本文许多内容来源于http://dubbo.io/Developer+Guide-zh.htm#DeveloperGuide-zh-%E8%B0%83%E7%94%A8%E9%93%BE，感谢作者的分享。

dubbo的整体架构图中包括了很多内容，这里只分析服务暴露部份。

针对服务暴露，对上面的图做了些简化

时序图

分成6个阶段，下面分别列出每一个阶段的调用堆栈。

1 初始化接口invoker

JavassistProxyFactory.getInvoker(T, Class<T>, URL) line: 40 StubProxyFactoryWrapper.getInvoker(T, Class<T>, URL) line: 104 ProxyFactory$Adpative.getInvoker(Object, Class, URL) line: not available ServiceBean<T>(ServiceConfig<T>).exportLocal(URL) line: 516 ServiceBean<T>(ServiceConfig<T>).doExportUrlsFor1Protocol(ProtocolConfig, List<URL>) line: 469 ServiceBean<T>(ServiceConfig<T>).doExportUrls() line: 285 ServiceBean<T>(ServiceConfig<T>).doExport() line: 246 ServiceBean<T>(ServiceConfig<T>).export() line: 145

2 初始化exporter

DubboExporter<T>.<init>(Invoker<T>, String, Map<String,Exporter<?>>) line: 36 DubboProtocol.export(Invoker<T>) line: 240 ProtocolFilterWrapper.export(Invoker<T>) line: 55 ProtocolListenerWrapper.export(Invoker<T>) line: 56 Protocol$Adpative.export(Invoker) line: not available ServiceBean<T>(ServiceConfig<T>).doExportUrlsFor1Protocol(ProtocolConfig, List<URL>) line: 495 ServiceBean<T>(ServiceConfig<T>).doExportUrls() line: 285 ServiceBean<T>(ServiceConfig<T>).doExport() line: 246 ServiceBean<T>(ServiceConfig<T>).export() line: 145

3 初始化server

DubboProtocol.createServer(URL) line: 318 DubboProtocol.openServer(URL) line: 308 DubboProtocol.export(Invoker<T>) line: 258 ProtocolFilterWrapper.export(Invoker<T>) line: 55 ProtocolListenerWrapper.export(Invoker<T>) line: 56 Protocol$Adpative.export(Invoker) line: not available ServiceBean<T>(ServiceConfig<T>).doExportUrlsFor1Protocol(ProtocolConfig, List<URL>) line: 495 ServiceBean<T>(ServiceConfig<T>).doExportUrls() line: 285 ServiceBean<T>(ServiceConfig<T>).doExport() line: 246 ServiceBean<T>(ServiceConfig<T>).export() line: 145

4 绑定transporter

NettyTransporter.bind(URL, ChannelHandler) line: 33 Transporter$Adpative.bind(URL, ChannelHandler) line: not available Transporters.bind(URL, ChannelHandler...) line: 48 HeaderExchanger.bind(URL, ExchangeHandler) line: 41 Exchangers.bind(URL, ExchangeHandler) line: 63 DubboProtocol.createServer(URL) line: 329 DubboProtocol.openServer(URL) line: 308 DubboProtocol.export(Invoker<T>) line: 258 ProtocolListenerWrapper.export(Invoker<T>) line: 56 ProtocolFilterWrapper.export(Invoker<T>) line: 55 Protocol$Adpative.export(Invoker) line: not available ServiceBean<T>(ServiceConfig<T>).doExportUrlsFor1Protocol(ProtocolConfig, List<URL>) line: 495 ServiceBean<T>(ServiceConfig<T>).doExportUrls() line: 285 ServiceBean<T>(ServiceConfig<T>).doExport() line: 246 ServiceBean<T>(ServiceConfig<T>).export() line: 145

5 初始化codec

NettyServer(AbstractEndpoint).<init>(URL, ChannelHandler) line: 47 NettyServer(AbstractServer).<init>(URL, ChannelHandler) line: 59 NettyServer.<init>(URL, ChannelHandler) line: 63 NettyTransporter.bind(URL, ChannelHandler) line: 33 Transporter$Adpative.bind(URL, ChannelHandler) line: not available Transporters.bind(URL, ChannelHandler...) line: 48 HeaderExchanger.bind(URL, ExchangeHandler) line: 41 Exchangers.bind(URL, ExchangeHandler) line: 63 DubboProtocol.createServer(URL) line: 329 DubboProtocol.openServer(URL) line: 308 DubboProtocol.export(Invoker<T>) line: 258 ProtocolListenerWrapper.export(Invoker<T>) line: 56 ProtocolFilterWrapper.export(Invoker<T>) line: 55 Protocol$Adpative.export(Invoker) line: not available RegistryProtocol.doLocalExport(Invoker<T>) line: 153 RegistryProtocol.export(Invoker<T>) line: 107 ProtocolListenerWrapper.export(Invoker<T>) line: 54 ProtocolFilterWrapper.export(Invoker<T>) line: 53 Protocol$Adpative.export(Invoker) line: not available ServiceBean<T>(ServiceConfig<T>).doExportUrlsFor1Protocol(ProtocolConfig, List<URL>) line: 489 ServiceBean<T>(ServiceConfig<T>).doExportUrls() line: 285 ServiceBean<T>(ServiceConfig<T>).doExport() line: 246 ServiceBean<T>(ServiceConfig<T>).export() line: 145

6 初始化channelHandler

AllChannelHandler(WrappedChannelHandler).<init>(ChannelHandler, URL) line: 47 //-----------⑹ AllChannelHandler.<init>(ChannelHandler, URL) line: 32 AllDispatcher.dispatch(ChannelHandler, URL) line: 32 Dispatcher$Adpative.dispatch(ChannelHandler, URL) line: not available ChannelHandlers.wrapInternal(ChannelHandler, URL) line: 40 ChannelHandlers.wrap(ChannelHandler, URL) line: 33 NettyServer.<init>(URL, ChannelHandler) line: 63 //-----------------⑸ NettyTransporter.bind(URL, ChannelHandler) line: 33 //------------------⑷ Transporter$Adpative.bind(URL, ChannelHandler) line: not available Transporters.bind(URL, ChannelHandler...) line: 48 HeaderExchanger.bind(URL, ExchangeHandler) line: 41 Exchangers.bind(URL, ExchangeHandler) line: 63 DubboProtocol.createServer(URL) line: 329 //---------------------⑶ DubboProtocol.openServer(URL) line: 308 DubboProtocol.export(Invoker<T>) line: 258 ProtocolFilterWrapper.export(Invoker<T>) line: 55 ProtocolListenerWrapper.export(Invoker<T>) line: 56 Protocol$Adpative.export(Invoker) line: not available RegistryProtocol.doLocalExport(Invoker<T>) line: 153 RegistryProtocol.export(Invoker<T>) line: 107 ProtocolFilterWrapper.export(Invoker<T>) line: 53 ProtocolListenerWrapper.export(Invoker<T>) line: 54 //-----------------⑵ Protocol$Adpative.export(Invoker) line: not available ServiceBean<T>(ServiceConfig<T>).doExportUrlsFor1Protocol(ProtocolConfig, List<URL>) line: 489 //------------⑴ ServiceBean<T>(ServiceConfig<T>).doExportUrls() line: 285 ServiceBean<T>(ServiceConfig<T>).doExport() line: 246 ServiceBean<T>(ServiceConfig<T>).export() line: 145
