spring boot的简配置方便的开发，下面通过本文给大家分享Spring boot整合Mybatis的方法，需要的朋友参考下
最近刚接触spring boot，正是因为他的及简配置方便开发，促使我下定决心要用它把之前写的项目重构，那么问题来了，spring boot怎么整合mybatis呢，下面几个配置类来搞定。
在我的代码当中是实现了数据库读写分离的，所以代码仅做参考，如有需要可以加我微信：benyzhous
【后续更新】
1、文件结构
DataBaseConfiguration.Java用来获取数据库连接配置信息，配置从application.properties中读取
MybatisConfiguration.java也就是MyBatis配置核心入口，构建连接创建SqlSessionFactory
2、下面直接贴代码，有问题的话可以留言或者加我的微信公众号：cha-baba，或者个人微信号：benyzhous
application.yml 相关配置
