您必须首先使用常规ObjectOutputStream编写流头，否则在使用ObjectInputStream打开文件时会得到java.io.StreamCorruptedException。
public class Test1 implements Serializable { public static void main(String[] args) throws Exception { ObjectOutputStream os1 = new ObjectOutputStream(new FileOutputStream("test")); os1.writeObject(new Test1()); os1.close(); ObjectOutputStream os2 = new ObjectOutputStream(new FileOutputStream("test", true)) { protected void writeStreamHeader() throws IOException { reset(); } }; os2.writeObject(new Test1()); os2.close(); ObjectInputStream is = new ObjectInputStream(new FileInputStream("test")); System.out.println(is.readObject()); System.out.println(is.readObject());
