java - 响应内容类型为 'null' 。放心异常

Question

我很难放心。我收到以下错误

java.lang.IllegalStateException: Cannot parse object because no supported Content-Type was specified in response. Content-Type was 'null'.

我的休息 Controller 如下所示

@Slf4j
@RestController
@RequestMapping(ApiUrls.SESSIONS_API)
@RequiredArgsConstructor
public class SessionsApi {

    private final SessionsService sessionsService;

    @GetMapping(produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
    public List<SessionDto> sessions(@AuthenticationPrincipal CryptoUser user,
                                     @RequestParam(required = false, defaultValue = "false") boolean includeExpired) {
        log.info("User sessions of user [id {} username {}]", user.getUserId(), user.getUsername());


        return sessionsService.getSessionsOfUser(user, includeExpired);
    }

和测试

SessionDto[] sessionDtos = given().mockMvc(mvc)
        .log().all()
        .header("Accept","application/json")
        .get(ApiUrls.SESSIONS_API)
        .then()
        .extract()
        .as(SessionDto[].class);

是我得到的放心日志

Request method: GET
Request URI:    http://localhost:8080/api/sessions?includeExpired=true
Proxy:          <none>
Request params: includeExpired=true
Query params:   <none>
Form params:    <none>
Path params:    <none>
Headers:        Content-Type=application/json
                Accept=application/json
Cookies:        <none>
Multiparts:     <none>
Body:           <none>

我尝试在 getmapping 中添加 produces = MediaType.APPLICATION_JSON_VALUE 但无论如何都没有用。我错过了什么吗？线程甚至没有进入 Controller 方法

如果您的内容类型为空，您可以尝试这样的操作

given().mockMvc(mvc)
    .log().all()
    .header("Accept","application/json")
    .get(ApiUrls.SESSIONS_API)
    .then()
    .contentType(isEmptyOrNullString())//This is where you handle null
    .extract()
    .as(SessionDto[].class);
