    Handel Exception 

    @ControllerAdvice
@RestController
@Slf4j
public class ExceptionHandler extends ResponseEntityExceptionHandler {
    @Override
    protected ResponseEntity handleMethodArgumentNotValid(MethodArgumentNotValidException ex, HttpHeaders headers, HttpStatus status, WebRequest request) {
        List errorList = ex
                .getBindingResult()
                .getFieldErrors()
                .stream()
                .map(fieldError -> fieldError.getDefaultMessage())
                .collect(Collectors.toList());
        ErrorDetails errorDetails = new ErrorDetails(HttpStatus.BAD_REQUEST, ex.getLocalizedMessage(), errorList);
        return handleExceptionInternal(ex, errorDetails, headers, errorDetails.getStatus(), request);
    }
}
        }



    Customize Error Message
    


    @Data
public class ErrorDetails {
    private HttpStatus status;
    private String message;
    private List errors;

    public ErrorDetails(HttpStatus status, String message, List errors) {
        super();
        this.status = status;
        this.message = message;
        this.errors = errors;
    }

    public ErrorDetails(HttpStatus status, String message, String error) {
        super();
        this.status = status;
        this.message = message;
        errors = Arrays.asList(error);
    }
}
