**sb+zk+dubbo实现效果**

模拟了一个provider服务提供方和PC、Web两个服务消费方.gif

前言

先看一下上面的图有个简单的概念，然后开始编码。只需完成2件事情。
    1、Spring boot + zk + dubbo 框架搭建（1个主项目4个子模块）
    2、编写测试类，实现暴露服务的服务提供方、调用远程服务的服务消费方和服务注册与发现的注册中心 功能。

DemoServiceImpl 测试接口实现

Provider 测试执行main

package com.itunion.shop.service.impl; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Provider { public static void main(String[] args) throws Exception { System.setProperty("java.net.preferIPv4Stack", "true"); ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[]{ "shop-ds-rovider.xml"}); context.start(); System.out.println("服务提供方已经启动..."); System.in.read(); // press any key to exit } }

好了我们的sb+zk+dubbo 框架已经搭建好了，接下来我们执行一下看看结果！（zookeeper 服务记得启动哈）

启动shop-ds 暴露服务的服务提供方

服务提供方启动.jpg

启动shop-pc 服务消费方 -PC端启动

启动shop-web 服务消费方 -移动端启动

![fdb805817df7799498dbf887f86999dc.png][]

shop-web消费方调用.jpg

**最后预告**

如上面几张控制台截图我们模拟的 shop-ds(服务提供方)、shop-web(移动)和shop-pc(PC)消费方 都已经跑起来了，效果也达到我们预期的目的，那么还剩下最后一部分内容 我们会在 spring boot + zookeeper + dubbo 框架基础上 集成 mybatis + swagger 来实现增、删、改、查业务。
