1首先下载zookeeper-3.4.6，修改zoo.cfg下的配置信息，然后启动zookeeper

2编写服务端

package com.mor.server.dubbo.service;

//方法接口
public interface DemoServer {

	String sayHello(String str);

}<pre name="code" class="java">/**
 * 
 */
package com.mor.server.dubbo.service;

import java.util.Date;

//方法实现
public class DemoServerImpl implements DemoServer {

	/**
	 * 返回添加后的语句
	 */
	public String sayHello(String str) {
		str = "Hello " + str + "  2:" + new Date();
		System.err.println("server:" + str);
		return str;
	}

}

/**
 * 
 */
package com.mor.main;

import java.io.IOException;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {

//先启动这个 注册到zookpeer里面
	public static void main(String[] args) throws IOException {
		ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "applicationProvider.xml" });
		context.start();
		System.out.println("按任意键退出");
		System.in.read();
	}

}

</beans>

启动服务端应用

编写客户端代码

package com.mor.client.dubbo.action;

import java.util.Date;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.mor.server.dubbo.service.DemoServer;



public class ChatAction {

    public void SayHello(){ 
	ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "applicationConsumer.xml" });
	context.start();
	DemoServer demoServer = (DemoServer) context.getBean("demoService");
	System.out.println("client:"+demoServer.sayHello("Wanggq"+"1:"+new Date())+"3:"+new Date());
    }

}

package com.mor.client.dubbo.main;

import com.mor.client.dubbo.action.ChatAction;

public class Main {

    public static void main(String[] args) throws InterruptedException {
    	int i=0;
    	while(i++<100){
    		ChatAction act = new ChatAction();
    		System.out.println("--------------------测试1111111------------------------------------");
    		act.SayHello();
    		Thread.sleep(3000);
    	}
    }

}

        ">

启动客户端，然后再控制台查看信息
