spring-boot-demo-dubbo

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

注意

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

  1. 下载镜像：docker pull wurstmeister/zookeeper

  2. 运行容器：docker run -d -p 2181:2181 -p 2888:2888 -p 2222:22 -p 3888:3888 --name zk wurstmeister/zookeeper

  3. 停止容器：docker stop zk

  4. 启动容器：docker start zk

运行步骤

  1. 进入服务提供方 spring-boot-demo-dubbo-provider 目录，运行 SpringBootDemoDubboProviderApplication.java
  2. 进入服务调用方 spring-boot-demo-dubbo-consumer 目录，运行 SpringBootDemoDubboConsumerApplication.java
  3. 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
