我有这个异常,但我不明白为什么会抛出它,或者我应该如何处理它。
try {
os.writeObject(element);
} catch (IOException e) {
e.printStackTrace();
}
其中 element
是一个 TransformGroup
包含一些其他 TransformGroups
类 Atom 的实例:
public class Atom extends Group implements Serializable{
float pozX,pozY;
Group group= new Group();
Color3f blue = new Color3f(new Color(255));
Color3f black = new Color3f(new Color(0));
Sphere AtSph=new Sphere();
public Atom(final float WEIGHT, final int BOUNDS,final float radius,Color3f color)
{
AppSetting ap= new AppSetting(color, black);
AtSph=new Sphere(radius,1,100,ap);
}
}

AppSetting
(在 Atom 类中)只是一个扩展 Appearance 的自定义类。
最佳答案
你的对象的字段又具有它们的字段,其中一些没有实现Serializable
。在您的情况下,违规类是 TransformGroup
。如何解决?
- 如果这个类是你的,就让它
Serializable
- 如果该类是第 3 方,但序列化形式不需要它,则将该字段标记为
transient
- 如果您需要它的数据并且它是第三方的,请考虑使用其他序列化方式,例如 JSON、XML、BSON、MessagePack等,您可以在不修改其定义的情况下序列化第 3 方对象。
关于java - 为什么 writeObject 会抛出 java.io.NotSerializableException,我该如何解决?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/13895867/
