dubbo源码阅读笔记--服务调用时序

上接dubbo源码阅读笔记--暴露服务时序，继续梳理服务调用时序，下图右面红线流程。

整理了调用时序图

分为3步，connect，decode，invoke。

连接

AllChannelHandler.connected(Channel) line: 38HeartbeatHandler.connected(Channel) line: 47MultiMessageHandler(AbstractChannelHandlerDelegate).connected(Channel) line: 28NettyServer(AbstractPeer).connected(Channel) line: 105NettyServer(AbstractServer).connected(Channel) line: 191NettyHandler.channelConnected(ChannelHandlerContext, ChannelStateEvent) line: 70

decode

DecodeableRpcInvocation.decode(Channel, InputStream) line: 92DecodeableRpcInvocation.decode() line: 74DubboCodec.decodeBody(Channel, InputStream, byte[]) line: 138DubboCodec(ExchangeCodec).decode(Channel, ChannelBuffer, int, byte[]) line: 134DubboCodec(ExchangeCodec).decode(Channel, ChannelBuffer) line: 95DubboCountCodec.decode(Channel, ChannelBuffer) line: 46NettyCodecAdapter$InternalDecoder.messageReceived(ChannelHandlerContext, MessageEvent) line: 134NettyCodecAdapter$InternalDecoder(SimpleChannelUpstreamHandler).handleUpstream(ChannelHandlerContext, ChannelEvent) line: 70

invoke

AllChannelHandler.received(Channel, Object) line: 54HeartbeatHandler.received(Channel, Object) line: 90MultiMessageHandler.received(Channel, Object) line: 28NettyServer(AbstractPeer).received(Channel, Object) line: 123NettyHandler.messageReceived(ChannelHandlerContext, MessageEvent) line: 91NettyHandler(SimpleChannelHandler).handleUpstream(ChannelHandlerContext, ChannelEvent) line: 88DefaultChannelPipeline.sendUpstream(DefaultChannelPipeline$DefaultChannelHandlerContext, ChannelEvent) line: 564DefaultChannelPipeline$DefaultChannelHandlerContext.sendUpstream(ChannelEvent) line: 791Channels.fireMessageReceived(ChannelHandlerContext, Object, SocketAddress) line: 296NettyCodecAdapter$InternalDecoder.messageReceived(ChannelHandlerContext, MessageEvent) line: 148NettyCodecAdapter$InternalDecoder(SimpleChannelUpstreamHandler).handleUpstream(ChannelHandlerContext, ChannelEvent) line: 70
