Example 1
public ChannelPipeline getPipeline() throws Exception {
	ChannelPipeline pipeline = Channels.pipeline();
	//它负责把字节解码成Http请求。
	pipeline.addLast("decoder", new HttpRequestDecoder());
	//当Server处理完消息后,需要向Client发送响应。那么需要把响应编码成字节,再发送出去。故添加HttpResponseEncoder处理器。
	pipeline.addLast("encoder", new HttpResponseEncoder());
	//它负责把多个HttpMessage组装成一个完整的Http请求或者响应。到底是组装成请求还是响应,则取决于它所处理的内容是请求的内容,还是响应的内容。
	//这其实可以通过Inbound和Outbound来判断,对于Server端而言,在Inbound 端接收请求,在Outbound端返回响应。
	//如果Server向Client返回的数据指定的传输编码是 chunked。则,Server不需要知道发送给Client的数据总长度是多少,它是通过分块发送的,参考分块传输编码
	//pipeline.addLast("http-aggregator", new HttpObjectAggregator(65536));
	pipeline.addLast("deflater", new HttpContentCompressor());
	//该通道处理器主要是为了处理大文件传输的情形。大文件传输时,需要复杂的状态管理,而ChunkedWriteHandler实现这个功能。
	pipeline.addLast("http-chunked", new ChunkedWriteHandler());
	//自定义的通道处理器,其目的是实现文件服务器的业务逻辑。
	pipeline.addLast("handler", new FileServerHandler());
	return pipeline;
