Tcp网络编程 双向多次通讯

客户端

package tcptx;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;

public class TcpClient {

    public static void main(String[] args) throws UnknownHostException, IOException {
        //建立TCP的服务
        Socket s = new Socket(InetAddress.getLocalHost(), 9000);
        //获取Socket的输出流
         OutputStreamWriter sockOut = new OutputStreamWriter(s.getOutputStream());
         //获取键盘的输入流对象，读取数据
         BufferedReader keyReader = new BufferedReader(new InputStreamReader(System.in));
         String line = null;
         //不断读取键盘数据
         while((line = keyReader.readLine())!=null) {
             sockOut.write(line+"\r\n");//需要断行
             sockOut.flush();
             System.out.println("客户端数据已发出。。。");
         }
         //关闭资源
         s.close();
    }

}

服务端

package tcptx;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

public class TcpServer {

    public static void main(String[] args) throws IOException {
        //建立TCP的服务器，并监听一个端口
        ServerSocket serverSocket = new ServerSocket(9000);
        //接受客户端的连接
        Socket socket = serverSocket.accept();
        //获取输入流对象，读取客户端发送的内容
        BufferedReader socketReader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
        //读取客户端数据
        String line = null;
        while((line = socketReader.readLine())!=null) {
            System.out.println("数据接收中>>>>>>>>>>>");
            System.out.println(line);
        }
        //关闭资源
        serverSocket.close();
    }

}
