After executing the new sql, the object id is changed

[Keafmd]

After executing the new sql, the object id is changed.
Why? Does this happen occasionally?

ptListMapper.insertPtList(ptList);
//It needs to be reset, otherwise the ID is incorrect
ptList.setId(ptListId);
return ptList;

mybatis.spring.boot.starter.version>1.3.2

Hello @Keafmd ,

It probably means that the value of id is auto-generated by the DB (i.e. AUTO_INCREMENT, IDENTITY, etc.) and MyBatis' useGeneratedKeys is enabled globally or for the statement.

https://mybatis.org/mybatis-3/configuration.html#settings

Note that MyBatis-Spring-Boot-Starter 1.3.2 is EOL (=no longer supported).
Please use a newer version.

As you said, I did make relevant configuration. Thank you!
