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@Slf4jpublic 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());      resultVO.setStatus(ResponseCodeEnum.RETURN_STATUS_SUCCESS.getCode());      resultVO.setData(data);      return resultVO;   }

   public static <T>ResponseVO<T> success(Integer code, String msg , T data) {

      ResponseVO<T> resultVO = new ResponseVO<T>();      resultVO.setCode(code+"");      resultVO.setMessage(msg);      resultVO.setStatus(ResponseCodeEnum.RETURN_STATUS_SUCCESS.getCode());      resultVO.setData(data);      return resultVO;   }

   /**    *     * MethodName : fail    * @Description : 构建响应失败VO对象    */   public static <T>ResponseVO<T> fail() {      ResponseVO<T> resultVO = new ResponseVO<T>();      resultVO.setCode(ResponseCodeEnum.ERROR.getCode());      resultVO.setMessage(ResponseCodeEnum.ERROR.getMsg());      resultVO.setStatus(ResponseCodeEnum.RETURN_STATUS_FALSE.getCode());      return resultVO;   }

   /**    *     * MethodName : fail    *     * @Description : 自定义失败VO对象    * @param re    */   public static <T>ResponseVO<T> fail(ResponseCodeEnum re) {

      return fail(re, re.getMsg());   }

   /**    * Refactor of fail method    * @param re    * @param <T>    */   public static <T>ResponseVO<T> fail(UniteResponseCode re) {

      return fail(re, re.getMsg());   }

   /**    * Refactor of fail method    * @param re    * @param message    * @param <T>    */   public static <T>ResponseVO<T> fail(UniteResponseCode re, String message) {      ResponseVO<T> resultVO = new ResponseVO<T>();      resultVO.setCode(re.getCode());      resultVO.setMessage(message);      resultVO.setStatus(ResponseCodeEnum.RETURN_STATUS_FALSE.getCode());

      return resultVO;   }

   public static <T>ResponseVO<T> fail(Integer code, String message) {      ResponseVO<T> resultVO = new ResponseVO<T>();      resultVO.setCode(String.valueOf( code ));      resultVO.setMessage(message);      resultVO.setStatus(ResponseCodeEnum.RETURN_STATUS_FALSE.getCode());

      return resultVO;   }}
