│   ├── Question.java
│   ├── Exam.java
│   └── Score.java
├── view（视图层）
│   ├── LoginFrame.java
│   ├── MainFrame.java
│   ├── StudentManagerPanel.java
│   └── ExamPanel.java
└── controller（控制层）
    ├── DBController.java
    ├── StudentController.java
    ├── QuestionController.java
    └── ExamController.java

三、核心代码实现

1. 数据库连接模块

import net.ucanaccess.jdbc.UcanaccessDriver;
import java.sql.*;

public class DBController {
    private static final String DB_PATH = "jdbc:ucanaccess://D:/ExamSystem.accdb";
    private Connection conn;

    // 单例模式获取数据库连接
    public static DBController getInstance() {
        return DBControllerHolder.INSTANCE;
    }
    
    private static class DBControllerHolder {
        private static final DBController INSTANCE = new DBController();
    }
    
    private DBController() {
        try {
            Class.forName(UcanaccessDriver.class.getName());
            conn = DriverManager.getConnection(DB_PATH);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    
    // 执行查询
    public ResultSet executeQuery(String sql) throws SQLException {
        Statement stmt = conn.createStatement();
        return stmt.executeQuery(sql);
    }
    
    // 执行更新
    public int executeUpdate(String sql) throws SQLException {
        Statement stmt = conn.createStatement();
        return stmt.executeUpdate(sql);
    }
}

2. 学生管理模块

import java.sql.ResultSet;
import java.util.ArrayList;
import java.util.List;

public class StudentController {
    private DBController dbController = DBController.getInstance();
    
    // 添加学生
    public boolean addStudent(Student student) {
        String sql = String.format(
            "INSERT INTO Students(student_id, name, gender, class) " +
            "VALUES('%s', '%s', '%s', '%s')",
            student.getStudentId(),
            student.getName(),
            student.getGender(),
            student.getClass()
        );
        try {
            return dbController.executeUpdate(sql) > 0;
        } catch (SQLException e) {
            e.printStackTrace();
            return false;
        }
    }
    
    // 查询所有学生
    public List<Student> getAllStudents() {
        List<Student> students = new ArrayList<>();
        String sql = "SELECT * FROM Students";
        try (ResultSet rs = dbController.executeQuery(sql)) {
            while (rs.next()) {
                Student student = new Student(
                    rs.getString("student_id"),
                    rs.getString("name"),
                    rs.getString("gender"),
                    rs.getString("class")
                );
                students.add(student);
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return students;
    }
}

3. 在线测评模块

import java.util.*;

public class ExamController {
    private DBController dbController = DBController.getInstance();
    
    // 生成随机试卷
    public List<Question> generateExamPaper(int questionCount, int categoryId) {
        List<Question> allQuestions = loadQuestionsByCategory(categoryId);
        List<Question> examQuestions = new ArrayList<>();
        
        if (allQuestions.size() <= questionCount) {
            examQuestions.addAll(allQuestions);
        } else {
            Random random = new Random();
            Set<Integer> selected = new HashSet<>();
            while (selected.size() < questionCount) {
                int index = random.nextInt(allQuestions.size());
                if (!selected.contains(index)) {
                    selected.add(index);
                    examQuestions.add(allQuestions.get(index));
                }
            }
        }
        return examQuestions;
    }
    
    // 计算考试成绩
    public int calculateScore(Map<Integer, String> answers, List<Question> questions) {
        int score = 0;
        for (Map.Entry<Integer, String> entry : answers.entrySet()) {
            int questionId = entry.getKey();
            String userAnswer = entry.getValue();
            for (Question question : questions) {
                if (question.getId() == questionId && 
                    question.getAnswer().equalsIgnoreCase(userAnswer)) {
                    score += question.getScore();
                    break;
                }
            }
        }
        return score;
    }
}

4. 成绩分析模块

import java.sql.ResultSet;
import java.util.ArrayList;
import java.util.List;

public class ScoreAnalyzer {
    private DBController dbController = DBController.getInstance();
    
    // 获取班级平均分
    public double getClassAverageScore(String className) {
        String sql = String.format(
            "SELECT AVG(score) as avg_score FROM Scores " +
            "JOIN Students ON Scores.student_id = Students.student_id " +
            "WHERE Students.class = '%s'", className
        );
        try (ResultSet rs = dbController.executeQuery(sql)) {
            if (rs.next()) {
                return rs.getDouble("avg_score");
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return 0.0;
    }
    
    // 获取成绩分布
    public Map<String, Integer> getScoreDistribution(String className) {
        Map<String, Integer> distribution = new LinkedHashMap<>();
        distribution.put("0-59", 0);
        distribution.put("60-69", 0);
        distribution.put("70-79", 0);
        distribution.put("80-89", 0);
        distribution.put("90-100", 0);
        
        String sql = String.format(
            "SELECT score FROM Scores " +
            "JOIN Students ON Scores.student_id = Students.student_id " +
            "WHERE Students.class = '%s'", className
        );
        try (ResultSet rs = dbController.executeQuery(sql)) {
            while (rs.next()) {
                int score = rs.getInt("score");
                if (score < 60) distribution.put("0-59", distribution.get("0-59") + 1);
                else if (score < 70) distribution.put("60-69", distribution.get("60-69") + 1);
                else if (score < 80) distribution.put("70-79", distribution.get("70-79") + 1);
                else if (score < 90) distribution.put("80-89", distribution.get("80-89") + 1);
                else distribution.put("90-100", distribution.get("90-100") + 1);
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return distribution;
    }
}

四、系统界面设计

采用Java Swing开发的GUI界面示例：

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

public class LoginFrame extends JFrame {
    private JTextField txtUsername;
    private JPasswordField txtPassword;
    
    public LoginFrame() {
        setTitle("综合测评系统 - 登录");
        setSize(400, 300);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
        
        JPanel panel = new JPanel();
        panel.setLayout(null);
        add(panel);
        
        JLabel lblUsername = new JLabel("用户名:");
        lblUsername.setBounds(100, 80, 80, 25);
        panel.add(lblUsername);
        
        txtUsername = new JTextField();
        txtUsername.setBounds(190, 80, 120, 25);
        panel.add(txtUsername);
        
        JLabel lblPassword = new JLabel("密码:");
        lblPassword.setBounds(100, 120, 80, 25);
        panel.add(lblPassword);
        
        txtPassword = new JPasswordField();
        txtPassword.setBounds(190, 120, 120, 25);
        panel.add(txtPassword);
        
        JButton btnLogin = new JButton("登录");
        btnLogin.setBounds(150, 180, 100, 30);
        btnLogin.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                String username = txtUsername.getText();
                String password = new String(txtPassword.getPassword());
                if (authenticate(username, password)) {
                    dispose();
                    new MainFrame().setVisible(true);
                } else {
                    JOptionPane.showMessageDialog(
                        LoginFrame.this, 
                        "用户名或密码错误!", 
                        "登录失败", 
                        JOptionPane.ERROR_MESSAGE
                    );
                }
            }
        });
        panel.add(btnLogin);
    }
    
    private boolean authenticate(String username, String password) {
        // 实际项目中应查询数据库验证
        return "admin".equals(username) && "123456".equals(password);
    }
    
    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> new LoginFrame().setVisible(true));
    }
}
