mysql的STR_TO_DATE函数

STR_TO_DATE (#{user.fDjsj},'%H:%i')
使用这个函数来格式化日期，但是结果中含有秒，求解怎么将秒去掉

mysql> select now(),now()-interval second(now()) second;
+---------------------+-------------------------------------+
| now()               | now()-interval second(now()) second |
+---------------------+-------------------------------------+
| 2021-09-25 16:25:54 | 2021-09-25 16:25:00                 |
+---------------------+-------------------------------------+
