我有一个ConstraintViolationException如下所示的处理程序类：

@Produces
@Singleton
@Requires(classes = {ConstraintViolationException.class, ExceptionHandler.class})
public class ConstraintsViolationsExceptionHandler
        implements ExceptionHandler<ConstraintViolationException, HttpResponse> {

    @Override
    public HttpResponse
    handle(HttpRequest request, ConstraintViolationException exception) {
        return HttpResponse
                .status(HttpStatus.FORBIDDEN)
                .contentType(MediaType.APPLICATION_JSON)
                .characterEncoding("UTF-8")
                .body(new SignUpPhoneNumberErrorResponse<>(400,
                        "Wrong data used",
                        new ArrayList<>(exception.getConstraintViolations())));
    }
}  

我的错误处理 POJO 在哪里SignUpPhoneNumberErrorResponse，它被序列化为 JSON 绝对没问题。

我的控制器看起来像这样：

@Controller(PhoneAuthAndLoginConstants.CONTROLLER_BASE_PATH)
@Validated
public class UserPhoneNumberRegistrationAndLoginController {

    @Inject
    MongoDbUserSignUpPhoneNumberDAO mongoDbUserSignUpPhoneNumberDAO;

    @Post(uri = PhoneAuthAndLoginConstants.CONTROLLER_SIGN_UP_PATH,
            consumes = MediaType.APPLICATION_JSON,
            produces = MediaType.APPLICATION_JSON)
    public Single<ResponseDataEncapsulate>
    signUpForPhoneVerification(@Valid @Body UserSignUpPhoneNumberEntity phoneNumber) {
        return mongoDbUserSignUpPhoneNumberDAO.sendVerification(phoneNumber);
    }

    @Post(uri = PhoneAuthAndLoginConstants.CONTROLLER_SIGN_UP_PATH
            +
            PhoneAuthAndLoginConstants.CONTROLLER_SIGN_UP_VERIFICATION_CODE_PARAM,
            consumes …
