GUI实现猜数字游戏

猜数字游戏：选手输入姓名进行测试，输入猜的数字，判断是否有姓名，有的话系统判断是否猜对，猜对了文字提示，并出现保存按钮（数据库），提示猜的次数，同样猜小了，猜大了都有弹窗提示，选手可以查询排行榜，有时间限制，到时间弹窗提示，点击确定退出程序。
程序涉及的技术栈有Java基础知识，MVC三层架构，JDBC，MySQL数据库等等。

mapper层

userMapper接口

public interface UserMapper {
    //添加比赛用户信息
    int addUser(Connection connection, String username, int count);
    //查询所有用户信息
    List<User> getUsers(Connection connection);
}

userMapperImpl实现类

public class UserMapperImpl implements UserMapper {
    @Override
    public int addUser(Connection connection, String username, int count) {
        PreparedStatement pstm = null;
        int execute = 0;
        try {
            connection.setAutoCommit(false);
            String sql = "insert into user_two values (?,?,?)";
            Object[] params = {null, username, count};
            execute = JdbcUtil.execute(connection, pstm, sql, params);
            if (execute>0){
                connection.commit();
            }
        } catch (SQLException e) {
            e.printStackTrace();
            try {
                connection.rollback();
            } catch (SQLException e1) {
                e1.printStackTrace();
            }
        }finally {
            JdbcUtil.closeResource(connection,pstm);
        }
        return execute;
    }

    @Override
    public List<User> getUsers(Connection connection) {
        PreparedStatement pstm = null;
        ResultSet rs = null;
        ArrayList<User> userList = new ArrayList<>();
        User user;
        try {
            String sql = "select id,username,count from user_two order by count asc";
            Object[] params = {};
            rs = JdbcUtil.execute(connection, rs, pstm, sql, params);
            while (rs.next()){
                user = new User();
                user.setId(rs.getInt("id"));
                user.setUserName(rs.getString("username"));
                user.setCount(rs.getInt("count"));
                userList.add(user);
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return userList;
    }
}

service层

userService接口

public interface UserService {
    //添加比赛用户信息
    boolean addUser(String username, int count);
    //查询所有用户信息
    List<User> getUsers();
}

userServiceImpl实现类

public class UserServiceImpl implements UserService {
    private UserMapper userMapper;

    public UserServiceImpl() {
        this.userMapper = new UserMapperImpl();
    }

    @Override
    public boolean addUser(String username, int count) {
        boolean flag = false;
        Connection connection = JdbcUtil.getConnection();
        if (userMapper.addUser(connection, username, count) > 0) {
            flag = true;
        }
        JdbcUtil.closeResource(connection,null);
        return flag;
    }

    @Override
    public List<User> getUsers() {
        Connection connection = JdbcUtil.getConnection();
        List<User> userList = userMapper.getUsers(connection);
        return userList;
    }
}

controller层

public class UserController {
    UserServiceImpl userService = new UserServiceImpl();
    /**
     * 保存个人信息
     * @param username
     * @param count
     */
    public boolean operation(String username,int count){
        return userService.addUser(username, count);
    }

    /**
     * 查询排行榜
     */
    public List<User> getUser(){
        List<User> userList = userService.getUsers();
        return userList;
    }
}

pojo实体类

public class User implements Serializable {
    private static final long serialVersionUID = 1L;
    private Integer id;
    private String userName;
    private Integer count;

    public User(Integer id, String userName, Integer count) {
        this.id = id;
        this.userName = userName;
        this.count = count;
    }

    public User() {
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public Integer getCount() {
        return count;
    }

    public void setCount(Integer count) {
        this.count = count;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", userName='" + userName + '\'' +
                ", count=" + count +
                '}';
    }
}

JdbcUtil工具类

    private static String driver;
    private static String url;
    private static String username;
    private static String password;

    //加载配置文件
    static {
