java实验室预约管理系统（源码+数据库脚本）
代码说明：
随着高校教学资源逐步开发，高校教育资源的应用种类逐步增多。而实验室作为高校基本教育资源之一，与日常教学工作开展、课堂项目实践有着密切联系。由此，如何借助新时期技术，加强高校实验室应用数据信息程序开发，在高校智能化管理程序推广中占有基础性地位。该软件是以Java语言为实现预言。其功能在系统内部有源代码直接完成，操作人员只需输入一些简单的汉字，数字，即可达到自己的目标。 登陆账号：admin 密码：123456 package com.company; import com.company.Bean.Student;import com.company.Bean.Teacher;import com.company.Bean.User;import com.company.DB.DB; import javax.swing.*;import java.awt.event.ActionEvent;import java.awt.event.ActionListener; public class Main extends JFrame { private JPanel p; private JLabel lblName,lblPwd,lblRole; private JTextField txtName; private JPasswordField txtPwd; private JButton btnOk,btnCancle; String[] s = {"学生","教师","管理员"}; private JComboBox comboBox; public Main(){ super("用户登录界面"); p = new JPanel(); p.setLayout(null); lblRole=new JLabel("角色："); comboBox=new JComboBox(s); lblName = new JLabel("账户："); lblPwd = new JLabel("密码："); txtName = new JTextField(20); txtPwd = new JPasswordField(20); btnOk = new JButton("登录"); btnCancle = new JButton("取消"); //注册确定按钮的事件处理 btnOk.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { String strName = txtName.getText(); String strPwd = new String(txtPwd.getPassword()); System.out.println("用户名:" strName "密码:" strPwd); } }); //注册取消按钮的事件处理 btnCancle.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { //清空 txtName.setText(""); txtPwd.setText(""); } }); lblRole.setBounds(90,50,60,25); comboBox.setBounds(130,50,140,25); lblName.setBounds(90,80,60,25); txtName.setBounds(130,80,140,25); lblPwd.setBounds(90,110,60,25); txtPwd.setBounds(130,110,140,25); btnOk.setBounds(130,150,60,25); btnCancle.setBounds(200,150,60,25); p.add(lblRole); p.add(comboBox); p.add(lblName); p.add(txtName); p.add(lblPwd); p.add(txtPwd); p.add(btnOk); p.add(btnCancle); this.add(p); this.setSize(400,300); this.setLocation(300,300); //设置窗体不可改变大小 this.setResizable(false); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); btnOk.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { String account =txtName.getText().trim(); String password=txtPwd.getText().trim(); String role=null; if(comboBox.getSelectedItem().equals("管理员")){ role="admin"; } else if(comboBox.getSelectedItem().equals("学生")) { role="student"; } else{ role="teacher"; } if(role.equals("admin")){ User user=new User(account,password); if (DB.Login(user)) { JOptionPane.showMessageDialog(null, "登录成功", "", JOptionPane.PLAIN_MESSAGE); AdminMain adminMain = new AdminMain(); adminMain.setVisible(true); Main.this.setVisible(false); } else { JOptionPane.showMessageDialog(null,"账号密码错误", "", JOptionPane.PLAIN_MESSAGE); } } else if (role.equals("student")){ Student student=new Student(account,password); if(DB.studentLogin(student)){ StudentMain studentMain=new StudentMain(); studentMain.setVisible(true); Main.this.setVisible(false); JOptionPane.showMessageDialog(null, "登录成功", "", JOptionPane.PLAIN_MESSAGE); } else { JOptionPane.showMessageDialog(null,"账号密码错误", "", JOptionPane.PLAIN_MESSAGE); } } else if (role.equals("teacher")){ Teacher teacher=new Teacher(account,password); if(DB.teacherLogin(teacher)){ TeacherMain teacherMain=new TeacherMain(); teacherMain.setVisible(true); Main.this.setVisible(false); JOptionPane.showMessageDialog(null, "登录成功", "", JOptionPane.PLAIN_MESSAGE); } else { JOptionPane.showMessageDialog(null,"账号密码错误", "", JOptionPane.PLAIN_MESSAGE); } } } }); btnCancle.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { } }); } public static void main(String[] args) { // write your code here Main main=new Main(); main.setVisible(true); }}
