netty11---管道

客户端：

package com.server;
import java.net.Socket;
public class Client {
    public static void main(String[] args) throws Exception {
        Socket socket = new Socket("127.0.0.1", 10101);     
        socket.getOutputStream().write("hello".getBytes());     
        socket.close();
    }
}
