//注意mapper.xml不要用 AS 来定义表的别名字段的别名,where标签不要用大写，ew是mybatisplus写死的，不要修改！使用mybatis的@Select注解来写page有bug，例子：
// @Select(
// {
// "<script> SELECT ${ew.sqlSelect} FROM t_sys_user_medal tsum LEFT JOIN t_app_usermlq tau ON tsum.user_id = tau.id ${ew.customSqlSegment} </script>"
// }
// )分页使用Select注解有bug，数据不能封装到page里面，所以要写成xml格式
