java.io.NotSerializableException

java.io.NotSerializableException

我有这个异常，我不明白为什么会抛出该异常，或者应该如何处理。

try {    os.writeObject(element);} catch (IOException e) {    e.printStackTrace();}

哪里element是一个TransformGroup包含一些其他TransformGroups类的Atom的一个实例：

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);    }}

注意：AppSetting（在Atom类中）只是扩展Appearance的自定义类。

对象的字段又包含其字段，其中某些字段未实现Serializable。就你而言，令人反感的课程是TransformGroup。怎么解决呢？

  • 如果班级是你的，那就上 Serializable
  • 如果班级是第三方，但你不需要序列化形式，请将字段标记为 transient
  • 如果你需要其数据并且是第三方，请考虑其他序列化方式，例如JSON，XML，BSON，MessagePack等，你可以在不修改其定义的情况下序列化第3方对象。

@EscBed @EJB中的托管bean会导致java.io.NotSerializableException

@EscBed @EJB中的托管bean会导致java.io.NotSerializableException

我一直在用@ViewScoped托管bean敲打我的头.我正在使用表单的“schedule”组件来显示一些事件.当用户点击某个特定的按钮时,viewscoped bean中的一个方法是使用ajax调用的,但是每次我得到一个
“ java.io.NotSerializableException”,如果我更改managed-bean范围以请求解决问题.

我究竟做错了什么？有任何想法吗？

这是我的托管bean：

@ManagedBean(name = "schedule")
@ViewScoped
public class ScheduleMBean implements Serializable {

    @EJB
    private CongeBean congeBean;


    @ManagedProperty(value = "#{sessionBean}")
    private SessionMBean sessionBean;

    private DefaultScheduleModel visualiseurConges = null;

    public ScheduleMBean(){

    }
    @postconstruct
    public void init() {

        if(visualiseurConges == null){

                visualiseurConges = new DefaultScheduleModel();
        }



    }

    public void updateSchedule(){

        visualiseurConges.addEvent(new DefaultScheduleEvent("test",new Date(),new Date() ));



    }

    public void setVisualiseurConges(DefaultScheduleModel visualiseurConges) {
        this.visualiseurConges = visualiseurConges;
    }

    public DefaultScheduleModel getVisualiseurConges() {



        return visualiseurConges;
    }

    public void setSessionBean(SessionMBean sessionBean) {
        this.sessionBean = sessionBean;
    }

    public SessionMBean getSessionBean() {
        return sessionBean;
    }



}

解决方法

@ViewScoped bean存储在HTTP会话中.存储在HTTP会话中的任何对象都需要实现 Serializable.另请参见 JSF managed bean causing java.io.NotSerializableException during Tomcat deployment和 java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException.

NotSerializableException通常是自解释的,因为它提到了需要序列化的类的完整限定名,但不能因为它不实现Serializable.

然而,在这种特殊情况下,这个名称似乎表示一个自动生成的类,很可能由EJB容器自动生成,因此完全脱离了你的控制.

我以前从来没有看到这个问题,Google似乎也没有太多关于这个问题.基于stacktrace,你使用的是Glassfish v3,所以我建议发布一个issue.同时您最好的选择是将JSF视图状态设置为服务器端.

更新：MyFaces中的类似问题表明在反序列化期间使用错误的类加载器的JSF impl具体问题.升级JSF impl应该可以解决问题：@EJB in @ViewScoped @ManagedBean causes java.io.NotSerializableException.

我一直在用@ViewScoped Managed-Bean来敲打我的头。我正在使用primeface的“计划”组件以显示一些事件。当用户单击特定按钮时，使用ajax在viewscoped bean中调用一个方法，但是每次我得到一个“ java.io.NotSerializableException”时，如果我更改托管bean范围以请求该问题，就会消失。

我究竟做错了什么？有任何想法吗？

这是我的托管bean：

android-编写Parcelable对象获取java.io.NotSerializableException

我有一个名为Shop的类,它具有2个字段和1个静态字段.该类实现Parcelable接口：

public class Shop implements Parcelable{
   private static int SHOP_ID = 12;

   private String name;
   private long fund;

   //constructor with parcel
   public Shop(Parcel parcel){
       name = parcel.readString();
       fund = parcel.readLong();
   }

   //normal constructor
   public Shop(Owner owner){
        name = owner.getShopName();
        fund = owner.getFund();
    }

    @Override
  public int describeContents() {
    return 0;
  }

  @Override
  public void writetoParcel(Parcel dest, int flags) {
      dest.writeString(name);
      dest.writeLong(fund);
    }

    public static final Creator<Shop> CREATOR = new Creator<Shop>(){

       @Override
       public Shop createFromParcel(Parcel parcel) {
        //use the constructor which accept parcel
        return new Shop(parcel);
       }

       @Override
       public Shop[] newArray(int size) {
        return new Shop[size];
       }

    };
}

现在,我的代码通过使用常规构造函数启动Shop实例：

Owner owner = getownerInfo();
Shop myShop = new Shop(owner); //initiate a Shop with owner

然后,我的代码将shop实例存储到Android的内部存储中：

String fileName = "shop_file";
try{
  FileOutputStream fos = activity.openFileOutput(fileName,Context.MODE_PRIVATE);
  ObjectOutputStream oos = new ObjectOutputStream(fos);         

  oos.writeObject(myShop); 
  oos.flush();
  oos.close();
}catch(Exception ex){
  ...
}

但是当运行我的应用程序时,我得到了java.io.NotSerializableException：

06-12 13:04:29.258: W/System.err(2632): java.io.NotSerializableException: com.my.app.model.Shop
06-12 13:04:29.258: W/System.err(2632):     at java.io.ObjectOutputStream.writeNewObject(ObjectOutputStream.java:1364)
06-12 13:04:29.266: W/System.err(2632):     at java.io.ObjectOutputStream.writeObjectInternal(ObjectOutputStream.java:1671)
06-12 13:04:29.266: W/System.err(2632):     at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:1517)

为什么？我哪里错了？

解决方法:

从执行看来,您正在尝试序列化未实现Serializable的CartData实例：

java.io.NotSerializableException: com.my.app.model.Shop

如果要序列化,则应让Shop implemensts Serializable

从doc开始

Parcel is not a general-purpose serialization mechanism. This class
(and the corresponding Parcelable API for placing arbitrary objects
into a Parcel) is designed as a high-performance IPC transport. As
such, it is not appropriate to place any Parcel data in to persistent
storage: changes in the underlying implementation of any of the data
in the Parcel can render older data unreadable.
