之前使用springMVC+spring+mybatis，总是被一些繁琐的xml配置，有时候如果配置出错，还要检查各种xml配置，偶然接触到了spring boot 后发现搭建一个web项目真的是1分钟的事情，再也不用去管那么多xml配置，简直神清气爽，不用看那么多一坨xml，下面是我把以前的一些ssm项目改成了spring boot + mybatis，相对于来说优点太明显了
1. 创建独立的Spring应用程序
2. 嵌入的Tomcat，无需部署WAR文件
3. 简化Maven配置
4. 自动配置Spring
5. 提供生产就绪型功能，如指标，健康检查和外部配置
6. 绝对没有代码生成和对XML没有要求配置
这个是百度百科上面对spring boot 优点的描述，其实我感觉也是这样，大家可以试一下。
以下是具体的代码实现（github地址：https://github.com/yihec/spring-boot-mybatis）
首先是pom文件的一些依赖

接着是application.yml数据库配置

最后就是swagger的配置了,

最主要的代码就是这些了，然后大功告成，后面的都是个人的业务逻辑了。
