为什么我的Spring API响应中没有显示某些变量？

Question

我有一个spring控制器，让我登录，并应该在输入正确的凭据时返回用户详细信息（角色，用户名）作为响应，而只返回jwt令牌和用户名。这是api响应：

{

"username": "adam",

"token": "eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJhZGFtIiwicm9sZXMiOlsiUk9MRV9BRE1JTiJdLCJpYXQiOjE1NTcyMzUxMTMsImV4cCI6MTU1NzIzODcxM30.PksRTzgYu6r79KNmc4YDNXGqO1Ke63oOzzoPjURUY9k"

}

我的控制器：

package com.example.demo.controller;

import com.example.demo.domain.User;
import com.example.demo.repository.UserRepository;
import com.example.demo.security.jwt.JwtTokenProvider;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.ResponseEntity;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.BadCredentialsException;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.web.bind.annotation.*;

import java.util.HashMap;
import java.util.Map;

import static org.springframework.http.ResponseEntity.ok;

@RestController
@RequestMapping("/auth")
public class AuthController {

@Autowired
AuthenticationManager authenticationManager;

@Autowired
JwtTokenProvider jwtTokenProvider;

@Autowired
UserRepository users;

@PostMapping("/signin")
public ResponseEntity signin(@RequestBody User user) {

    try {
        String username = user.getUsername();
        authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(username, user.getPassword()));
        String token = jwtTokenProvider.createToken(username, this.users.findByUsername(username).orElseThrow(() -> new UsernameNotFoundException("Username " + username + "not found")).getRoles());

        Map<Object, Object> model = new HashMap<>();
        model.put("username", username);
        model.put("token", token);
        model.put("roles", user.getRoles());
        return ok(model);
    } catch (AuthenticationException e) {
        throw new BadCredentialsException("Invalid username/password supplied");
    }
}
}
