Dubbo服务的运行方式

1、使用Servlet容器（Tomcat、Jetty等）运行

缺点：增加复杂性（端口、管理） 浪费资源（内存）
2、自建main方法类来运行（Spring容器）

缺点： Dobbo本身提供的高级特性没用上 自已编写启动类可能会有缺陷
3、使用Dubbo框架提供的Main方法类来运行（Spring容器)

优点：框架本身提供（com.alibaba.dubbo.container.Main） 可实现优雅关机（ShutdownHook）
建议使用这种方式

        </plugin>
    </plugins>
</build>

4、定位到相应的目录下，执行命令启动服务

java -jar user-service.jar &

5、如果服务采用war包，直接部署在tomcat就ok了。

    <finalName>user-service</finalName>
    <resources>
        <resource>
            <targetPath>${project.build.directory}/classes</targetPath>
            <directory>src/main/resources</directory>
