【Java基础学习笔记】Java中Socket+Swing设计简单通信

1. 服务器端

package Tcp_IP;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;
import java.sql.Date;
import java.sql.Time;
import java.text.SimpleDateFormat;
import java.util.SimpleTimeZone;

import com.sun.org.apache.bcel.internal.generic.NEW;

import javafx.beans.binding.When;
import IO_Test.bufferread;

public class My_Server {
private BufferedReader reader;
private ServerSocket Ser_Sock;
private Socket socket;

void My_Server() {
// TODO Auto-generated constructor stub
try {
Ser_Sock = new ServerSocket(8766);
System.out.println("等待客户连接中···");
socket = Ser_Sock.accept();
reader = new BufferedReader
(new InputStreamReader(socket.getInputStream()));
while(reader!=null){
SimpleDateFormat forma =
new SimpleDateFormat("yyyy-mm-dd hh:mm:ss");
System.out.println("连接成功："+forma.format(new java.util.Date()));
System.out.println("获得客户端信息为："+reader.readLine());
}
reader.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void main(String[] args) {
// TODO Auto-generated method stub
My_Server SV = new My_Server();
SV.My_Server();
}

}

2. 客户端

package Tcp_IP;

import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.IOException;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.JTextField;
import javax.swing.border.BevelBorder;

public class My_Client extends JFrame{
Socket socket;
private JTextArea ta = new JTextArea();
private JTextField tf = new JTextField();
private PrintWriter writer;
Container c;

public My_Client(String titl) {
// TODO Auto-generated constructor stub
super(titl);
setDefaultCloseOperation(EXIT_ON_CLOSE);
c = getContentPane();
final JScrollPane  scollpane = new JScrollPane();
scollpane.setBorder(new BevelBorder(BevelBorder.RAISED));
getContentPane().add(scollpane, BorderLayout.CENTER);
scollpane.setViewportView(ta);
c.add(tf, "South");
ta.append("尝试连接\n");
try {
socket = new Socket("127.0.0.1", 8766);
} catch (UnknownHostException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
ta.append("已连接,请输入发送信息\n");
tf.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub

try {
writer = new PrintWriter(socket.getOutputStream(), true);
writer.println(tf.getText());

ta.append(tf.getText()+"\n");
ta.setSelectionEnd(tf.getText().length());
tf.setText("");}
catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

}
});
}
public static void main(String[] args) {
// TODO Auto-generated method stub
My_Client client = new My_Client("连接服务器");
client.setSize(200, 200);
client.setVisible(true);
}
}
