在类入口增加 @RestControllerAdvice注解。可以用于定义@ExceptionHandler、@InitBinder、@ModelAttribute，并应用到所有@RequestMapping、@PostMapping， @GetMapping注解中。

@RestControllerAdvice
@Slf4j
public class BizExceptionHandler {

    /**
     * 参数校验异常处理
     */
    @ResponseStatus(HttpStatus.OK)
    @ExceptionHandler(某某Exception.class)
    ResponseVO handleException(某某Exception exception) {

        return ResponseUtils.fail(exception.getUniteResponseCode(), exception.getMessage());

    }
}
