如何在Spring Boot应用程序中使用Hibernate Validation进行Bean验证？

您要么必须创建一个

ControllerAdvice

MethodArgumentNotValidException

    @ResponseStatus(BAD_REQUEST)    @ResponseBody    @ExceptionHandler(MethodArgumentNotValidException.class)    public CustomError methodArgumentNotValidException(MethodArgumentNotValidException ex) {        BindingResult result = ex.getBindingResult();        List<org.springframework.validation.FieldError> fieldErrors = result.getFieldErrors();        return mapToCustomError(fieldErrors);    }

或者，您可以注入

BindingResult

    @PostMapping("/ibantoiban")    public ResponseEntity<String> sendMoneyIbanToIban(@Valid @RequestBody IbanToIbanRequest ibanToIbanRequest, BindingResult bindingResult) {        if (bindingResult.hasErrors()) {  }        Transaction transaction = transactionService.sendMoneyIbanToIban(ibanToIbanRequest);        HttpHeaders headers = new HttpHeaders();        headers.add("Location", "/ibantoiban" + transaction.getTransactionId().toString());        return new ResponseEntity(headers, HttpStatus.CREATED);    }
