项目关键代码
util类
DbUtil:数据库连接
public class DbUtil {
static String url="jdbc:mysql://127.0.0.1:3306/demo?useUnicode=true&characterEncoding=UTF-8&useSSL=false";//数据库安装地址
static String username="root";//数据库用户名
static String password="123456";//数据库密码
static String driver="com.mysql.cj.jdbc.Driver";//连接的驱动
static { //注册驱动
try {
Class.forName(driver);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static Connection getConn() { //连接数据库
try {
return DriverManager.getConnection(url,username,password);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
}
Subtraction:卡牌计算
public class Subtraction {
static String two="2";
static BigDecimal num4=new BigDecimal(two);
public static String bloodSubtraction(String blood1,String cardNum,String cardDecor) { //血量计算
BigDecimal num1=new BigDecimal(blood1);
BigDecimal num2=new BigDecimal(cardNum);
if(cardDecor.equals("4")) {
BigDecimal num=num2.multiply(num4); //打出黑桃牌造成点数双倍的伤害
BigDecimal result =num1.subtract(num);
String s=result.toString();
return s;
}else {
BigDecimal result =num1.subtract(num2);
String s=result.toString();
return s;
}
}
public static String surplusSubtraction(String surplus,String num) { //剩余卡牌计算
BigDecimal num1=new BigDecimal(surplus);

}
public StringProperty getCardSurplus() {
return cardSurplus;
}
public void setCardSurplus(StringProperty cardSurplus) {
this.cardSurplus = cardSurplus;
}
}
dao类
UserDao:用户信息与数据库交互
public class UserDao {
public User findUser(String username,String password) { //查找用户
Connection connection=DbUtil.getConn();
String sql="select * from user_account where username=?";
User user =null;
PreparedStatement ps=null;
ResultSet rs =null;
try {
ps = connection.prepareStatement(sql);
ps.setString(1, username);
rs =ps.executeQuery();
while(rs.next()) {
user=new User();
user.setUsername(rs.getString("username"));
user.setPassword(rs.getString("password"));
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally {
try {
ps.close();
rs.close();
connection.close();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return user;
}
public boolean addUser(User user) { //添加用户
Connection conn =DbUtil.getConn();
String sql="insert into user_account(username,password) values(?,?)";
PreparedStatement ps=null;
int result=0;

ps.setString(2, user.getPassword());
result =ps.executeUpdate();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return result != -1;

controller类
GameController：游戏界面控制(展示部分关键代码)
public void changeUseMomentum(Momentum momentum) { //修改用牌时变量
atk.textProperty().bind(momentum.getAggressivity());
blood.textProperty().bind(momentum.getBlood());
surplus.textProperty().bind(momentum.getCardSurplus());

@SuppressWarnings("deprecation")

改进及感想
感想：虽然项目看起来不难，但一个人做的话各个知识点都需要学习，有些时间不足，尝试不同于swing的JavaFX界面设计时花费蛮多时间，但是上手后能实现不错的效果，游戏功能只是基本实现，和原本的规则比起来还差很多，后续游戏逻辑不难但唯独就是时间不够了，日后有待完善空间。经过这次课设让我对面向对象编程有了更深刻的理解，同时也学到了很多新知识，虽然只是浅尝辄止，但相信对我日后的学习会有帮助，同时有感叹计算机技术的高深，一项一项技术组合起来就能实现非常棒的项目，期待之后的学习中能加深理解，以后利用更多的知识实现更多的的功能，创造更好的项目。
改进：
- 卡牌的model或许可以写入数据库中，既方便读取也方便增改，以达到出牌补牌的操作
- JavaFX的动画功能和音乐功能还没有深刻学习，同时在这次项目中也没有运用，后续添加可以得到更好的体验
- 界面设计可以更加的合理和美观，功能可以更加的丰富和详细
- 游戏功能有待完全实现
