之前使用springMVC+spring+mybatis，總是被一些繁瑣的xml配置，有時候如果配置出錯，還要檢查各種xml配置，偶然接觸到了spring boot 后發現搭建一個web項目真的是1分鐘的事情，再也不用去管那么多xml配置，簡直神清氣爽，不用看那么多一坨xml，下面是我把以前的一些ssm項目改成了spring boot + mybatis，相對于來說優點太明顯了
1. 創建獨立的Spring應用程序
2. 嵌入的Tomcat，無需部署WAR文件
3. 簡化Maven配置
4. 自動配置Spring
5. 提供生產就緒型功能，如指標，健康檢查和外部配置
6. 絕對沒有代碼生成和對XML沒有要求配置
這個是百度百科上面對spring boot 優點的描述，其實我感覺也是這樣，大家可以試一下。
以下是具體的代碼實現（github地址：https://github.com/yihec/spring-boot-mybatis）
首先是pom文件的一些依賴

接著是application.yml數據庫配置

最后就是swagger的配置了,

最主要的代碼就是這些了，然后大功告成，后面的都是個人的業務邏輯了。
