此 demo 主要演示了 Spring Boot 如何集成 Dubbo，demo 分了3个module，分别为公共模块
spring-boot-demo-dubbo-common、服务提供方spring-boot-demo-dubbo-provider、服务调用方spring-boot-demo-dubbo-consumer
本例注册中心使用的是 zookeeper，作者编写本demo时，采用docker方式运行 zookeeper
-
下载镜像：
docker pull wurstmeister/zookeeper -
运行容器：
docker run -d -p 2181:2181 -p 2888:2888 -p 2222:22 -p 3888:3888 --name zk wurstmeister/zookeeper -
停止容器：
docker stop zk -
启动容器：
docker start zk
- 进入服务提供方
spring-boot-demo-dubbo-provider目录，运行SpringBootDemoDubboProviderApplication.java - 进入服务调用方
spring-boot-demo-dubbo-consumer目录，运行SpringBootDemoDubboConsumerApplication.java - 打开浏览器输入 http://localhost:8080/demo/sayHello ，观察浏览器输出，以及服务提供方和服务调用方的控制台输出日志情况
