java - Sprint TestRestTemplate 返回 Id null

Question

我有一个 Spring 应用程序的集成测试，它使用 TestRestTemplate 发出请求。每次我发出请求时，模板都会返回一个实体，但 id 始终为空。如果我通过 Postman 执行相同操作，则 id 不为空，因此我必须与测试本身有关，但我不知道它是什么。有人有想法吗？

测试如下所示:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
@WebIntegrationTest(randomPort = true)
public class GameServiceControllerIT {
    @Value("${local.server.port}")
    private int port;

    private URL base;
    private RestTemplate template;

    @Before
    public void setUp()
            throws Exception {
        this.base = new URL("http://localhost:" + port + "/");
        this.template = new TestRestTemplate();
    }

    @Test
    public void testAddGame() {
        User user = addUser();
        ResponseEntity<Game> gameEntity = template.exchange(base + "/games/new?token=" + user.getToken(), HttpMethod.POST, null, Game.class);

        Assert.assertThat(gameEntity.getStatusCode(), is(HttpStatus.OK));               //This works
        Assert.assertThat(gameEntity.getBody().getOwner(), is(user.getUsername()));     //This works too
        Assert.assertThat(gameEntity.getBody().getId(), is(not(null)));                 //This doesn't work
    }

API 端点如下所示:

@RequestMapping(value = CONTEXT + "/new", method = RequestMethod.POST)
@ResponseBody
@JsonView(Views.Public.class)
public ResponseEntity<Game> createGame(@RequestParam("token") String token) {

    Game game = new Game();
    User owner = userRepo.findByToken(token);

    if (owner == null) {
        return new ResponseEntity<>(HttpStatus.NOT_FOUND);
    }

    if (!UserUtils.isInOpenGame(owner)) {
        owner.setCharacterType(CharacterType.CHEYENNE);
        game.setOwner(owner.getUsername());
        game.setStatus(GameStatus.PENDING);
        game.setCurrentPlayer(0);
        game.getPlayers().add(owner);
        game = gameRepo.save(game);

        logger.info("Game " + game.getId() + " successfully created");
        return ResponseEntity.ok(game);
    } else if (owner.getGames().size() > 0) {
        logger.info("User already created or joined a game");
        return new ResponseEntity<>(HttpStatus.PRECONDITION_REQUIRED);
    } else {
        return new ResponseEntity<>(HttpStatus.INTERNAL_SERVER_ERROR);
    }
}

我发现了同样的问题。不知何故，“Id”字段对于 RestTemplate 具有某种意义，因此它变为“保留”。如果您有权访问生成响应的服务器，只需将 Game 类中的字段名称更改为“Iid”即可。 getter getId() 必须重命名为 getIid()。
