• 新建源目錄（source）存放dubbo 生產者消費者配置檔案如圖：
• 
  -新建TestService.java

package com.test.dubbo.api;

public interface TestService {

    void sayhello(String name);

}

新建TestServiceImpl.java

package com.test.dubbo.api;

public class TestServiceImpl implements
 
 TestService{

    public void sayhello(String name) {

        System.out.println(name+"hello");

    }

}

生產者

package com.test.dubbo;

import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.context.support.GenericXmlApplicationContext;

import com.test.dubbo.api.TestService;

/**
 * CallbackConsumer
 *
 * @author william.liangf
 */
public class TestConsumer {

    public static void main(String[] args) throws Exception {
        String path = "classpath:consumer.xml";
        GenericXmlApplicationContext xml = new GenericXmlApplicationContext(path);

        xml.start();
        System.out.println("------------");
        TestService test = (TestService) xml.getBean("testService");

        for(int i=0;i<100;i++){
            test.sayhello(i+"");
        }
        System.in.read();
    }

}

• 啟動
  先執行TestProvider.java，如圖所示啟動註冊成功
  
  

執行TestConsumer.java消費註冊的服務出現圖示代表成功
