这篇文章给大家介绍使用Mybatis-Plus时的SqlSessionFactory问题及处理是怎样的，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。
前些日子工作中出现一个问题，项目中使用了MybatisPlus，然后出现了一个问题，Druid的其他的配置都可以正常使用，但是配置的SqlSessionFactory这个bean不能被加载，我在这个bean中加载的mybatis-config.xml文件也不能被加载，因为代码里使用了拦截器进行数据库的自动分页，找到问题后在这里mark一下。
其实这里不能加载的原因是因为MybatisPlus中自定义了MybatisSqlSessionFactoryBean这个类，而这个类是实现了接口FactoryBean<SqlSessionFactory>, InitializingBean, ApplicationListener<ApplicationEvent>，而在mybatis中有一个类也实现了这些接口，SqlSessionFactoryBean，所以在mybatisplus的配置文件中配置SqlSessionFactoryBean时需要换成mybatisplus中自定义的这个类MyBatisSqlSessionFactoryBean，并在类中加载对应的mybatis-config.xml文件。
