repo地址：https://github.com/forlornMWS/spring-demo xyz/mwszksnmdys/springdemo/controller/TestController.testInsert()方法，或者SpringDemoApplicationTest中的test()方法

config用错类了，去mp里抄autoconfiguration

Comment From: yyhan

怎么解决的？

Comment From: forlornMWS

怎么解决的？

我之前写的Configuration类从其他mybatis的项目复制过来的，类用错了，配置sqlsessionfactory 的时候使用mybatisplus的类解决了
