1,首先 单个的 springboot 工程会建

可以一直下一步

需要四个工程(左右)

2,如图 这四个就是我建的springboot工程

 

　　将parent_house 工程中的 src 文件夹删除

　　domain_house  和 service_house 工程的 src   里面的 java文件夹和resource 文件夹 里面的东西删掉

　　web_house 里面可以不用动

3,配置文件

　　parent 配置文件

虽然都是springboot 工程  pom  文件中 配置父子关系,及依赖关系

还需要自己去调包结构

以及controller 里面的方法
