目录登陆界面的实现登陆界面代码Login类login的监听类 LoginListener聊天界面运行图Client类代码Server代码登陆界面代码

**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.*;

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)WlYAtpOJ;

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
