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 。

项目结构

原型图

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

JdbcUtil工具类

public class JdbcUtil {private static String driver;private static String url;private static String username;private static String password;//加载配置文件static {Properties properties = new Properties();InputStream is = JdbcUtil.class.getClassLoader().getResourceAsStream(\"db.properties\");try {properties.load(is);} catch (IOException e) {e.printStackTrace();}driver = properties.getProperty(\"driver\");url = properties.getProperty(\"url\");username = properties.getProperty(\"username\");password = properties.getProperty(\"password\");}/*** 获取数据库连接对象* @return*/public static Connection getConnection(){Connection connection = null;try {Class.forName(driver);connection = DriverManager.getConnection(url, username, password);} catch (ClassNotFoundException e) {e.printStackTrace();} catch (SQLException e) {e.printStackTrace();}return connection;}/*** 查询公共类*/public static ResultSet execute(Connection connection, ResultSet resultSet, PreparedStatement preparedStatement,String sql,Object[] params) throws SQLException {preparedStatement = connection.prepareStatement(sql);for (int i = 0; i < params.length; i++) {preparedStatement.setObject(i+1,params[i]);}resultSet = preparedStatement.executeQuery();return resultSet;}/*** 增删改公共方法*/public static int execute(Connection connection, PreparedStatement preparedStatement,String sql,Object[] params) throws SQLException {preparedStatement = connection.prepareStatement(sql);for (int i = 0; i < params.length; i++) {preparedStatement.setObject(i+1,params[i]);}int updateRows = preparedStatement.executeUpdate();return updateRows;}/*** 释放资源*/public static boolean closeResource(Connection connection, ResultSet resultSet, PreparedStatement preparedStatement){boolean flag = true;if (connection!=null){try {connection.close();//GC回收connection=null;} catch (SQLException e) {e.printStackTrace();flag=false;}}if (resultSet!=null){try {resultSet.close();resultSet=null;} catch (SQLException e) {e.printStackTrace();flag=false;}}if (preparedStatement!=null){try {preparedStatement.close();preparedStatement=null;} catch (SQLException e) {e.printStackTrace();flag=false;}}return flag;}public static boolean closeResource(Connection connection, PreparedStatement preparedStatement){return closeResource(connection,null,preparedStatement);}}
