java - 在 Netty 中绑定(bind)到同一处理程序上不同端口的最佳方法是什么？

Question

请检查以下代码。在这里，我试图监听同一工厂的两个端口。目前只有一个端口在监听。请建议如何使用同一工厂实现多个端口监听，以实现所有端口的相同处理程序功能。

public static void main(String[] args)
{
    ChannelFactory factory = new NioServerSocketChannelFactory(Executors.newCachedThreadPool(),Executors.newFixedThreadPool(1));
    ServerBootstrap bootstrap = new ServerBootstrap(factory);
    ChannelPipelineFactory cpf = new ChannelPipelineFactory()
    {
        public ChannelPipeline getPipeline()
        {
            return Channels.pipeline(new testHandler());
        }
    };
    bootstrap.setPipelineFactory(cpf);
    bootstrap.setOption("child.tcpNoDelay", true);  
    ChannelGroup allChannels = new DefaultChannelGroup();
    Channel serverChannel = bootstrap.bind(new InetSocketAddress(5000));
    allChannels.add(serverChannel);
    Channel serverChannel1 = bootstrap.bind(new InetSocketAddress(6000));
    allChannels.add(serverChannel1);
    bootstrap.bind(new InetSocketAddress(5000));
}

您可以创建多个 ServerBootstrap 实例。每个ServerBootstrap使用一个Server Channel来绑定(bind)。
