解决办法
在配置⽂件中，不要使⽤数据库加表的形式配置，直接给每个表配置
<!-- 这个是原来的配置-->
<!-- 配置需要指定⽣成的数据库和表，% 代表所有表 -->
<table catalog="interview"tableName="%">
<!-- mysql 配置 -->
<generatedKey column="id"sqlStatement="Mysql"identity="true"/>
</table>
<!-- 这个是现在的配置-->
<table tableName="department"domainObjectName="Department">
</table>
<table tableName="student"domainObjectName="Student">
</table>
虽然⼀个⼀个表设置是⿇烦了点，但是稳啊
这⾥再附带上我的所有配置吧，毕竟是成功了
