一、简介

Version
Java17
SpringCloud2023.0.0
SpringBoot3.2.1
Spring Authorization Server1.2.1
Spring Security6.2.1
mysql8.2.0

Spring Authorization Server 使用JWT时，前两部分默认格式如下

{
  "kid": "33bd1cad-62a6-4415-89a6-c2c816f3d3b1",
  "alg": "RS256"
}
{
  "sub": "XcWebApp",
  "aud": "XcWebApp",
  "nbf": 1707373072,
  "iss": "http://localhost:63070/auth",
  "exp": 1707380272,
  "iat": 1707373072,
  "jti": "62e885c5-6b3f-49a2-aa10-b2e872a52b33"
}

现在我们要把用户信息也扩展到JWT，最简便的方法就是将用户信息写成JSON字符串替换sub字段。其中用户信息由xc_user数据库表存储。

二、重写UserDetailsService

注释掉原来的UserDetailsService实例。新建一个实现类，如下

@Component
@Slf4j
public class UserServiceImpl implements UserDetailsService {
    @Autowired
    XcUserMapper xcUserMapper;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        //根据username查询数据库
        XcUser xcUser = xcUserMapper.selectOne(new LambdaQueryWrapper<XcUser>()
                .eq(XcUser::getUsername, username));
        //用户不存在，返回null
        if (xcUser == null){
            return null;
        }
        //用户存在，拿到密码，封装成UserDetails,密码对比由框架进行
        String password = xcUser.getPassword();
        //扩展用户信息
        xcUser.setPassword(null);
        String userInfo = JSON.toJSONString(xcUser);
        UserDetails userDetails = User.withUsername(userInfo).password(password).authorities("read").build();
        return userDetails;
    }
}
  • 如果XcUser为null，返回null，这里处理了用户不存在的情况。
  • 如果用户存在，则获取密码，放到UserDetails 中，密码比对过程我们不关心，由框架完成。如果使用了加密算法，这里的password应该是密文。
  • 我们可以把用户信息转成JSON字符串放入withUsername。这样框架生成JWT时就会把用户信息也放进去。

是的，你没有猜错，UserDetails 只要返回密码框架就能比对成功，不需要再返回username。

三、Controller解析JWT获取用户信息

写一个工具类，通过Security ContextHolder.getContext()上下文获取Authentication然后解析JWT。

@Slf4j
public class SecurityUtil {
    public static XcUser getUser(){
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        if (authentication instanceof JwtAuthenticationToken) {
            JwtAuthenticationToken jwtAuth = (JwtAuthenticationToken) authentication;
            Map<String, Object> tokenAttributes = jwtAuth.getTokenAttributes();
            Object sub = tokenAttributes.get("sub");
            return JSON.parseObject(sub.toString(), XcUser.class);
        }
        return null;
    }
    @Data
    public static class XcUser implements Serializable {
    	//...
    }
}

JwtAuthenticationToken是Spring Authorization Server的一个类，可以帮助我们解析JWT。

四、后记

从SecurityContextHolder.getContext().getAuthentication()解析我们放进去的XcUser的方法不止一种，将其打印出来就可以看出，有多个地方包含了XcUser，例如。
