这是我的验证类，它实现了ConstraintValidator

@Slf4j
public class DocumentMetaDataValidation implements ConstraintValidator<DocumentMetaDataValidator, DocumentMetaDataApplicationRequest> {

    @Override
    public boolean isValid(DocumentMetaDataApplicationRequest dataApplicationRequest, ConstraintValidatorContext constraintValidatorContext) {

        constraintValidatorContext.disableDefaultConstraintViolation();
        if(!Objects.nonNull(dataApplicationRequest)) {
            log.error("Request Parameter is null/empty : ");
            constraintValidatorContext
                    .buildConstraintViolationWithTemplate("Required parameter DocumentMetaDataApplicationRequest cannot be null/empty")
                    .addConstraintViolation();
            return false;
        }
        Set<String> documentTypeSet=new HashSet<>();
        dataApplicationRequest.getDocumentDetails().stream().forEach(documentDetails ->
            documentTypeSet.add(documentDetails.getDocumentType()));

        if (documentTypeSet.size()!=dataApplicationRequest.getDocumentDetails().size()){
            log.error("Duplicate document type present ");
            constraintValidatorContext
                    .buildConstraintViolationWithTemplate("Duplicate document type present")
                    .addConstraintViolation();
            return false;
        }

        return true;
    }
}

这是我的控制器：

@PostMapping(path = "/{referenceId}")
  public Mono<DocumentUploadResponse> upload(
      @NotBlank(message = "reference Id cannot be blank")
      @PathVariable(value = "referenceId") String referenceId,
      @NotEmpty(message = "List should not be empty")
      @DocumentValidator @RequestPart(value = "documents") List<FilePart> document,
      @DocumentMetaDataValidator @Valid @NotNull(message = "DocumentMetadata cannot be null")
      @RequestPart(value = "documentsMetaData") DocumentMetaDataApplicationRequest documentMetaDataApplicationRequest) {

    log.info("inside DocumentStorageController : uploadDocument()");
    return documentStorageService.upload(referenceId, document, documentMetaDataApplicationRequest);

  }

这是我的验证器类

@Target( { FIELD, PARAMETER })
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Constraint(validatedBy = DocumentMetaDataValidation.class)
public @interface DocumentMetaDataValidator {
    public String message() default ErrorMessage.VALIDATION_ERROR;

    Class<?>[] groups() default {};

    Class<? extends Payload>[] payload() default {};
}

而不是得到错误为“重复的文档类型存在”im得到“上传.DocumentMetaDataApplicationRequest：其中upload是我的控制器中的方法，DocumentMetaDataApplicationRequest是我试图验证的类。
我试着浏览文档，似乎它附加了一个名为“propertyPath”的东西，我无法摆脱它。
