我目前正在嘗試使類具有serialize
方法。其目標是在其自己的功能中序列化Singleton
。有什麼方法可以在這個類中序列化一個類?類中的類的序列化
這裏是什麼,我嘗試了樣品:
public void serialize() {
Singleton commit = this.getInstance();
try {
FileOutputStream fileOut = new FileOutputStream(new Config().getDataFile());
ObjectOutputStream out = new ObjectOutputStream(fileOut);
out.writeObject(commit);
out.close();
fileOut.close();
} catch (Exception e) {
System.out.println("Unable to commit database changes.");
e.printStackTrace(System.out);
}
}
和下面的堆棧跟蹤:
Unable to commit database changes.
java.io.NotSerializableException: com.cuistot.data.Singleton
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1184)
at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:348)
at [...].Singleton.serialize(Singleton.java:50)
