JAVA+access综合测评系统毕业设计

一、系统概述

本系统采用Java Swing开发前端界面，结合Access数据库实现数据存储，专为教育机构打造的综合测评解决方案。系统包含学生管理、题库管理、在线测评、成绩分析四大核心模块，实现了测评流程的全自动化。

二、系统架构设计

1. 技术选型

前端：Java Swing
数据库：Access 2016
数据访问：UCanAccess JDBC驱动
开发工具：Eclipse + WindowBuilder

2. 系统架构

采用经典的MVC架构模式：

├── model（数据模型层）
│   ├── Student.java
│   ├── 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() {@Overridepublic 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));}
}

五、系统部署与测试

1. 环境要求

JDK 1.8+
Access 2016
UCanAccess 5.0.1

2. 部署步骤

创建Access数据库并导入表结构
配置DBController中的数据库路径
编译并运行LoginFrame类
使用默认管理员账号登录（admin/123456）

3. 测试用例

import org.junit.Test;
import static org.junit.Assert.*;public class ExamSystemTest {@Testpublic void testAddStudent() {StudentController controller = new StudentController();Student student = new Student("2025001", "张三", "男", "计算机1班");assertTrue(controller.addStudent(student));}@Testpublic void testCalculateScore() {ExamController controller = new ExamController();List<Question> questions = new ArrayList<>();questions.add(new Question(1, "Java的创始人是谁?", "A. Bill Gates", "B. James Gosling", "C. Steve Jobs", "B", 10));questions.add(new Question(2, "Java是哪一年诞生的?", "A. 1991", "B. 1995", "C. 1998", "B", 10));Map<Integer, String> answers = new HashMap<>();answers.put(1, "B");answers.put(2, "B");assertEquals(20, controller.calculateScore(answers, questions));}
}
