1.新增一個父項目赏表，并在父項目中添加依賴

    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>dubbo</artifactId>
        <version>2.5.8</version>
    </dependency>
    <dependency>
        <groupId>org.apache.zookeeper</groupId>
        <artifactId>zookeeper</artifactId>
        <version>3.4.6</version>
    </dependency>
    <dependency>
        <groupId>com.101tec</groupId>
        <artifactId>zkclient</artifactId>
        <version>0.7</version>
    </dependency>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
    </dependency>

2.在當前父項目中添加子模塊DubboInferface, 并新增一個IHelloInterface的接口

package com.qfedu.dubbo;

public interface IHelloInterface {

    String sayHello(String name);
}

3.在當前父項目中再添加子模塊DubboProvider

(1)在當前子模塊的pom文件中添加DubboInterface接口模塊的依賴

<dependency>
    <groupId>com.qfedu</groupId>
    <artifactId>DubboInterface</artifactId>
    <version>1.0-SNAPSHOT</version>
</dependency>

(2)新增接口子模塊中接口的實現(xiàn)類

package com.qfedu.dubbo;

public class HelloClass implements IHelloInterface {

    @Override
    public String sayHello(String name) {
        return "hello " + name;
    }
}

(3)在當前子模塊的resources下新增spring-dubbo的配置文件

<?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">

    <!--
        使用bean來創(chuàng)建一個HelloClass的實例對象
    -->
    <bean id="myDubbo" class="com.qfedu.dubbo.HelloClass" />

    <!--
        定義一個dubbo的應(yīng)用程序的名稱参滴，將來會在dubbo的管理中心查看
    -->
    <dubbo:application name="DubboProvider" />

    <!--
        配置dubbo協(xié)議，dubbo缆镣，hession搓茬， RMI
    -->
    <dubbo:protocol name="dubbo" port="20880" />

    <!--
        將當前應(yīng)用注冊到zookeeper注冊中心服務(wù)器之上
    -->
    <dubbo:registry address="zookeeper://ip:2181"></dubbo:registry>

    <!--
        將當前服務(wù)的接口暴露出去犹赖，以供消費方來消費
    -->
    <dubbo:service interface="com.qfedu.dubbo.IHelloInterface" ref="myDubbo" />
</beans>

(4)在當前子模塊中新增一個測試類將當前的spring-dubbo配置文件加載起來

package com.qfedu.dubbo;

import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestProvider {

    @Test
    public void testProvider(){
        //  加載spring-dubbo的配置文件
        new ClassPathXmlApplicationContext("classpath:spring-dubbo.xml");

        //  提示信息
        System.out.println("provider is ready");

        //  死循環(huán)保證"長連接"
        while (true){}
    }
}

4.新增子模塊DubboConsumer

(1)在當前子模塊中resources下新增spring-dubbo的配置文件

<?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">

    <!--
        配置當前應(yīng)用的名稱，給監(jiān)控中心來使用
    -->
    <dubbo:application name="DubboConsumer" />

    <!--
        設(shè)置注冊中心卷仑，從該注冊中心去消費服務(wù)
    -->
    <dubbo:registry address="zookeeper://ip:2181" />

    <!--
        獲取服務(wù)提供方所提供的接口數(shù)據(jù)
    -->
    <dubbo:reference interface="com.qfedu.dubbo.IHelloInterface" id="myDubbo" />
</beans>

(2)在當前子模塊中新增測試類加載spring-dubbo的配置信息峻村，并測試數(shù)據(jù)是否獲取

package com.qfedu.dubbo;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestConsumer {

    IHelloInterface hello;

    @Test
    public void testConsumer(){
        //  　加載spring-dubbo的配置文件
        ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:spring-dubbo.xml");

        //  通過id拿到spring-dubbo中定義的myDubbo節(jié)點對應(yīng)的對象
        hello = ac.getBean("myDubbo", IHelloInterface.class);

        //  調(diào)用mydubbo對象中的方法，完成測試
        String content = hello.sayHello("zhangsan");

        //  打印測試結(jié)果
        System.out.println(content);

        //while (true){}
    }
}

5.啟動zookeeper之后锡凝，運行provide測試類進行測試

log4j:WARN No appenders could be found for logger (org.springframework.core.env.StandardEnvironment).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
provider is ready

6.運行consumer的測試類

com.qfedu.dubbo.TestConsumer,testConsumer
log4j:WARN No appenders could be found for logger (org.springframework.core.env.StandardEnvironment).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
hello zhangsan

7.至此dubbo的簡單的配置完成
