Springboot打包 依赖包到单独文件夹

在使用Springboot开发项目时，打包好的jar包是可以直接运行的，但是通常情况下，这个jar都会很大，因为它默认打包了所有的依赖jar包。此时，就可以通过maven-dependency-plugin插件将依赖包复制到独立的文件夹，在启动jar包的时候引用即可。

配置说明

1. cn.xuexiluxian.open.admin.OpenDeerApplication用于指定该jar包启动时的主类（建议加上）
2. 加上自己项目的groupId和artifactId即可
3. open-deer值自定义
4. ${project.build.directory}/libs依赖包输出目录
5. 其它写死
