Java模拟qq软件的详细过程

2022-01-21 11:46冷丁_ Java教程

这篇文章主要为大家详细介绍了用Java实现模拟QQ,实现了消息通信+登陆界面美化,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

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。后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

登陆界面代码Login类

package com.lding.net;

import javax.swing.*;
import java.awt.*;

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
