網上說是mybatis的jar包版本太高了，要把3.5的切回3.4
因個用的是mybatis-plus 3.2.0，裏面使用的是mybati 3.5.2的。
於是用mybatis-plus 3.0.5，使用的是mybati 3.4.6。
<!-- mybatis-plus begin -->
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.0.5</version>
</dependency>
<!-- mybatis-plus end -->
後來測試mybatis-plus 3.1.0 裏面使用的mybati 3.5.0 也同樣可以正常運行。
推薦使用mybatis-plus 3.1.0 因爲在3.0.7以後推出了許多新功能。
