RMI JavaFX 2 - NotSerializableException錯誤

我想在JavaFX 2項目中使用Java RMI發送對象，但是當下面的代碼運行時它返回一個NotSerializableException。RMI JavaFX 2 - NotSerializableException錯誤

我的Admin類是可序列化的，超級類也是如此。但是，它似乎是指向Admin類中的JavaFX SimpleIntegerProperty字段的例外。

我不知道該從這裏做什麼，因爲通過RMI發送的類是可序列化的。任何幫助非常感謝。

ObservableList<Admin> data = null; 
try 
{ 
    data = FXCollections.observableArrayList(Main.docServer.getAllAdmins()); 
} 
catch (RemoteException e) 
{ 
    e.printStackTrace(); 
}

錯誤我收到：

類通過RMI發送的序列化

若延續這只是序列化Serializable或Externalizable和所有的非靜態非瞬態成員變量也這樣做等遞歸直到關閉。在這種情況下，你顯然有javafx.beans.property.SimpleIntegerProperty類型，其作爲異常告訴你的一個不可序列化：

java.io.NotSerializableException: javafx.beans.property.SimpleIntegerProperty

所以這是指它直接或間接的任何類，是不是序列化無論是。

我將Serializable類中的字段更改爲Strings和ints，並在客戶端需要時創建Simple ***** Property，並使用getters作爲參數。不是最乾淨的代碼，但它的工作原理。謝謝。 – 2013-03-01 20:30:14

您可能標誌着一個成員變量不能被序列化。並添加到類新的int字段。

private int variableInt = 0; 

private transient IntegerProperty variable; 

public IntegerProperty variableProperty() 
{ 
    if(variable == null) 
    { 
     variable = new SimpleIntegerProperty(); 
     variable.set(variableInt); 
    } 
    return variable; 
} 

public void setVariable(int variable) 
{ 
    if(this.variable != null) 
     this.variable.set(variable); 
    variableInt = variable; 
} 

public int getVariable() 
{ 
    if(variable == null) 
     return variableInt; 
    else 
     return variable.get(); 
}
