第四步，分别在dubbo_api，produce，consumer的module子项目中创建java根目录和resources库

1. 例如：
   

第五步，在dubbo_api中创建一个接口，并在produce中实现

1. 接口

package com.qcby.service;

import org.springframework.stereotype.Service;

public interface HelloService {

    void saySomething(String msg);

}

2. 实现

package com.qcby.service.Impl;

import com.alibaba.dubbo.config.annotation.Service;
import com.qcby.service.HelloService;


public class HelloServiceImpl implements HelloService {
    @Override
    public void saySomething(String msg) {
        System.out.println(msg);
    }
}

第六步，分别在produce，consumer中创建一个类

1. produce中的类用于链接zookeeper

package com.qcby;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import java.io.IOException;

public class ProviderTest {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:springmvc.xml");
        context.start();
        System.out.println("Dubbo provider");
        try {
            System.in.read();   // 按任意键退出
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

2. consumer中的类用于调用实现的接口

package com.qcby;

import com.qcby.service.HelloService;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import java.io.IOException;

public class ConsumerTest {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "classpath:springmvc.xml" });

        context.start();
        HelloService demoService = (HelloService) context.getBean("helloService");

        demoService.saySomething("Hello World!");
        try {
            System.in.read();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

第七步，安装并开启zookeeper

1. 首先下载压缩包，并在任意文件夹中解压
   
2. 进入zookeeper-3.4.14文件夹中的conf并将文件名字为zoo_sample.cfg的复制一份，重命名为zoo.cfg
   
3. 返回上一层打开bin文件夹启动名字为zkServer.cmd的文件，看到如下结果即开启成功
   

第八步，先后运行第六步在produce，consumer中创建的类

在produce中输出如下结果即为成功
