起因：看过Dubbo管控台的都知道，人家是个前后端分离的项目，可是一条打包命令能让两个项目整合在一起，我早想这样玩玩了。
1. 建立个maven父项目
next
这个作为父工程，next
Finish，然后把项目目录的src删除
2. 建立springboot子项目（Module）
next
next
这里引入模板引擎，是为了能运行前端项目，next
3. 建立前端子项目
这里就不是new Module了，而是直接在父项目根目录，用vue-cli3.0工具直接创建。
4. 先提前看一下最终项目目录（这个目录是我最后打包测试没问题的目录，所以会出现一些打包之后才会有的文件~）
5. 要实现打包整合只需要修改三个文件，即：三个pom.xml文件。
第一个，parent的pom.xml

6. 解释一下
最重要的插件就两个，一个是springboot项目里的maven-resources-plugin，另一个是vue项目里的frontend-maven-plugin。
资源插件的复制路径很好理解，vue-cli3.0打包的目录如图所示
而我们要在springboot项目里运行，就要把index.html文件复制到templates目录，其他文件复制到static目录。
7. 打包运行。
mvn clean package -Dmaven.test.skip=true
进入根目录，执行打包命令
..
进入server的target目录，执行java -jar命令
访问：
完成 https://github.com/Mysakura/boot-vue-parent
8. 引申 frontend-maven-plugin
这个插件不仅仅支持node+npm，还支持node+yarn。这里我也写了个例子 https://github.com/Mysakura/frontend-maven-plugin-demo
