记录SSM框架项目迁移SpringBoot框架-----pom.xml的迁移

第一步：迁移pom.xml文件（去除spring相关的依赖）

SSM中的pom：

1.去除Spring相关依赖（spring一些jar包springboot都是自带的）

2.测试类相关的如junit等

3.mybatis的

取剩下的dependency

去除完后SpringBoot的pom如下：

因为SpringBoot自带一些jar包版本，版本不一样会报黄色提示，只需要把version 版本号都去掉，就ok了。

这里记录迁移时出现的一个错误，就是springboot与之前共用了一个maven本地仓库，莫名其妙pom文件报了80个错误，貌似是jar包有问题，我这里又新建了一个springboot项目用的maven本地仓库。就没报错了。
