大白话剖析Dubbo架构图

1、启动provider

zookeeper.ZookeeperRegistry: [DUBBO]Register:

dubbo://192.168.1.102:20880/com.alibaba.dubbo.demo.DemoService?anyhost=true&application=demo-provider&dubbo=2.0.0&generic=false&interface=com.alibaba.dubbo.demo.DemoService&methods=sayHello&pid=20736&side=provider×tamp=1517824406227, dubbo version: 2.0.0, current host: 192.168.1.102

zookeeper.ZookeeperRegistry:DUBBO]Subscribe: provider://192.168.1.102:20880/com.alibaba.dubbo.demo.DemoService?anyhost=true&application=demo-provider&category=configurators&check=false&dubbo=2.0.0&generic=false&interface=com.alibaba.dubbo.demo.DemoService&methods=sayHello&pid=20736&side=provider×tamp=1517824406227, dubbo version: 2.0.0, current host: 192.168.1.102

日志分析：

（1）启动时向zookeeper注册中心注册dubbo://192.168.1.102:20880/com.alibaba.dubbo.demo.DemoService（目前我代码只有这一个接口，所以只会注册这一个）

（2）启动时向zookeeper注册中心订阅configurators（动态配置，category=configurators）

2、启动consumer

zookeeper.ZookeeperRegistry: [DUBBO]Subscribe:

consumer://192.168.1.102/com.alibaba.dubbo.demo.DemoService?application=demo-consumer&category=providers,configurators,routers&check=false&dubbo=2.0.0&interface=com.alibaba.dubbo.demo.DemoService&methods=sayHello&pid=34248&qos.port=33333&side=consumer×tamp=1517824680225, dubbo version: 2.0.0, current host: 192.168.1.102

日志分析：

（1）启动时向zookeeper注册中心订阅providers（接口）、configurators（动态配置）、routers（负载均衡）

3、注册中心向provider和consumer推送

4、建立长连接

consumer启动日志：

transport.AbstractClient:

[DUBBO] Successed connect to server /192.168.1.102:20880 from

NettyClient 192.168.1.102 using dubbo version 2.0.0, channel is

NettyChannel [channel=[id: 0x83137132, /192.168.1.102:2631 =>

/192.168.1.102:20880]], dubbo version: 2.0.0, current host:

192.168.1.102

日志分析：

启动consumer时，从netty客户端（zookeeper）成功的连接到了provider（192.168.1.102:20880 ）

5、定时发送统计数据给monitor
