基于springboot+mybatis的基础上再集成mybatis-plus相关问题

项目是基于springboot + mybatis，后面在集成mybatis-plus时遇到关键问题：

问题一：使用mybatis plus自带的mapper方法都报Invalid bound statement (not found)，而在mapper加入自定义的方法都可以正常调用

原因：这是因为先前使用mybatis时mybatisconfig中配置了SqlSessionFactory，而mybatis plus需要用到MybatisSqlSessionFactoryBean, 使用MybatisSqlSessionFactoryBean时，必须注释掉SqlSessionFactory， 否则默认只认SqlSessionFactory；而MybatisSqlSessionFactoryBean支持mybatis plus的同时还兼容SqlSessionFactory
