SpringMVC Controller List参数的校验工具方法

请求类：

@Data
public 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<ResultResponse> updateColumnInfos(
            @RequestBody List<ColumnUpdateDTO> 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<String> 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();
        }
    }
