存储两次序列化对象，读取报错问题
java.io.StreamCorruptedException: invalid type code: A

原因：
对象序列化存储时，每次写入文件都会存放head头信息，每次写入的head信息不一致，所有读取head信息会报错

解决：
自己写 MyObjectInputStream/MyObjectOutputStream 类，分别继承ObjectInputStream和ObjectOutputStream，重写readStreamHeader()和writeStreamHeader()方法，直接return，不做任何处理

序列化类：

import java.io.IOException;import java.io.ObjectOutputStream;import java.io.OutputStream;public class MyObjectOutputStream extends ObjectOutputStream{    public MyObjectOutputStream(OutputStream out) throws IOException {        super(out);        // TODO Auto-generated constructor stub    }    @Override    protected void writeStreamHeader() throws IOException {        // TODO Auto-generated method stub        return;    }}

反序列化类：

import java.io.IOException;import java.io.InputStream;import java.io.ObjectInputStream;import java.io.StreamCorruptedException;public class MyObjectInputStream extends ObjectInputStream{    public MyObjectInputStream(InputStream in) throws IOException {        super(in);        // TODO Auto-generated constructor stub    }    @Override    protected void readStreamHeader() throws IOException,            StreamCorruptedException {        // TODO Auto-generated method stub        return;    }   }

把他们当 ObjectInputStream/ObjectOutputStream 使用就行

MyObjectInputStream mi = new MyObjectInputStream(new FileInputStream(file));
