添加依赖

在Maven的pom.xml文件中添加dubbo依赖

<span style="font-size:14px;"><dependency>
			<groupId>com.github.sgroschupf</groupId>
			<artifactId>zkclient</artifactId>
		</dependency>
		<dependency>
			<groupId>org.apache.zookeeper</groupId>
			<artifactId>zookeeper</artifactId>
		</dependency>
		<dependency>
			<groupId>com.alibaba</groupId>
			<artifactId>dubbo</artifactId>
			<exclusions>
				<exclusion>
					<artifactId>spring</artifactId>
					<groupId>org.springframework</groupId>
				</exclusion>
			</exclusions>
		</dependency></span>

服务提供者

DemoService.java

package com.alibaba.dubbo.demo;

public interface DemoService {
 
    String say(String name);
 
}

服务提供方实现接口：(对服务消费方隐藏实现)

package com.alibaba.dubbo.demo.provider;
 
import com.alibaba.dubbo.demo.DemoService;
@Service
public class DemoServiceImpl implements DemoService {
 
    public String say(String name) {
        return "Hello " + name;
    }
 
}

服务提供者xml配置文件

Dubbo采用全Spring配置方式，透明化接入应用，对应用没有任何API侵入，只需用Spring加载Dubbo的配置即可，Dubbo基于Spring的Schema扩展进行加载

<context:component-scan base-package="com.alibaba.dubbo.demo.provider" />

<dubbo:annotation package="com.bjhy.platform.statics.provider" />

 <dubbo:application name="platform-demo"  />

<dubbo:registry address="multicast://224.5.6.7:1234" />

<dubbo:registry protocol="zookeeper" address="192.168.0.2:1111" />

 <!-- 用dubbo协议在20880端口暴露服务 -->

import org.junit.runner.RunWith;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath*:META-INF/spring/module-*.xml")
public class Provider{

	public static void main(String[] args) throws Exception {
		ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath*:META-INF/spring/module-*.xml");
		context.start();
		System.out.println("服务已启动****");
		System.in.read();
	}
	
}
