SpringBoot+zk+dubbo架构实践（四）：sb+zk+dubbo框架搭建（内附源码GitHub地址）

时间：2022-09-18 14:56:52

往期回顾

SpringBoot+zk+dubbo架构实践（一）：本地部署zookeeper
SpringBoot+zk+dubbo架构实践（二）：SpringBoot 集成 zookeeper
SpringBoot+zk+dubbo架构实践（三）：部署Dubbo-admin管理平台

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。

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

SpringBoot+zk+dubbo架构实践（四）：sb+zk+dubbo框架搭建（内附源码GitHub地址）
服务提供方启动.jpg

启动shop-pc 服务消费方 -PC端启动

SpringBoot+zk+dubbo架构实践（四）：sb+zk+dubbo框架搭建（内附源码GitHub地址）
shop-pc消费方调用.jpg

启动shop-web 服务消费方 -移动端启动

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。
