【 啟動服務的日誌分析 】

1.暴露本地服務

Export dubbo service com.alibaba.dubbo.demo.DemoService to local registry, dubbo version: 2.0.0, current host: 127.0.0.1

2.暴露遠程服務

Export dubbo service com.alibaba.dubbo.demo.DemoService to url dubbo://192.168.100.38:20880/com.alibaba.dubbo.demo.DemoService?anyhost=true&application=demo-provider&dubbo=2.0.0&generic=false&interface=com.alibaba.dubbo.demo.DemoService&loadbalance=roundrobin&methods=sayHello&owner=william&pid=8484&side=provider&timestamp=1473908495465, dubbo version: 2.0.0, current host: 127.0.0.1
 

Register dubbo service com.alibaba.dubbo.demo.DemoService url dubbo://192.168.100.38:20880/com.alibaba.dubbo.demo.DemoService?anyhost=true&application=demo-provider&dubbo=2.0.0&generic=false&interface=com.alibaba.dubbo.demo.DemoService&loadbalance=roundrobin&methods=sayHello&monitor=dubbo%3A%2F%2F192.168.48.117%3A2181%2Fcom.alibaba.dubbo.registry.RegistryService%3Fapplication%3Ddemo-provider%26backup%3D192.168.48.120%3A2181%2C192.168.48.123%3A2181%26dubbo%3D2.0.0%26owner%3Dwilliam%26pid%3D8484%26protocol%3Dregistry%26refer%3Ddubbo%253D2.0.0%2526interface%253Dcom.alibaba.dubbo.monitor.MonitorService%2526pid%253D8484%2526timestamp%253D1473908495729%26registry%3Dzookeeper%26timestamp%3D1473908495398&owner=william&pid=8484&side=provider&timestamp=1473908495465 to registry registry:

3.啟動Netty

Start NettyServer bind /0.0.0.0:20880, export /192.168.100.38:20880, dubbo version: 2.0.0, current host: 127.0.0.1

4.打開zk連接

INFO zookeeper.ClientCnxn: Opening socket connection to server /192.168.48.117:2181

5.將服務信息註冊到zk

Register: dubbo://192.168.100.38:20880/com.alibaba.dubbo.demo.DemoService?anyhost=true&application=demo-provider&dubbo=2.0.0&generic=false&interface=com.alibaba.dubbo.demo.DemoService&loadbalance=roundrobin&methods=sayHello&owner=william&pid=8484&side=provider&timestamp=1473908495465, dubbo version: 2.0.0, current host: 127.0.0.1

6.監聽zk

Subscribe: provider://192.168.100.38:20880/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&loadbalance=roundrobin&methods=sayHello&owner=william&pid=8484&side=provider&timestamp=1473908495465, dubbo version: 2.0.0, current host: 127.0.0.1

【 暴露本地服務和暴露遠程服務的區別 】

1.暴露本地服務

指暴露在用一個JVM裏面，不用通過調用zk進行遠程通信，例如：在同一個服務，自己調用自己的接口，沒必要進行網絡IP連接來通信。

2.暴露遠程服務

指暴露給遠程客戶端的IP和端口號，通過網絡來實現通信。
