Jwebsocket Server啟動流程

JWebSocketFactory 工廠類根據 jwebsocket.xml設定檔初始化 Jwebsocket引擎，伺服器以及plugin chain.

 

 JWebSocketFactory: Starting jWebSocket Server sub system

  ....

 JWebSocketLoader: Loading jWebSocket.xml

AbstractJWebSocketInitializer: Instantiating engine...
2011-01-05 18:19:41,235 INFO  - AbstractJWebSocketInitializer: Engine tcp0 instantiated.
2011-01-05 18:19:41,236 DEBUG - JWebSocketFactory: Initializing servers...
2011-01-05 18:19:41,287 INFO  - AbstractJWebSocketInitializer: Custom servers instantiated.
2011-01-05 18:19:41,287 DEBUG - AbstractJWebSocketInitializer: server=[org.jwebsocket.server.CcicJwsServer@19b719d

 

...........

 

載入一系列plugins.....

 

這裡有一FlashBridgePlugIn值得注意，是用來做瀏覽器安全色用的，因為wesocket 是html5的一部分，很多瀏覽器不支援，所以用

flash來做橋，websocket協議的核心無非是在瀏覽器端實現socket介面，flash本身提供socket編程介面，所以這裡用flash做橋。。

連接埠為843。

2011-01-05 18:19:41,402 INFO  - JWebSocketFactory: jWebSocket server startup complete

。。。。。。。。。

 

 

當瀏覽器 用戶端串連時，握手過程。。。

 

TCPEngine: Received Header (GET / HTTP/1.1/nUpgrade: WebSocket/nConnection: Upgrade/nHost: 10.10.10.182:8787/nOrigin: http://10.10.10.122/nCookie: _login_username_cookie=233223432; _login_user_cookie_id=1292484678732_232323-295817044/n)

 

TCPEngine 介面用戶端請求，

 

TCPEngine: Parsed header (host: 10.10.10.182:8787, origin: http://10.10.10.122, location: ws://10.10.10.122:8787/, path: /, searchString: )

 

解析要求標頭，，，

TCPEngine: Sent handshake (HTTP/1.1 101 Web Socket Protocol Handshake/nUpgrade: WebSocket/nConnection: Upgrade/nWebSocket-Origin: http://10.10.10.122/nWebSocket-Location: ws://10.10.10.122:8787//n/n)

 

響應，握手。。

TCPEngine$EngineListener: Starting connector...  啟動connector 執行個體，

 TCPConnector: Starting TCP connector...

 jwebsocket 伺服器支援單線程+非同步IO及多線程兩種模式，對於多線程模式，這裡TCPEngine為一個線程，負責握手，一旦握手成功則啟動TCPConnector線程處理用戶端與伺服器之間的資料轉送。
