在Micronaut中未执行ConstraintViolationException处理程序 [英] ConstraintViolationException handler isn't executed in Micronaut

问题描述

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

I have a ConstraintViolationException handler class that looks like this:

@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())));
    }
}  

其中 SignUpPhoneNumberErrorResponse 是我处理POJO的错误，它正被序列化为JSON完全正常.

where SignUpPhoneNumberErrorResponse is my error handling POJO which is getting serialized to JSON absolutely fine.

我的控制器看起来像这样:

My Controller looks like this:

@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 = MediaType.APPLICATION_JSON,
            produces = MediaType.APPLICATION_JSON)
    public Single<ResponseDataEncapsulate>
    sendUserSignUpConfirmation(@Valid @Body UserAccountStateSignUpEntity verificationData,
                               HttpHeaders httpHeaders) {
        return mongoDbUserSignUpPhoneNumberDAO.signUp(verificationData);
    }
}  

我的 UserAccountStateSignUpEntity 的POJO如下:

@Data
@NoArgsConstructor
@AllArgsConstructor
@JsonIgnoreProperties(ignoreUnknown = true)
public class UserAccountStateSignUpEntity implements UserSignUpEntity {
    @NotNull @NotBlank @Size(min = 5, max = 13) private String phoneNumber;
    @NotNull @NotBlank @Size(min = 7, max = 7) private String verificationCode;
    @JsonIgnore private Boolean verifiedAccount = Boolean.FALSE;

    public UserAccountStateSignUpEntity(String phoneNumber, String verificationCode) {
        this.phoneNumber = phoneNumber;
        this.verificationCode = verificationCode;
        this.verifiedAccount = Boolean.TRUE;
    }

    @Override
    public Map<String, Object> makePhoneEntityMapForMongo() {
        HashMap<String, Object> returnMap = new HashMap<String, Object>() {{
            put("phoneNumber", phoneNumber);
            put("verificationCode", verificationCode);
            put("verifiedAccount", verifiedAccount);
        }};

        return Collections.unmodifiableMap(returnMap);
    }
}  

我发送这样的请求有效负载:

I send in a request payload like this:

{
    "phoneNumber" : "91-123456789",
    "verificationCode" : "18887"
}  

这应该触发一个 ConstraintViolationException ，并且我的处理程序代码应该执行，并且我应该获得HTTP Forbidden.但是，相反，我得到了默认的HTTP Bad Request错误消息.

This should trigger a ConstraintViolationException and my handler code should execute and I should get a HTTP Forbidden. But instead I get the default HTTP Bad Request error message.

为什么我的处理程序没有被执行?如何使它执行?

我正在使用 Micronaut 1.1.3 作为Web框架，并使用 Hibernate Validator 作为 javax.validation 的实现.

I'm using Micronaut 1.1.3 as the web framework and the Hibernate Validator as the javax.validation implementation.

推荐答案

@Error可以应用于方法以将其映射到错误路由，并且在发生任何ConstraintViolationException时，SignUpPhoneNumberErrorResponse将作为错误响应主体返回.

@Error that can be applied to method to map it to an error route and SignUpPhoneNumberErrorResponse would be returned as a error response body when any ConstraintViolationException occured.

@Controller("/${path}")
@Validated
public class UserPhoneNumberRegistrationAndLoginController {

    @Post
    public HttpResponse method(@Valid @Body UserAccountStateSignUpEntity verificationData, HttpHeaders httpHeaders) {
        return null;
    }

    @Error(exception = ConstraintViolationException.class)
    public SignUpPhoneNumberErrorResponse onSavedFailed(HttpRequest request, ConstraintViolationException ex) {
        return new SignUpPhoneNumberErrorResponse(500,
                        "Wrong data used",
                        String.valueOf(ex.getConstraintViolations().stream().map( e -> e.getPropertyPath()+": "+e.getMessage()).collect(Collectors.toList())),
                "Application",
                "Error",
                System.currentTimeMillis());
    }

    @Error(status = HttpStatus.NOT_FOUND, global = true)  
    public HttpResponse notFound(HttpRequest request) {
        //return custom 404 error body
    }

}
