maven构建dubbo服务的可执行jar包

dubbo提供者服务使用dubbo框架提供的Main方法类来运行：
dubbo框架提供：com.alibaba.dubbo.container.Main（可实现优雅关机ShutdownHook）

在提供者的pom.xml中配置以下maven插件：

注意在spring-application.xml中引入其他配置文件时要写为：

<import resource="classpath:spring/spring-mybatis.xml" />
    <import resource="classpath:spring/dubbo-provider.xml" />

因为spring-application.xml会被加载到${project.build.directory}/classes/META-INF/spring下，而不与引入的配置文件在同一目录下。

在对dubbo-provider服务打包成jar之前（maven install），需要将dubbo-provider服务依赖的工程先打包，在本地maven仓库生成相应的jar，这样dubbo-provider服务才会打包成功。最终在项目target目录下会生成lib文件夹和dubbo-provider.jar。lib文件夹存放的是dubbo-provider服务依赖的jar。
注：dubbo-provider.jar为什么能引用到lib文件夹内的jar，是因为dubbo-provider.jar的META-INF/MANIFEST.MF配置文件内说明了dubbo-provider服务依赖的jar。

运行dubbo-provider.jar：打开命令控制器，在dubbo-provider.jar所在的目录下输入java -jar dubbo-provider.jar & ，回车，出现下面的界面即运行成功：
