错误原因

在数据库连接时使用了 userSSL 参数，将sueSSL = true 改为 useSSL = false，项目可以正常跑起来了。

解决办法

修改前

 <property name="url" value="jdbc:mysql://localhost:3306/mybatis?useSSL=true&amp;useUnicode=true&amp;characterEncoding=UTF8"/>

修改后

 <property name="url" value="jdbc:mysql://localhost:3306/mybatis?useSSL=false&amp;useUnicode=true&amp;characterEncoding=UTF8"/>
