背景：
1.我们打包时其实需要很多资源打到jar包之外，这样子修改了配置后，就可以生效了。
2.包的命名: 以mj为例子：
业务层：
com.jn.mj // 这个是这个工程的总包名
com.jn.mj.gateway // web服集群
com.jn.mj.server // 游戏服
框架层:
com.jn.orm // 对orm的包装
com.jn.net // 对tcp和websocket的支持
com.jn.excel // 导表工具
1)目录结构
2)pom.xml

3)assembly.xml

</assembly>
4)package.sh // 打包时跳过测试，使用prod环境，这样子打的包不会有application.properties
mvn clean package -DskipTests=true -Pprod
5)start.sh // 注意：运行jar的路径！！！
#!/bin/bash# 这个路径特别重要，必须回到总目录下
cd `dirname $0`
cd ..java -jar ./lib/mj-0.0.1-SNAPSHOT.jar6)打包后，解压开
7)展开看下打包生成的东西
也就是我们的jar,配置和启动脚本都已经放到指定目录
8)双击bin/start.sh就可以运行起来了，而且会走config下application.properties配置的端口
