記錄SSM框架項目遷移SpringBoot框架-----pom.xml的遷移

第一步：遷移pom.xml文件（去除spring相關的依賴）

SSM中的pom：

1.去除Spring相關依賴（spring一些jar包springboot都是自帶的）

2.測試類相關的如junit等

3.mybatis的

取剩下的dependency

去除完后SpringBoot的pom如下：

因為SpringBoot自帶一些jar包版本，版本不一樣會報黃色提示，只需要把version 版本號都去掉，就ok了。

這里記錄遷移時出現的一個錯誤，就是springboot與之前共用了一個maven本地倉庫，莫名其妙pom文件報了80個錯誤，貌似是jar包有問題，我這里又新建了一個springboot項目用的maven本地倉庫。就沒報錯了。
