深入解析中间件之-Dubbo

Alibaba Dubbo

QuickStart

在IDEA中运行Dubbo的快速入门：

  1. 不需要编译源码，不需要安装监控中心（dubbo-monitor）和管理中心（dubbo-admin）
  2. 安装并启动ZooKeeper，使用ZK作为Dubbo的注册中心
  3. 创建dubbo-demo项目，包含三个模块：api、prodvider、consumer
  4. 修改provider模块和consumer模块的注册方式使用ZooKeeper：zookeeper://127.0.0.1:2181
  5. IDEA中启动provider模块的Provider
  6. IDEA中启动consumer模块的Consumer

Provider启动后会一直运行，日志如下：

provider和consumer的注册中心配置都是ZooKeeper，查看ZooKeeper的节点信息。
可以看出DemoService的providers目前有dubbo://10.57.241.44:20880。

provider提供了服务：dubbo:service，consumer引用服务：dubbo:reference。
除此之外，provider在启动后，只要没有停止，就需要一直暴露dubbo协议：dubbo:protocol。

    <bean id="demoService" class="com.alibaba.dubbo.demo.provider.DemoServiceImpl"/>

为了模拟provider的负载均衡，我们再启动一个provider，并且更改协议端口为20881。再次查看ZK：
