1.服务提供者
(1)工程目录
(2)接口代码 HelloService.java
package cn.ljh.dubbo.service; /**
* 功能概要：提供者service接口层
*
* @author ljh
* @since 2017年5月23日
*/
public interface HelloService {
public String sayHello(String name);
}
(3)接口实现 HelloServiceImpl.java
package cn.ljh.dubbo.service.impl; import cn.ljh.dubbo.service.HelloService; /**
* 功能概要：提供者service实现层
*
* @author ljh
* @since 2017年5月23日
*/
public class HelloServiceImpl implements HelloService{ public String sayHello(String name) {
// TODO Auto-generated method stub
return name + ", Hello World!";
} }
(4)配置文件 applicationProvider.xml

<!-- 具体的实现bean -->
<bean id="helloservice" class="cn.ljh.dubbo.service.impl.HelloServiceImpl" />
<!-- 提供方应用信息，用于计算依赖关系 -->

<!-- 使用zookeeper注册中心暴露服务地址 -->

<!-- 用dubbo协议在20880端口暴露服务 -->
<dubbo:protocol name="dubbo" port="20880" />
<!-- 声明需要暴露的服务接口 -->

(6)服务启动 HelloServiceTest.java
package cn.ljh.dubbo.service;
import java.io.IOException;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class HelloServiceTest {
public static void main(String[] args) {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
new String[]{"applicationProvider.xml"});
context.start();
System.out.println("服务注册成功");
try {
System.in.read();//让此程序一直跑，表示一直提供服务
} catch (IOException e) {
e.printStackTrace();
}
}
}

2.服务消费者
(1)工程目录
(2)接口代码(和服务提供者一致) HelloService.java
package cn.ljh.dubbo.service; /**
* 功能概要：提供者service接口层

* @author ljh
* @since 2017年5月23日
*/
public interface HelloService {
public String sayHello(String name);
}

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:reference id="helloService" interface="cn.ljh.dubbo.service.HelloService" /> </beans>
(4)log属性文件 log4j.properties
# Global logging configuration\uff0c\u5efa\u8bae\u5f00\u53d1\u73af\u5883\u4e2d\u8981\u7528debug

(5)服务消费 HelloServiceConsumerTest.java
package cn.ljh.dubbo.service;
import java.io.IOException;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class HelloServiceConsumerTest {
public static void main(String[] args) {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
new String[] { "applicationConsumer.xml" });
context.start();
HelloService providerService = (HelloService) context.getBean("helloService");
System.out.println(providerService.sayHello("Tom"));
try {
System.in.read();//让此程序一直跑
} catch (IOException e) {
e.printStackTrace();
}
}
}

3.测试
(1)启动服务提供者
启动HelloServiceTest的main方法
在监控中心可以看到服务已经注册http://192.168.137.130:8080/dubbo-admin/governance/services
(2)启动消费者
启动HelloServiceConsumerTest的main方法
在监控中心可以看到服务消费者http://192.168.137.130:8080/dubbo-admin/governance/applications
