前面我们搞了发布Dubbo服务，发布的服务就是用来消费的，所以我们这里来调用服务，消费下；

创建maven项目 dubbo-demo-consumer

pom.xml配置下：

<dependencies>
	<dependency>
		<groupId>com.alibaba</groupId>
		<artifactId>dubbo</artifactId>
		<version>2.6.0</version>
	</dependency>
	<dependency>
		<groupId>com.101tec</groupId>
		<artifactId>zkclient</artifactId>
		<version>0.10</version>
	</dependency>
	<dependency>
		<groupId>org.apache.curator</groupId>
		<artifactId>curator-framework</artifactId>
		<version>4.0.1</version>
	</dependency>
	<dependency>
		<groupId>com.alibaba</groupId>
		<artifactId>fastjson</artifactId>
		<version>1.2.46</version>
	</dependency>
	<dependency>
		<groupId>log4j</groupId>
		<artifactId>log4j</artifactId>
		<version>1.2.17</version>
	</dependency>
	<dependency>
		<groupId>org.slf4j</groupId>
		<artifactId>slf4j-api</artifactId>
		<version>1.7.25</version>
	</dependency>
	<dependency>
		<groupId>org.apache.commons</groupId>
		<artifactId>commons-lang3</artifactId>
		<version>3.4</version>
	</dependency>
	<dependency>
		<groupId>io.netty</groupId>
		<artifactId>netty-all</artifactId>
		<version>4.0.35.Final</version>
	</dependency>
</dependencies>

再搞个dubbo-demo-consumer.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xmlns="http://www.springframework.org/schema/beans"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.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="demo-consumer"/>

    <!-- 使用zookeeper注册中心暴露服务地址 -->
    <dubbo:registry address="zookeeper://127.0.0.1:2181"/>

    <!-- 生成远程服务代理，可以和本地bean一样使用demoProviderService  check属性，启动的时候是否检查 一般设置为false 启动的时候不检查-->
    <dubbo:reference id="demoProviderService" check="false" interface="com.java1234.service.DemoProviderService"/>

</beans>

创建接口DemoProviderService.java

package com.java1234.service;

/**
 * 服务提供者接口
 * @author Administrator
 *
 */
public interface DemoProviderService {

	public String sayHello(String name);
}

搞个测试类ConsumerTest：

import java.io.IOException;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.java1234.service.DemoProviderService;

public class ConsumerTest {

	public static void main(String[] args) {
		ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"dubbo-demo-consumer.xml"});
		context.start();
		DemoProviderService demoProviderService=(DemoProviderService) context.getBean("demoProviderService");
		String result=demoProviderService.sayHello("你好");
		System.out.println("远程调用结果："+result);
		try {
			System.in.read();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		context.close();
	}
}

运行结果 远程调用结果：服务001

说明远程调用成功；
