@ControllerAdvice
public class GlobalExceptionHandler {

    @ExceptionHandler(MethodArgumentNotValidException.class)
    public ResponseEntity<Object> handleMethodArgumentNotValid(MethodArgumentNotValidException ex) {
        // 异常处理逻辑

    }
    ErrorResponse response = new ErrorResponse("Invalid request", errors);
    return new ResponseEntity<>(response, HttpStatus.BAD_REQUEST);
}

public class ErrorResponse {
    private String message;
    private List<String> errors;

    // 构造方法、getter和setter方法省略
