我正在尝试使用@ControllerAdvice处理MethodArgumentNotValidException作为下面给出的代码:

@ControllerAdvice
public class RestResponseEntityExceptionHandler extends ResponseEntityExceptionHandler {

    private Logger log = LoggerFactory.getLogger(RestResponseEntityExceptionHandler.class);

    @Autowired
    private ApplicationContext applicationContext;

    @ExceptionHandler({ ConstraintViolationException.class })
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ResponseBody
    public ErrorWrapper handleConstraintViolationException(ConstraintViolationException e) {
        String fieldName = e.getConstraintName();
        String message = getResourceMessage(fieldName + ".alreadyExists", "Already Exists");
        return new ErrorWrapper(fieldName + ".error", message);
    }

    @ExceptionHandler({ MethodArgumentNotValidException.class })
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ResponseBody
    public ErrorWrapper handleMethodArgumentNotValidException(MethodArgumentNotValidException e) {
        return new ErrorWrapper(".error", "test");
    }

    private String getResourceMessage(String key, String defaultMessage) {
        String message = applicationContext.getMessage(key, null, Locale.getDefault());
        if (StringUtils.isNotEmpty(message)) {
            return message;
        } …
