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

</project>

3)assembly.xml

<assembly>
    <id>assembly</id>
    <formats>
        <format>tar.gz</format>
    </formats>

    <includeBaseDirectory>true</includeBaseDirectory>

    <fileSets>
        <fileSet>
            <directory>src/main/assembly/bin</directory>
            <outputDirectory>./bin</outputDirectory>
            <fileMode>0755</fileMode>
        </fileSet>

        <fileSet>
            <directory>src/main/resources</directory>
            <includes>
                <include>application.properties</include>
            </includes>
            <outputDirectory>./config</outputDirectory>
            <fileMode>0644</fileMode>
        </fileSet>
    </fileSets>

    <dependencySets>
        <dependencySet>
            <outputDirectory>lib</outputDirectory>
            <scope>runtime</scope>
        </dependencySet>
    </dependencySets>
</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.jar

6)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
