Dubbo学习（第一篇）之Demo案例搭建

其他 2018-05-08 05:19:15 阅读次数: 3

Dubbo是一款优秀的开源RPC框架，提到dubbo就不得不提到springcloud，博主之前刚刚粗略的看完了spingcloud微服务，这是一款很优秀的分布式架构全家桶。说起dubbo和springcloud的区别，只能说两者定位不同，前者定位是做一款稳定的RPC框架，而后者是一个微服务完整的生态体系，目前阿里也有意将dubbo向springcloud生态中靠近。

考虑到dubbo2017年重启维护并且准备把它作为阿里的重点开源项目。以及dubbo在国内的用户很活跃。so博主也开始着手研究dubbo这款优秀的框架并且持续更新，紧跟着阿里步伐，抱阿里大腿。

问：官网不是有demo吗？为什么你还来搭建这个demo？

答：由于官网的demo对于初学者并不清晰，最重要的是官网的demo是建立在main方法加载启动的，而对于我们来说希望的是消费者服务者部署在不同机器上面然后启动并且在zookeeper上面注册服务。

现在开始进行demo案例的搭建。

1.项目架构












common-parent:所有工程的目录，包括jar版本管理以及插件管理

dubbo-common:抽出一些项目的常用函数以及做jar包依赖管理

dubbo-demo:demo案例的父目录

----dubbo-demo-consumer:消费者

----dubbo-demo-face:公共接口

----dubbo-demo-provider:提供者

其中parent和common这两个模块目前主要为了jar包依赖，所以为了本篇文章的完整性，我会把这两个模块的依赖完整提供给大家，也算是一种福利吧。但是为了不影响我们的主题思想我把它放在后面的附录上面展示。

2.demo-face模块

本模块是服务提供者和服务消费者共同抽离出来的一个单独的服务接口模块。符合现在流行的复用思想


如上所示很简单只有一个demoService接口

public interface DemoService {

    String sayHello(String name);

}
本模块是后面要被消费者和提供者共同引用的

3.demo-provider

本模块是服务提供者，提供一个sayHello的服务


其中demoserviceImpl实现了接口DemoService

@Service("demoService")
public class DemoServiceImpl implements DemoService {
    public String sayHello(String name) {
        System.out.println("【dubbo provider】被远程消费者调用！");
        return "Hello,"+name;
    }
}
