以下是一个简单的学生信息管理系统的代码示例，使用了Java语言、MySQL数据库和IntelliJ IDEA开发工具。该系统包含了八个页面，包括登录页面、注册页面、主页面、添加学生页面、查询学生页面、修改学生页面、删除学生页面和退出页面。

首先，需要在MySQL数据库中创建一个名为"student_info"的数据库，并创建一个名为"students"的表，表结构如下：

CREATE TABLE students (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(50) NOT NULL,
    age INT NOT NULL,
    gender VARCHAR(10) NOT NULL
);

接下来，创建一个Java项目，并添加MySQL JDBC驱动库。

  1. 登录页面（LoginGUI.java）：
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class LoginGUI extends JFrame {
    private JTextField usernameField;
    private JPasswordField passwordField;
    private JButton loginButton;
    private JButton registerButton;

    public LoginGUI() {
        setTitle("登录");
        setSize(300, 200);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setLayout(new FlowLayout());

        JLabel usernameLabel = new JLabel("用户名:");
        usernameField = new JTextField(20);

        JLabel passwordLabel = new JLabel("密码:");
        passwordField = new JPasswordField(20);

        loginButton = new JButton("登录");
        registerButton = new JButton("注册");

        loginButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                String username = usernameField.getText();
                String password = new String(passwordField.getPassword());
                // TODO: 在数据库中验证用户名和密码
                // 如果验证成功，跳转到主页面
                // 否则，弹出错误提示框
            }
        });

        registerButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                // 跳转到注册页面
                dispose();
                new RegisterGUI().setVisible(true);
            }
        });

        add(usernameLabel);
        add(usernameField);
        add(passwordLabel);
        add(passwordField);
        add(loginButton);
        add(registerButton);
    }
}
  1. 注册页面（RegisterGUI.java）：
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class RegisterGUI extends JFrame {
    private JTextField usernameField;
    private JPasswordField passwordField;
    private JButton registerButton;

    public RegisterGUI() {
        setTitle("注册");
        setSize(300, 150);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setLayout(new FlowLayout());

        JLabel usernameLabel = new JLabel("用户名:");
        usernameField = new JTextField(20);

        JLabel passwordLabel = new JLabel("密码:");
        passwordField = new JPasswordField(20);

        registerButton = new JButton("注册");

        registerButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                String username = usernameField.getText();
                String password = new String(passwordField.getPassword());
                // TODO: 将用户名和密码保存到数据库
                // 注册成功后，跳转到登录页面
            }
        });

        add(usernameLabel);
        add(usernameField);
        add(passwordLabel);
        add(passwordField);
        add(registerButton);
    }
}
  1. 主页面（MainGUI.java）：
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class MainGUI extends JFrame {
    private JButton addButton;
    private JButton queryButton;
    private JButton editButton;
    private JButton deleteButton;
    private JButton logoutButton;

    public MainGUI() {
        setTitle("主页面");
        setSize(300, 200);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setLayout(new FlowLayout());

        addButton = new JButton("添加学生");
        queryButton = new JButton("查询学生");
        editButton = new JButton("修改学生");
        deleteButton = new JButton("删除学生");
        logoutButton = new JButton("退出");

        addButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                // 跳转到添加学生页面
                dispose();
                new AddStudentGUI().setVisible(true);
            }
        });

        queryButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                // 跳转到查询学生页面
                dispose();
                new QueryStudentGUI().setVisible(true);
            }
        });

        editButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                // 跳转到修改学生页面
                dispose();
                new EditStudentGUI().setVisible(true);
            }
        });

        deleteButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                // 跳转到删除学生页面
                dispose();
                new DeleteStudentGUI().setVisible(true);
            }
        });

        logoutButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                // 跳转到登录页面
                dispose();
                new LoginGUI().setVisible(true);
            }
        });

        add(addButton);

以上是一个简单的学生信息管理系统的代码示例，希望对你有帮助！请根据实际情况修改和完善代码

学生信息管理系统代码示例用idea和mysql数据库 八个页面以上
