initChannel

protected final void initChannel(io.netty.channel.Channel ch)
                          throws Exception

指定者:

initChannel 在类中 io.netty.channel.ChannelInitializer<io.netty.channel.Channel>

抛出:

Exception

webSocketHandComplete

protected abstract void webSocketHandComplete(io.netty.channel.ChannelHandlerContext ctx)

当握手成功后调用该抽象方法 注意此方法加入的handler需要手动触发 ctx.fireChannelActive() ctx.fireChannelRegistered()

 
         
		ChannelPipeline p=ctx.pipeline();
		p.addLast(new CodecHandler());//消息解码器
		p.addLast(new DefaultIdleListenerHandler<String>(new Listener()));//心跳适配器
		//为新加的handler手动触发必要事件
		ctx.fireChannelRegistered();
		ctx.fireChannelActive();	 			
}

参数:

ctx -

抛出:

Exception
