Java课程设计：基于swing的学生信息管理系统

本文主要是介绍Java课程设计：基于swing的学生信息管理系统，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、项目介绍

这款Java swing实现的学生信息管理系统和jsp版本的功能很相似，简单的实现了班级信息的增删改查，学生信息的增删改查，数据库采用的是mysql，jdk版本不限，是Java学习者学习参考非常好的一个小项目。

二、项目展示

登录

主界面

添加班级信息界面

班级信息管理界面

学生信息管理主界面

修改学生信息管理主界面

删除记录

三、源码展示

数据库工具类

public class DbUtil {private String dbUrl="jdbc:mysql://localhost:3306/db_student_swing?characterEncoding=utf8"; // 数据库连接地址private String dbUserName="root"; // 用户名,填写你自己的数据库用户名private String dbPassword=""; // 密码，你自己的用户名密码，这个就是我的，所以我不修改了private String jdbcName="com.mysql.jdbc.Driver"; // 驱动名称/*** 获取数据库连接* @return* @throws Exception*/public Connection getCon()throws Exception{Class.forName(jdbcName);Connection con=DriverManager.getConnection(dbUrl, dbUserName, dbPassword);return con;}/*** 关闭数据库连接* @param con* @throws Exception*/public void closeCon(Connection con)throws Exception{if(con!=null){con.close();}}public static void main(String[] args) {DbUtil dbUtil=new DbUtil();try {dbUtil.getCon();System.out.println("数据库连接成功！");} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();System.out.println("数据库连接失败");}}	
}

登录界面类

public class LogOnFrm extends JFrame {private JPanel contentPane;private JTextField userNameTxt;private JPasswordField passwordTxt;private DbUtil dbUtil=new DbUtil();private UserDao userDao=new UserDao();/*** Launch the application.*/public static void main(String[] args) {EventQueue.invokeLater(new Runnable() {public void run() {try {LogOnFrm frame = new LogOnFrm();frame.setVisible(true);} catch (Exception e) {e.printStackTrace();}}});}/*** Create the frame.*/public LogOnFrm() {//改变系统默认字体Font font = new Font("Dialog", Font.PLAIN, 12);java.util.Enumeration keys = UIManager.getDefaults().keys();while (keys.hasMoreElements()) {Object key = keys.nextElement();Object value = UIManager.get(key);if (value instanceof javax.swing.plaf.FontUIResource) {UIManager.put(key, font);}}setResizable(false);setTitle("学生信息管理系统");setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);setBounds(100, 100, 450, 343);contentPane = new JPanel();contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));setContentPane(contentPane);JLabel lblNewLabel = new JLabel("学生信息管理系统");lblNewLabel.setFont(new Font("宋体", Font.BOLD, 23));lblNewLabel.setIcon(new ImageIcon(LogOnFrm.class.getResource("/images/logo.png")));JLabel lblNewLabel_1 = new JLabel("\u7528\u6237\u540D\uFF1A");lblNewLabel_1.setIcon(new ImageIcon(LogOnFrm.class.getResource("/images/userName.png")));JLabel lblNewLabel_2 = new JLabel("\u5BC6  \u7801\uFF1A");lblNewLabel_2.setIcon(new ImageIcon(LogOnFrm.class.getResource("/images/password.png")));userNameTxt = new JTextField();userNameTxt.setColumns(10);passwordTxt = new JPasswordField();JButton btnNewButton = new JButton("\u767B\u5F55");btnNewButton.addActionListener(new ActionListener() {public void actionPerformed(ActionEvent e) {loginActionPerformed(e);}});btnNewButton.setIcon(new ImageIcon(LogOnFrm.class.getResource("/images/login.png")));JButton btnNewButton_1 = new JButton("\u91CD\u7F6E");btnNewButton_1.addActionListener(new ActionListener() {public void actionPerformed(ActionEvent e) {resetValueActionPerformed(e);}});btnNewButton_1.setIcon(new ImageIcon(LogOnFrm.class.getResource("/images/reset.png")));GroupLayout gl_contentPane = new GroupLayout(contentPane);gl_contentPane.setHorizontalGroup(gl_contentPane.createParallelGroup(Alignment.LEADING).addGroup(gl_contentPane.createSequentialGroup().addGroup(gl_contentPane.createParallelGroup(Alignment.LEADING).addGroup(gl_contentPane.createSequentialGroup().addGap(111).addComponent(lblNewLabel)).addGroup(gl_contentPane.createSequentialGroup().addGap(101).addGroup(gl_contentPane.createParallelGroup(Alignment.LEADING).addComponent(lblNewLabel_1).addComponent(lblNewLabel_2).addComponent(btnNewButton)).addGap(32).addGroup(gl_contentPane.createParallelGroup(Alignment.LEADING).addComponent(btnNewButton_1).addGroup(gl_contentPane.createParallelGroup(Alignment.LEADING, false).addComponent(passwordTxt).addComponent(userNameTxt, GroupLayout.DEFAULT_SIZE, 128, Short.MAX_VALUE))))).addContainerGap(111, Short.MAX_VALUE)));gl_contentPane.setVerticalGroup(gl_contentPane.createParallelGroup(Alignment.LEADING).addGroup(gl_contentPane.createSequentialGroup().addGap(30).addComponent(lblNewLabel).addGap(26).addGroup(gl_contentPane.createParallelGroup(Alignment.LEADING).addGroup(gl_contentPane.createSequentialGroup().addComponent(lblNewLabel_1).addGap(29).addGroup(gl_contentPane.createParallelGroup(Alignment.BASELINE).addComponent(lblNewLabel_2).addComponent(passwordTxt, GroupLayout.PREFERRED_SIZE, GroupLayout.DEFAULT_SIZE, GroupLayout.PREFERRED_SIZE))).addComponent(userNameTxt, GroupLayout.PREFERRED_SIZE, GroupLayout.DEFAULT_SIZE, GroupLayout.PREFERRED_SIZE)).addGap(36).addGroup(gl_contentPane.createParallelGroup(Alignment.BASELINE).addComponent(btnNewButton).addComponent(btnNewButton_1)).addContainerGap(60, Short.MAX_VALUE)));contentPane.setLayout(gl_contentPane);// 设置JFrame居中显示this.setLocationRelativeTo(null);}/*** 登录事件处理* @param e*/private void loginActionPerformed(ActionEvent evt) {String userName=this.userNameTxt.getText();String password=new String(this.passwordTxt.getPassword());if(StringUtil.isEmpty(userName)){JOptionPane.showMessageDialog(null, "用户名不能为空！");return;}if(StringUtil.isEmpty(password)){JOptionPane.showMessageDialog(null, "密码不能为空！");return;}User user=new User(userName,password);Connection con=null;try {con=dbUtil.getCon();User currentUser=userDao.login(con, user);if(currentUser!=null){dispose();new MainFrm().setVisible(true);}else{JOptionPane.showMessageDialog(null, "用户名或者密码错误！");}} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}finally{try {dbUtil.closeCon(con);} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}}}/*** 重置事件处理* @param e*/private void resetValueActionPerformed(ActionEvent evt) {this.userNameTxt.setText("");this.passwordTxt.setText("");}
