请求类：

@Datapublic class ColumnUpdateDTO {    @NotNull(message = "字段id不能为空")    @ApiModelProperty(value = "字段id", required = true)    private Long id;    @ApiModelProperty(value = "字段中文名")    private String columnName;    @ApiModelProperty(value = "字段描述")    private String comment;}

Controller：

@PostMapping("/updateColumnInfos")    public ResponseEntity
   
     updateColumnInfos(            @RequestBody List
    
      columnUpdateDTOList) {        ResultResponse resultResponse = BindingResultUtils.checkListError(columnUpdateDTOList);        if (resultResponse.getCode() == HttpCodeEnum.FAIL.getCode()) {            return ResponseEntity.ok(resultResponse);        }        // 业务代码        return ResponseEntity.ok(new ResultResponse().success());    }
    
   

工具方法：

public static ResultResponse checkListError(List list) throws IllegalAccessException {        // 校验参数        if (CollectionUtils.isEmpty(list)) {            ResultResponse resultResponse = new ResultResponse().fail(HttpCodeEnum.FAIL.getCode(), "数组不能为空");            return resultResponse;        }        List
   
     errorMessage = new ArrayList<>();        for (int i = 0; i < list.size(); i++) {            Object object = list.get(i);            Field[] fields = object.getClass().getDeclaredFields();            for (Field field : fields) {                field.setAccessible(true);                NotNull notNull = field.getAnnotation(NotNull.class);                if (Objects.nonNull(notNull) && Objects.isNull(field.get(object))) {                    errorMessage.add("index[" + i + "]" + notNull.message());                }                NotBlank notBlank = field.getAnnotation(NotBlank.class);                if (Objects.nonNull(notBlank) && Objects.isNull(field.get(object))) {                    errorMessage.add("index[" + i + "]" + notBlank.message());                }                NotEmpty notEmpty = field.getAnnotation(NotEmpty.class);                if (Objects.nonNull(notEmpty) && Objects.isNull(field.get(object))) {                    errorMessage.add("index[" + i + "]" + notEmpty.message());                }            }        }        if (errorMessage.size() > 0) {            ResultResponse resultResponse = new ResultResponse().fail(HttpCodeEnum.FAIL.getCode(), errorMessage.stream().map(String::valueOf).collect(Collectors.joining(";")));            return resultResponse;        } else {            return new ResultResponse().success();        }    }
