Dubbo應用啓動與關閉流程日誌剖析——Annotation配置

原創 雲舒Lee 2019-01-14 12:57

基於 INFO 日誌，瞭解Dubbo應用的啓動與關閉流程，對使用有幫助，爲源碼剖析做準備。

示例項目源碼：spring-boot-rpc-dubbo-provider-annotation、spring-boot-rpc-dubbo-consumer-annotation

1. Service Provider

線程名稱描述(實例化方法)

main：應用主線程
Dubbo-Holder：Dubbo持有線程(DubboHolderListener.onApplicationEvent)
main-SendThread(127.0.0.1:2181)：ZooKeeper線程，服務傳出的請求隊列並生成心跳檢查(ClientCnxn.ClientCnxn() -> ClientCnxn.SendThread)
main-EventThread：ZooKeeper配置數據事件處理線程(ClientCnxn.ClientCnxn() -> ClientCnxn.EventThread)
DubboServerHandler-{ip:port}-thread-{num}：Dubbo服務端處理程序(NettyServer.NettyServer)
DubboShutdownHook：基於JVM關閉鉤子的Dubbo關閉線程(AbstractConfig.java:76)
Thread-{num}：基於JVM關閉鉤子的Spring應用上下文關閉線程(AbstractApplicationContext.registerShutdownHook)
New I/O worker #1：Netty工作線程

啓動步驟

0. 'Dubbo持有線程'開始運行
1. 應用上下文掃描Dubbo服務提供者的@Service註解組件定義
2. 暴露Dubbo服務提供者爲URL
3. 開始註冊Dubbo服務提供者URL到註冊中心(registry)
4. 啓動綁定到20880端口的Netty服務器
5. 加載本地註冊中心存儲文件數據
6. 建立與註冊中心的套接字連接會話
  1. 註冊Dubbo服務提供者URL
  2. 訂閱Dubbo服務提供者URL
  3. 通知訂閱Dubbo服務提供者URL的URL列表
8. Zookeeper客戶端收到新的配置事件

關閉步驟

0. 現在運行Dubbo關閉鉤子(DubboShutdownHook)
1. 關閉應用上下文
2. 關閉所有註冊中心
3. 銷燬某個註冊中心
  1. 銷燬註銷的Dubbo服務提供者URL
  2. 銷燬取消訂閱的Dubbo服務提供者URL
  3. ZooKeeper會話已關閉
  4. ZooKeeper事件處理線程關閉會話
4. 關閉Dubbo服務器
  1. 關閉綁定到20880端口的Netty服務器
  2. 所有客戶端套接字連接都已斷開，現在可以優雅地關閉(Dubbo服務器)
  3. 連接斷開來自某客戶端的某服務URL
  4. 註銷暴露的Dubbo服務
5. 應用上下文停止組件

線程名稱描述(實例化方法)

main：應用主線程
background-preinit：以後臺線程的方式觸發Spring Boot應用的早期初始化過程(BackgroundPreinitializer.onApplicationEvent)
Dubbo-Holder：Dubbo持有線程(DubboHolderListener.onApplicationEvent)
localhost-startStop-1：處理Tomcat容器的啓動和停止事件的線程(ContainerBase.initInternal)
main-SendThread(127.0.0.1:2181)：ZooKeeper線程，服務傳出的請求隊列並生成心跳檢查(ClientCnxn.ClientCnxn() -> ClientCnxn.SendThread)
main-EventThread：ZooKeeper配置數據事件處理線程(ClientCnxn.ClientCnxn() -> ClientCnxn.EventThread)

DubboSharedHandler-thread-1：共享的執行器服務(WrappedChannelHandler.SHARED_EXECUTOR)
DubboShutdownHook：基於JVM關閉鉤子的Dubbo關閉線程(AbstractConfig.java:76)
Thread-{num}：基於JVM關閉鉤子的Spring應用上下文關閉線程(AbstractApplicationContext.registerShutdownHook)

啓動步驟

0. 'Dubbo持有線程'開始運行
1. Web應用上下文掃描Dubbo服務消費者的@Reference註解組件定義
2. 加載本地註冊中心存儲文件數據
3. 建立與註冊中心的套接字連接會話
  1. 註冊Dubbo服務消費者URL
  2. 訂閱Dubbo服務消費者URL
  3. 通知訂閱Dubbo服務消費者URL的URL列表
4. 啓動Netty客戶端連接到Dubbo服務器
5. 從註冊中心URL引用Dubbo服務

關閉步驟

0. 現在運行Dubbo關閉鉤子(DubboShutdownHook)
1. 關閉所有註冊中心
2. 銷燬某個註冊中心
  1. 銷燬註銷的Dubbo服務消費者URL
  2. 銷燬取消訂閱的Dubbo服務消費者URL
  3. ZooKeeper會話已關閉
  4. ZooKeeper事件處理線程關閉會話
3. 關閉Web應用上下文
4. 在階段0中停止組件(默認的組件生命週期處理程序)
5. 關閉Netty通信通道
6. 關閉Dubbo連接
