标题: 序列化问题 [打印本页] 作者: 九天玄妖 时间: 2016-4-29 22:33 标题: 序列化问题 请各位帮忙这个为什么会出现这个异常？
这是异常信息
Exception in thread "main" [Person [name=张三, age=23], Person [name=李四, age=24], Person [name=王五, age=25]]
java.io.EOFException
at java.io.ObjectInputStream$BlockDataInputStream.peekByte(Unknown Source)
at java.io.ObjectInputStream.readObject0(Unknown Source)
at java.io.ObjectInputStream.readObject(Unknown Source)
at byron.darkhorse.day22.Demo_ObjectInputStream.main(Demo_ObjectInputStream.java:15)
下面我帖出代码，麻烦大神帮忙分析下，谢谢。
public class Demo_ObjectOutputStream {
public static void main(String[] args) throws FileNotFoundException, IOException {
Person p1 = new Person("张三",23);
Person p2 = new Person("李四",24);
Person p3 = new Person("王五",25);
ArrayList<Person> list = new ArrayList<>();
list.add(p1);
list.add(p2);
list.add(p3);
ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("person.txt"));
oos.writeObject(list);
oos.close();
}
}
public class Demo_ObjectInputStream {
@SuppressWarnings("unchecked")
public static void main(String[] args) throws FileNotFoundException, IOException, ClassNotFoundException {
ObjectInputStream ois = new ObjectInputStream(new FileInputStream("person.txt"));
System.out.println(ois.readObject());
ArrayList<Person> list = (ArrayList<Person>) ois.readObject();
for (Person person : list) {
System.out.println(person);
}
ois.close();
}
}
public class Person implements Serializable{
