配置： dubbo-server.xml

接口实现

public class SayHelloImpl implements ISayHello {
    public String sayHello(String msg) {
        return "Hello:" + msg;
    }
}

加载配置文件，启动server
public class Bootstrap {
    public static void main(String[] args) throws Exception {
        ClassPathXmlApplicationContext pathXmlApplicationContext =
                new ClassPathXmlApplicationContext("dubbo-server.xml");
        pathXmlApplicationContext.start();
        System.in.read();
    }
}

配置：dubbo-client.xml

启动客户端

public class DubboClient {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext pathXmlApplicationContext =
                new ClassPathXmlApplicationContext("dubbo-client.xml");
        //得到ISayHello 的远程代理对象
        ISayHello iSayHello = (ISayHello) pathXmlApplicationContext.getBean("iSayHello");
        System.out.println(iSayHello.sayHello("dubbo"));
    }
}
