dubbox -- 服务的启动与初始化

 

步骤	调用顺序	备注
容器启动	com.alibaba.dubbo.container.Main.main(args); dubbo.properties->dubbo.container->container.start() container->spring, log4j, jetty... SpringContainer.java->classpath*:META-INF/spring/*.xml->dubbo.xsd
bean初始化	等自定义标签->[dubbo-config-spring] DubboNamespaceHandler.java ->new DubboBeanDefinitionParser(ServiceBean.class,true) spring对bean的初始化操作 [dubbo-config-spring]ServiceBean.java->afterPropertiesSet()->setProvicer(), setApplication(), setModule(), setRegistries, etMonitor(), setProtocols, setPath() -> export()	自定义标签 的解析和 初始化
连接注册中心	ServiceBean.export()->ServiceConfig.java->doExportUrlsFor1Protocol()->暴露协议protocol.export() protocol=ExtensionLoader.getExtensionLoader(Protocol.class)..getAdaptiveExtension()--Protocol$Adaptive.java->ExtensionLoader.loadExtensionClasses()->loadFile()->META-INF/dubbo/internal, META-INF/dubbo/, META-INF/services/ ->filter, listener, mock->各类的export() protocol.export()调用链->RegistryProtocol.export()->getRegistry()->扩展的ZookeeperClient()-> registry.subscribe()加入监听列表	注册到注册中心， 并加入监听列表监听注册中心的消息通知
启动协议服务器	protocol.export()调用链->RestProtocol.export()->doExport()->server.start(), server.deploy	根据相就协议启动相应服务器

 

 

 

 

步骤	调用顺序	备注
容器启动	参考提供方
bean初始化	等自定义标签->[dubbo-config-spring] DubboNamespaceHandler.java ->new DubboBeanDefinitionParser(ReferenceBean.class,false)
连接注册中心	ReferenceBean.java->afterPropertiesSet()->ReferenceConfig.init()->createProxy()->refProtocol.refer() refProtocol=ExtensionLoader.getExtensionLoader(Protocol.class).getAdaptiveExtension() --Protocol$Adaptive.java ->ExtensionLoader.loadExtensionClasses()->loadFile()->META-INF/dubbo/internal/, META-INF/dubbo/, META-INF/services/ ->filter, listener, mock->各类的refer()
服务接口初始化	ReferenceConfig.init()->createProxy()->AbstractProxyFactory.getProxy()->JavasistProxyFactory.getProxy() service接口在实际运行时是com.alibaba.dubbo.common.bytecode.Proxy类的实例
