我在嘗試發送以下內容,但在下面出現以下錯誤消息。 TableUser實現可序列化,但似乎問題是FXCollections,但我不知道如何序列化。java.io.NotSerializableException異常問題
這裏是TableUser類。
package application;
import java.io.Serializable;
public class TableUser implements Serializable{
private static final long serialVersionUID = 1L;
private String username = "";
public TableUser(String name) {
this.username = name;
}
public String getUsername(){
return username;
}
public void setUsername(String user){
username = user;
}
}
//NOT apart of TableUser - This is the code that isn't working
private static ObservableList<TableUser> clientList = FXCollections.observableArrayList();
Object[] data = new Object[2];
data[0] = "CLIENTS";
data[1] = clientList;
for(int i = 0; i < clients.size(); i++){
clients.get(i).sendData(data);
}
//I don't know if this helps but here is the sendData method
protected void sendData(Object[] data){
try {
oos.writeObject(data); //ServerMultiClient.java:286
oos.reset();
} catch (IOException e) {
e.printStackTrace();
}
}
//This is from the Client application that is also part of the issue
if((fromServer = (Object[]) ois.readObject()) != null){ //Controller.java:109

,xmlEncoder適用於可觀察列表。我將它們編碼爲zip文件,以獲得大小和速度。你可能不得不改變私人靜態,我不記得了。 – brian
