首先新建父工程
新建spring boot项目
填写项目信息
指定该子项目的路径
如果是组件类型的子项目 可以删除application.xml和启动类
父工程pom文件
<?xml version="1.0" encoding="UTF-8"?>

<dependencyManagement>：指定子工程有相同jar包时，使用父工程的版本号，而子工程不用在额外指定
<dependencies>:为父子工程可以同时引入的jar包
子工程pom文件

注意com.vanpeng.assembly.BusinessApplication一定要配置 否则jar包启动会找不到主函数 pom也必须配置 这是在父子工程中必须配置的 意思是 需要以方式引入 而不是打成jar
