java.io.WriteAbortedException：写入中止；问题

Question

在使用序列化保存我的游戏中获得的高分时遇到问题我在命令行中运行 jar 时得到的错误是 java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: sun.net.www.protocol.jar.JarURLConnection$JarURLInputStream 我认为这之前是有效的，不知道为什么现在有问题

可能是因为我有一个 InputStream，我也得到 java.io.NotSerializableException: java.io.BufferedInputStream

InputStream is_game_over = this.getClass().getResourceAsStream("/Snake/lib/font/game_over.ttf");
InputStream is_Premier = this.getClass().getResourceAsStream("/Snake/lib/font/Premier2019-rPv9.ttf");

GamePanel() {
    try {
        GamePanel g = rescueGame("/temp/SnakeGameInformation.ser");
        HIGH_SCORE = g.HIGH_SCORE;
    } catch(Exception e) {
        e.printStackTrace();
    }
        
    ...
}

public void gameOver(Graphics g) {
    ...

    //Updates the High Score
    if(applesEaten > HIGH_SCORE) {  
        HIGH_SCORE = applesEaten;
        highScoreDisplay(g, true);
    } else {
        highScoreDisplay(g, false);
    }

    //Save the game information before closing
    try {
        saveGame("/temp/SnakeGameInformation.ser");
    } catch(Exception e) {
        e.printStackTrace();
    }

     ...
}

public void saveGame(String file) throws IOException {
    ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream(file));
    out.writeObject(this);
    out.close();
}

public GamePanel rescueGame(String file) throws IOException, ClassNotFoundException {
    ObjectInputStream in = new ObjectInputStream(new FileInputStream(file));
    GamePanel g = (GamePanel)in.readObject();
    in.close();
    return g;
}

错误是我在声明

InputStream is_game_over = this.getClass().getResourceAsStream("/Snake/lib/font/game_over.ttf");
InputStream is_Premier = this.getClass().getResourceAsStream("/Snake/lib/font/Premier2019-rPv9.ttf");

在 class 上，所以它会被序列化，但它不能，所以我只是在构造函数中创建了变量，所以它不应该被序列化并解决了它！

代码应该是这样的

GamePanel() {
    try {
        InputStream is_game_over = this.getClass().getResourceAsStream("/Snake/lib/font/game_over.ttf");
        InputStream is_Premier = this.getClass().getResourceAsStream("/Snake/lib/font/Premier2019-rPv9.ttf");
        GamePanel g = rescueGame("/temp/SnakeGameInformation.ser");
        HIGH_SCORE = g.HIGH_SCORE;
    } catch(Exception e) {
        e.printStackTrace();
    }
        
    ...
}

public void gameOver(Graphics g) {
    ...

    //Updates the High Score
    if(applesEaten > HIGH_SCORE) {  
        HIGH_SCORE = applesEaten;
        highScoreDisplay(g, true);
    } else {
        highScoreDisplay(g, false);
    }

    //Save the game information before closing
    try {
        saveGame("/temp/SnakeGameInformation.ser");
    } catch(Exception e) {
        e.printStackTrace();
    }

     ...
}

public void saveGame(String file) throws IOException {
    ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream(file));
    out.writeObject(this);
    out.close();
}

public GamePanel rescueGame(String file) throws IOException, ClassNotFoundException {
    ObjectInputStream in = new ObjectInputStream(new FileInputStream(file));
    GamePanel g = (GamePanel)in.readObject();
    in.close();
    return g;
}
