Java 模拟 qq Java模拟qq软件的详细过程
冷丁_ 人气:0想了解Java模拟qq软件的详细过程的相关内容吗,冷丁_在本文为您仔细讲解Java 模拟 qq的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:Java,模拟,qq,Java,qq,界面模拟,下面大家一起来学习吧。
**之前在封装代码后出现了问题,按照最初的写法,在登陆完毕后弹出聊天界面后会卡死,原因是当时登陆界面和聊天界面都是使用的主线程,我的代码没有写其他线程,无法多线程运行,因此在弹出聊天界面时线程不够用了,就卡在了监听线程里,因为在监听线程中再有新的监听就会被卡住
在宇哥的指点下,将启动服务器和客户端的部分改为线程,就解决了此问题。改善后的代码简练和清晰了很多,更方便大家参考,代码如下:

登陆界面的实现
登陆界面主要使用了JFrame,以及相关的一些组件,并且在界面中加上监听
登陆界面效果图
登陆界面代码Login类
package com.lding.net; import javax.swing.*; import java.awt.*; /** * @program: Chat * @description: * @author: 王丁 * @date: 2021-09-26 08:58 **/ public class Login{ JTextField jTextField; public static void main(String[] args){ Login login = new Login (); login.showUI ("kk"); } public void showUI(String str){ JFrame jf = new JFrame (); jf.setTitle ("❤️DDqq登陆界面❤️"); jf.setSize (500, 400); jf.setDefaultCloseOperation (3); jf.setLocationRelativeTo (null); jf.setResizable (false); FlowLayout fl = new FlowLayout (FlowLayout.CENTER, 5, 5); jf.setLayout (fl); Dimension dim1 = new Dimension (500, 200);//图片大小 Dimension dim2 = new Dimension (100, 50);//标签大小 Dimension dim3 = new Dimension (300, 30);//输入框大小 Dimension dim4 = new Dimension (100, 40);//按钮大小 ImageIcon icon = new ImageIcon ("source/Login1.jpg"); JLabel labimg = new JLabel (icon); labimg.setPreferredSize (dim1); jf.add (labimg); JLabel labuser = new JLabel (); labuser.setText ("user:"); labuser.setPreferredSize (dim2); jf.add (labuser); JTextField textuser = new JTextField (); textuser.setPreferredSize (dim3); jf.add (textuser); JLabel labpassword = new JLabel (); labpassword.setText ("password:"); labpassword.setPreferredSize (dim2); jf.add (labpassword); JPasswordField textPassword = new JPasswordField (); textPassword.setPreferredSize (dim3); jf.add (textPassword); JButton button = new JButton (); button.setBorder (BorderFactory.createRaisedBevelBorder ()); button.setText ("login"); button.setPreferredSize (dim4); jf.add (button); jf.setVisible (true); LoginListener ll = new LoginListener(textuser,textPassword, jf); button.addActionListener (ll); this.jTextField=ll.jTextField; } }
login的监听类 LoginListener
package com.lding.net; import javax.swing.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; /** * @program: Chat * @description: * @author: 王丁 * @date: 2021-09-26 08:59 **/ public class LoginListener implements ActionListener { JTextField jTextField; JPasswordField jPasswordField; JFrame jf ; LoginListener( JTextField jTextField,JPasswordField jPasswordField,JFrame jf){ this.jf=jf; this.jTextField = jTextField; this.jPasswordField = jPasswordField; } @Override public void actionPerformed(ActionEvent e){ if(jTextField.getText().equals("Alice")&&String.valueOf(jPasswordField.getPassword()).equals("1234")){ System.out.println ("服务端登录!!"); String name =jTextField.getText(); new Server(name).start(); jf.dispose(); }else if(jTextField.getText().equals("Lding")&&String.valueOf(jPasswordField.getPassword()).equals("1234")){ String name =jTextField.getText(); System.out.println ("客户端登录!!"); new Client(name).start(); jf.dispose(); } } }
在登陆完毕后,需要跳转到聊天界面,这里采用的方法是通过一个flag标志来判断是否登陆完毕,当登陆完毕后,会创建新的聊天界面,并且登陆页面会被关闭
依然是双端通信,假定一端为客户端,一端为服务端,其实两端都可为用户。
聊天界面运行图
先登陆Alice的账号 密码为123456
登陆成功后显示ok,并等待连接
再登陆冷丁的账号,密码为123456
当lding账号登陆成功后完成连接,这时候会弹出两个新的JFram窗口,为聊天见面
随后可以发送消息,消息可以实时显示时间,并显示用户名
一方发送的消息会在另一方的窗口上实时显示出来
Client类代码
package com.lding.net; import com.lding.ui.MsgUI; import javax.swing.*; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import java.net.Socket; import java.text.SimpleDateFormat; import java.util.Date; /** * @program: Chat * @description: 客户端 * @author: 王丁 * @date: 2021-09-26 08:58 **/ public class Client extends Thread{ String name; public Client(String name) { this.name=name; } public static void main(String[] args) { String port="客户端"; Login login=new Login(); login.showUI(port); } @Override public void run(){ try { startClient(); } catch (IOException e) { e.printStackTrace (); } } void startClient() throws IOException{ Socket socket=new Socket("127.0.0.1",8888); //输入 输出流对象 InputStream inputStream=socket.getInputStream(); OutputStream outputStream=socket.getOutputStream(); MsgUI msgUI=new MsgUI(outputStream,name); JTextPane showmsgpane=msgUI.initUI("客户端"); outputStream.flush(); int count=1; while(true){ int msglenth=inputStream.read(); System.out.println("消息长度:"+msglenth); byte[] msgbytes=new byte[msglenth]; //将接下来的数据读入字节数组中 inputStream.read(msgbytes); count++; if(count%2==0){ SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//设置日期格式 String date = df.format(new Date());// new Date()为获取当前系统时间,也可使用当前时间戳 String getmsg=new String(msgbytes); String msg=showmsgpane.getText(); showmsgpane.setText(msg+date+" ["+getmsg+"]"+"说:"+"\n"); }else{ String getmsg=new String(msgbytes); String msg=showmsgpane.getText(); showmsgpane.setText(msg+getmsg+"\n"); } } } }
Server代码
package com.lding.net; import com.lding.ui.MsgUI; import javax.swing.*; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import java.net.ServerSocket; import java.net.Socket; import java.text.SimpleDateFormat; import java.util.Date; /** * @program: Chat * @description: * @author: 王丁 * @date: 2021-09-26 08:58 **/ public class Server extends Thread{ JTextField jTextField; String name; public Server(String name){ this.name=name; } public static void main(String[] args) { String port="服务端"; Login login=new Login(); login.showUI(port); } @Override public void run(){ try { startServer(); } catch (IOException e) { e.printStackTrace (); } } void startServer() throws IOException{ ServerSocket serverSocket=new ServerSocket(8888); System.out.println("等待连接!!"); Socket clientsocket=serverSocket.accept();//监听连接 System.out.println("连接成功!!"); InputStream inputStream=clientsocket.getInputStream(); OutputStream outputStream=clientsocket.getOutputStream(); MsgUI msgUI=new MsgUI(outputStream,name); JTextPane showmsgpane=msgUI.initUI("服务端"); //outputStream.flush(); int count=1; while(true){ int msglenth=inputStream.read(); System.out.println("消息长度是:"+msglenth); byte[] msgbytes=new byte[msglenth]; //将接下来的数据读入字节数组中 inputStream.read(msgbytes); count++; if(count%2==0){ SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//设置日期格式 String date = df.format(new Date());// new Date()为获取当前系统时间,也可使用当前时间戳 String getmsg=new String(msgbytes); String msg=showmsgpane.getText(); showmsgpane.setText(msg+date+" ["+getmsg+"]"+"说:"+"\n"); }else{ String getmsg=new String(msgbytes); String msg=showmsgpane.getText(); showmsgpane.setText(msg+getmsg+"\n"); } } } }
登陆界面代码
MsgUI
package com.lding.ui; import javax.swing.*; import java.awt.*; import java.io.OutputStream; /** * @program: Chat * @description: * @author: 王丁 * @date: 2021-09-26 08:59 **/ public class MsgUI extends JFrame { OutputStream outputStream; String name; public MsgUI(OutputStream outputStream,String name){ this.outputStream=outputStream; this.name=name; } public JTextPane initUI(String title){ setTitle(title); setSize(800,800); setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); setLocationRelativeTo(null); setLayout(new FlowLayout()); //接收显示框 JTextPane jtp=new JTextPane(); jtp.setPreferredSize(new Dimension(750,400)); JScrollPane jsp=new JScrollPane(jtp); jtp.getText(); Dimension dim=new Dimension(750,400);//按钮大小 //发送框 JTextPane jtp1=new JTextPane(); jtp1.setPreferredSize(new Dimension(750,200)); JScrollPane jsp1=new JScrollPane(jtp1); JButton btn=new JButton("发送"); add(jsp); add(jsp1); add(btn); setVisible(true); MsgListener msgl=new MsgListener(jtp1,this.outputStream,name); btn.addActionListener(msgl); return jtp; } }
MsgUIListener
package com.lding.ui; import javax.swing.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.IOException; import java.io.OutputStream; /** * @program: Chat * @description: * @author: 王丁 * @date: 2021-09-26 09:00 **/ public class MsgListener implements ActionListener { JTextPane jtp; OutputStream outputStream; String name; public MsgListener(JTextPane jtp,OutputStream outputStream,String name){ this.jtp=jtp; this.outputStream=outputStream; this.name=name; } @Override public void actionPerformed(ActionEvent e) { byte[] names=this.name.getBytes(); try { outputStream.write(names.length); outputStream.write(names); outputStream.flush(); } catch (IOException ex) { ex.printStackTrace(); } String msg=jtp.getText(); byte[] msgs=msg.getBytes(); try { outputStream.write(msgs.length); outputStream.write(msgs); outputStream.flush(); } catch (IOException ex) { ex.printStackTrace(); } jtp.setText(null); } }
之后会丰富更多功能 敬请期待! 感谢您的观看!!!
