjiaoSS","1babad058e03c5296a94a5a8d7d6dd8a",1,0); -- bunana 的md5 值
insert INTO user(username,password,enabled,locked) VALUES("xiangjiaoSS2","0b13310f8db2dc22e7ddd0cdc5f0a61a",1,0); -- bunana1 的md5 值
insert INTO user(username,password,enabled,locked) VALUES("xiangjiaoSS3","b3fbcd9c9d97e47f263a19a0e01efc7d",1,0); -- bunana2 的md5 值
