spring统一错误响应设置

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());

    }
}

响应工具类：

public class ResponseUtils {

   /**
    * 
    * MethodName : success
    * @Description : 构建响应成功对象
    * @return
    */
   public static <T>ResponseVO<T> success() {
      ResponseVO<T> resultVO = new ResponseVO<T>();
      resultVO.setCode(ResponseCodeEnum.SUCCESS.getCode());
      resultVO.setMessage(ResponseCodeEnum.SUCCESS.getMsg());
      resultVO.setStatus(ResponseCodeEnum.RETURN_STATUS_SUCCESS.getCode());
      return resultVO;
   }

   /**
    * 
    * MethodName : success
    * 
    * @Description : 构建响应成功VO对象
    * @param data
    */
   public static <T>ResponseVO<T> success(T data) {

      ResponseVO<T> resultVO = new ResponseVO<T>();
      resultVO.setCode(ResponseCodeEnum.SUCCESS.getCode());
      resultVO.setMessage(ResponseCodeEnum.SUCCESS.getMsg());
