简单的基于dubbo的调用

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();}}

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"xsi:schemaLocation="http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans.xsd        http://code.alibabatech.com/schema/dubbo        http://code.alibabatech.com/schema/dubbo/dubbo.xsd        "><dubbo:application name="hello-world-app" /><!-- 本机 伪集群 测试 --><dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" /><!-- dubbo暴露地址 --><dubbo:protocol name="dubbo" port="8088" /><!-- Dubbo要实现的接口类 --><dubbo:service interface="com.mor.server.dubbo.service.DemoServer"ref="demoService" /><!-- 和本地bean一样实现服务 --><bean id="demoService" class="com.mor.server.dubbo.service.DemoServerImpl" /></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);    }    }}

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"    xsi:schemaLocation="http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans.xsd        http://code.alibabatech.com/schema/dubbo        http://code.alibabatech.com/schema/dubbo/dubbo.xsd        ">     <!-- 消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 --><dubbo:application name="consumer-of-helloworld-app" />       <!-- 使用multicast广播注册中心暴露发现服务地址 --><dubbo:registry  protocol="zookeeper"  address="127.0.0.1:2181" />         <!-- 生成远程服务代理，可以和本地bean一样使用demoService --><!-- dubbo暴露地址 --><dubbo:protocol name="dubbo" port="8088" /><dubbo:reference id="demoService" interface="com.mor.server.dubbo.service.DemoServer" /></beans>

启动客户端，然后再控制台查看信息
