我正在尝试序列化然后反序列化多个对象。我可以毫无问题地写入文件,但在选择deserialize选项时,我得到以下堆栈跟踪。以前我可以成功地序列化和反序列化一个对象。
dos中的堆栈跟踪是:
java.io.EOFException
at java.io.ObjectInputStream$BlockDataInputStream.peekByte(Unknown Sourc
e)
at java.io.ObjectInputStream.readObject0(Unknown Source)
at java.io.ObjectInputStream.readObject(Unknown Source)
at mainmenutest.DeserializeDemo.Deserialize(DeserializeDemo.java:23)
at mainmenutest.MainmenuTest.getInput(MainmenuTest.java:64)
at mainmenutest.MainmenuTest.main(MainmenuTest.java:26)
我的反序列化代码如下:
package mainmenutest;
/**
*
* @author Darren Estcourt
*/
import java.io.*;
public class DeserializeDemo
{
public void Deserialize()
{
ClubInfo club = null;
ClubInfo club2 = null;
try
{
FileInputStream fileIn = new FileInputStream("C:/tmp/club.ser");
ObjectInputStream in = new ObjectInputStream(fileIn);
club = (ClubInfo) in.readObject();
club2 = (ClubInfo) in.readObject();
in.close();
fileIn.close();
}catch(IOException i)
{
i.printStackTrace();
return;
}catch(ClassNotFoundException c)
{
System.out.println("Club class not found");
c.printStackTrace();
return;
}
System.out.println("Saved game loaded...");
System.out.println("Name: " + club.teamName);
System.out.println("Stadium: " + club.stadium);
System.out.println("Division: " + club.division);
// System.out.println("SSN: " + club.SSN);
System.out.println("Stadium Capacity: " + club.stadiumCapacity);
System.out.println("Name : " + club2.teamName);
}
}
我不希望有人为我修理它,只是指向正确的方向。我计划最终反序列化大约20个对象。
答案 0 :(得分:1)
EOFException
(零长度,它被截断,关闭时没有正确刷新)
在这种情况下,readObject()
引发了异常,因此只有第一个适用。看起来你要么序列化没有对象并试图读取一个对象,要么序列化一个对象并试图读取两个。
