我的java类突然变得不可序列化了

我的一个类突然开始抱怨它是不可序列化的。我已经改变了一些东西，但在其定义中看不到任何可能导致它的东西。我的java类突然变得不可序列化了

我得到该类的非序列化异常。

这些都是在课程开始时的所有定义，我看不到会导致问题的任何内容。

private static final long serialVersionUID = 1L; 
private ArrayList <Card> cards; 
private ArrayList <Card> selectedCards; 
private HashSet <Card> knownCards; 
private ArrayList <Card> aceHighs; 
private int numberOfKnownCards = 0; 
private int valueOfKnownCards = 0; 

public static final int sortHand = 1; 
public static final int sortSelectedCards = 2; 
protected int[] cardsPerSuit = {0,0,0,0}; 
private int numberOfDifferentSuits = 0; 
private int[] cardsPerRank = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0}; 
private int numberOfDifferentRanks = 0; 



private int whereToTakeFrom; 
private int whichDiscardToTake; 

private int cardCount = 0; 
private int selectedCount = 0; 
public int handValue = 0; 
private Deck deck;

这是两个比较我有可能是正在创建的问题：

private Comparator<Card> byRank = new Comparator<Card>() { 

public int compare(Card c1, Card c2) { 
    return c2.getCardRank()-c1.getCardRank(); 
} 
}; 

private Comparator<Card> bySuitAndRank = new Comparator<Card>() { 

public int compare(Card c1, Card c2) { 
    return (c1.getCardSuit()-c2.getCardSuit())*100 + c2.getCardRank()-c1.getCardRank(); 
} 
};

它有一个公共的，没有参数的构造函数吗？ – 2011-05-08 23:08:06

“卡”和“卡座”是否还有“可序列化”？ – BalusC 2011-05-08 23:09:24

你是否实现了序列化？如果是这样，你是否更改'serialVersionUID'的值？另外，1的UID不是一个很好的选择。 – debracey 2011-05-08 23:09:57

根据堆栈跟踪，类il.co.anykey.games.yaniv.lite.Hand$1（类Hand中的匿名类）不可序列化。

我确实有几个内部类，但他们认为它们是问题所以我将它们移出到外部文件。现在没有。 – theblitz 2011-05-09 00:23:21

但堆栈跟踪确实抱怨这个类。这不仅仅是一个内部课程，而是一个匿名课程。你检查过了吗？它是'new Foo（）{/ * ... methods/fields ... * /}'的任何一种。 – entonio 2011-05-09 00:31:35

这似乎是问题所在。我更改了代码，以便在使用它时创建比较器，而不是事先创建。完美的作品。非常感谢！ – theblitz 2011-05-09 00:44:24

尝试标志着有问题的transient领域。也许你可以在反序列化后重新构造它们。

我试着去遍历所有的领域，并一次标记几个瞬变。仍然没有帮助。 – theblitz 2011-05-08 23:20:54
