使用

@Override
//使用注解标识，会进入AOP，把Vo对象中的@SysDictField属性标识指定的valueFieldName名称填充进去，通过反射（sql中typeId是要查询出来的，反射只填充name）
//我们有些表中有crrentUserId,一样可以通过自定义一个@UserField来实现UserName的填充
@EnableDimEnhance

    Page page = setPageParam(param, OrderItem.desc("id"));
    IPage iPage = counselorFollowRecordMapper.getCounselorFollowRecordPageList(page, param, labelSearchParam);
    return new Paging<>(iPage);
