import org.jboss.netty.channel.socket.nio.NioClientSocketChannelFactory;

/**

public class TestNettyClient
{

	public static void main(String[] args)
	{
		//1.创建客户端启动器
		ClientBootstrap clientBootstrap = new ClientBootstrap(new NioClientSocketChannelFactory(Executors.newCachedThreadPool(), Executors.newCachedThreadPool()));
		//2.创建一个管道工厂，返回一个管道，并为该管道绑定处理器
		clientBootstrap.setPipelineFactory(new ChannelPipelineFactory()

			}
		});
		//绑定要连接的ip和端口
		clientBootstrap.connect(new InetSocketAddress("localhost", 8989));

	}
