java实现一个简答而实际的TCP 的服务端和客户端连接 服务端： package com.server; import java.io.DataOutputStream; import java.io.IOException; import java.io.OutputStream; import .ServerSocket; import .Socket; import .SocketTimeoutException; import java.text.SimpleDateFormat; import java.util.Date; public class TcpIpServer public static void main(String args) / info Auto-generated method stub ServerSocket serverSocket = null; try serverSocket = new ServerSocket(7777); System.out.println(getTime()+“服务端准备好啦.“ ); catch (IOException e) / info Auto-generated catch block e.printStackTrace(); while(true) try System.out.println(getTime()+“等待连接请求.“ ); / serverSocket.setSoTimeout(5*1000); Socket socket = serverSocket.accept(); System.out.println(getTime()+socket.getInetAddress()+“连接请求从这开始. “); OutputStream out = socket.getOutputStream(); DataOutputStream dos = new DataOutputStream(out); dos.writeUTF(“NoticeTest Message1 from Server.“); System.out.println(getTime()+“数据传送啦.“ ); dos.close(); socket.close(); /catch(SocketTimeoutException e) / System.out.println(“end!“); / System.exit(0); / catch (IOException e) / info Auto-generated catch block e.printStackTrace(); static String getTime() / info Auto-generated method stub SimpleDateFormat f = new SimpleDateFormat(“hh:mm:s“); return f.format(new Date(); 客户端： package com.client; import java.io.DataInputStream; import java.io.DataOutputStream; import java.io.IOException; import java.io.InputStream; import .Socket; import .UnknownHostException; public class TcpIpClient public static void main(String args) / info Auto-generated method stub String serverIp = ““; System.out.println(“服务端连接中.服务端 IP : “ + serverIp); try Socket socket = new Socket(serverIp, 7777); InputStream in = socket.getInputStream(); DataInputStream dis = new DataInputStream(in); System.out.println(“从服务端获得消息: “ + dis.readUTF(); System.out.println(“连接终止.“ ); dis.close(); socket.close(); System.out.println(“关闭连接.“ ); catch (UnknownHostException e) / info Auto-generated catc
