注： 带有图片的题目将题目图片放入根目录下创建的img文件夹放入(具体路径可自己指定)

  • 工具类（放在项目路径下的utils文件夹中）

MySpring.java

public class MySpring {private static HashMap<String,Object> beanBox = new HashMap<>();public static <T>T getBean(String className){T obj = null;try {obj = (T)beanBox.get(className);if(obj == null){Class clazz = Class.forName(className);obj = (T)clazz.newInstance();beanBox.put(className,obj);}} catch (Exception e) {e.printStackTrace();}return obj;}
}

QuestionFileReader.java

public class QuestionFileReader {private static HashSet<Question> questionBox = new HashSet<>();static {FileReader fr= null;BufferedReader bf= null;try {fr = new FileReader("src//dbfile//Question.txt");bf = new BufferedReader(fr);String question = bf.readLine();while (question!=null){String[] values = question.split("#");if(values.length==2){questionBox.add(new Question(values[0], values[1]));}else if(values.length==3){questionBox.add(new Question(values[0],values[1],values[2]));}question = bf.readLine();}} catch (Exception e) {e.printStackTrace();}finally {if (fr!=null){try {fr.close();} catch (IOException e) {e.printStackTrace();}}if (bf!=null){try {bf.close();} catch (IOException e) {e.printStackTrace();}}}}public HashSet<Question> getQuestionBox() {return questionBox;}
}

UserFileReader.java

public class UserFileReader {private static HashMap<String, User> userBox = new HashMap<>();public  static HashMap<String, User> getUserBox() {return userBox;}static {FileReader fileReader = null;BufferedReader bufferedReader = null;try {fileReader = new FileReader("src//dbfile//User.txt");bufferedReader= new BufferedReader(fileReader);String user = bufferedReader.readLine();while (user!=null){String[] value= user.split("-");userBox.put(value[0],new User(value[0],value[1]));user = bufferedReader.readLine();}} catch (Exception e) {e.printStackTrace();}finally {if(fileReader!=null){try {fileReader.close();} catch (Exception e) {e.printStackTrace();}}if (bufferedReader!=null){try {bufferedReader.close();} catch (IOException e) {e.printStackTrace();}}}}}
  • Dao数据持久层（放在项目路径下的dao文件夹中）

QuestionDao.java

public class QuestionDao {private QuestionFileReader fileReader = MySpring.getBean("util.QuestionFileReader");//HashSet 无get方法所以不能根据随机索引号获取题目；所以先使用ArrayList存储全部题目private  ArrayList<Question> questionPaper = new ArrayList(fileReader.getQuestionBox());public   ArrayList<Question> getPaper(int size){//由随机数获取的题目可能有重复的，用HashSet 去重复HashSet<Question> paper = new HashSet<>();while (paper.size()!=size) {Random r = new Random();int index = r.nextInt(this.questionPaper.size());paper.add(questionPaper.get(index));}//为了最后方便遍历最后再转用Arraylist 存储return new ArrayList<Question>(paper);}
}

UserDao.java

public class UserDao {public User selectOne(String acount){return UserFileReader.getUserBox().get(acount);}
}
  • Service业务逻辑层（放在项目路径下的service文件夹中）

UserService.java

public class UserService {private UserDao dao = MySpring.getBean("dao.UserDao");//登陆方法public String login(String account,String password){User user = dao.selectOne(account);while (user!=null){if(account.equals(user.getAccount())&&password.equals(user.getPassword())){return "登陆成功";}}return "账号或密码错误";}
}

QuestionService.java

public class QuestionService {private QuestionDao dao = MySpring.getBean("dao.QuestionDao");public ArrayList<Question> select(){return dao.getPaper(20);}
}
  • 数据映射类（放在项目路径下的domain文件夹中）

Question.java

//映射每一个问题
public class Question {private String title;private String answer;private String picture;public Question(){}public  Question(String title,String answer){this.title = title;this.answer = answer;}public Question(String title,String answer,String picture){this.title=title;this.answer=answer;this.picture=picture;}public void setTitle(String title) {this.title = title;}public void setAnswer(String answer) {this.answer = answer;}public void setPicture(String picture) { this.picture = picture; }public String getTitle() {return title;}public String getAnswer() {return answer;}public String getPicture() { return picture; }public boolean equals(Object obj) {if (this == (Question) obj) {return true;}if (obj instanceof Question) {if (this.title.substring(0,this.title.indexOf("
")).equals(((Question) obj).title.substring(0,this.title.indexOf("
")))) {return true;}}return  false;}public int hashCode() {return this.getTitle().hashCode();}
}

User.java

//映射每一个用户
public class User {private String account;private String password;public User(){}public User(String account, String password){this.account = account;this.password = password;}public String getAccount() {return account;}public String getPassword() {return password;}public void setAccount(String account) {this.account = account;}public void setPassword(String password) {this.password = password;}
}
  • 视图类（放在项目路径下的view文件夹中）

    BaseFrame.java

//模板模式
//设计一个规则 任何窗口想要画出来 执行流程固定
public abstract class BaseFrame extends JFrame {public BaseFrame(){}public BaseFrame(String title){super(title);}protected void init(){this.setFontAndSoOn();this.addElement();this.setFrameSelf();this.addListener();}//1,设置 字体颜色 背景 布局等protected abstract void setFontAndSoOn();//2,将属性添加1到窗体里protected abstract void addElement();//3,添加事件监听器protected abstract void addListener();//4,设置窗体自身protected abstract void setFrameSelf();
}

ExamFrame.java

public class ExamFrame extends BaseFrame {public ExamFrame(){this.init();}public ExamFrame(String title){super(title);this.init();}private QuestionService service = MySpring.getBean("service.QuestionService");private ArrayList<Question> paper = service.select();private int nowNum = 0;private int totalCount = paper.size();private int answerCount = 0;private int unanswerCount = totalCount;String[] realAnswer = new String[paper.size()];//初始化数组方法public void setArray(){for (int i=0;i<paper.size();i++){realAnswer[i] = "0";}}//创建一个线程对象 控制时间变化private
