参数化类型必须与构造函数中传递的对象相同。你用 ErrorDetails 所以你必须使用它：

@ControllerAdvice
public class GlobalExceptionHandler {

    // handling specific exception
    @ExceptionHandler(InvalidFieldException.class)
    public ResponseEntity<ErrorDetails> resourceNotFoundHandling(InvalidFieldException exception, WebRequest request){
        ErrorDetails errorDetails =
                new ErrorDetails(new Date(), HttpStatus.BAD_REQUEST, "Argument Validation failed", exception.getMessage(), request.getDescription(false));
        return new ResponseEntity<>(errorDetails, HttpStatus.BAD_REQUEST);
    }

    // handling global exception
    @ExceptionHandler(Exception.class)
    public ResponseEntity<ErrorDetails> globalExceptionHandling(Exception exception, WebRequest request){
        ErrorDetails errorDetails =
                new ErrorDetails(new Date(), HttpStatus.INTERNAL_SERVER_ERROR, "Global Exception", exception.getMessage(), request.getDescription(false));
        return new ResponseEntity<>(errorDetails, HttpStatus.INTERNAL_SERVER_ERROR);
    }
}
