Netty是否可以将多个IO线程分配给同一通道?

问题描述

如果我要编码以下代码段:

If I were to code the following code segment:

class SimpleHandler extends SimpleChannelUpstreamHandler {
    ...
    public static void main( String[] args ) throws Exception {
    ServerBootstrap b = new ServerBootstrap( 
        new NioServerSocketChannelFactory( 
            Executors.newCachedThreadPool(), 
            Executors.newCachedThreadPool(), 
            10 ));
    b.setPipelineFactory( new ChannelPipelineFactory() {
        public ChannelPipeline getPipeline() throws Exception {
            return Channels.pipeline( new SimpleHandler() );
        }
    });
    b.bind( new InetSocketAddress( p ));
}

并假设以下情况:

• 通道C1已输入
• netty将线程T1分配给通道C1
• 线程T1从通道C1读取了所有输入后，尽管它仍在处理输入，但更多的输入到达了通道C1

我的问题是:netty是否将新线程分配给通道C1(假设线程池中有空闲线程)?

My question is: will netty assign a new thread to channel C1 (assuming there are free threads in the thread pool)?

预先感谢

推荐答案

一旦将线程/选择器分配给Channel，它将在其整个生命周期中使用相同的线程/选择器.因此，它将始终由同一时间提供服务.

Once a Thread / Selector is assigned to a Channel it will use the same during all of its life-time. So it will be served by the same all the time.
