springboot2.X整合mybaits的坑

1.注意一个地方：mybaits扫描的包，是mapper，不是bean目录

不然报错：Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.ibatis.session.SqlSessionFactory]: Factory method 'sqlSessionFactory' threw exception; nested exception is org.apache.ibatis.type.TypeException: The alias 'Criterion' is already mapped to the value.............................

2.说明：别名包映射实体类包也行，但是不要使用

mybatis-generator生产的enableSelectByExample，enableDeleteByExample，selectByExampleQueryId。这些东西
