    System.out.println("Before Serialization:" + user);
    ByteArrayOutputStream buf = new ByteArrayOutputStream();
   
    //把User对象序列化到一个字节缓存中
    ObjectOutputStream o =new ObjectOutputStream(buf);
    o.writeObject(user);
      
    //从字节缓存中反序列化User对象
    ObjectInputStream in =new ObjectInputStream(
          new ByteArrayInputStream(buf.toByteArray()));
    user= (User)in.readObject();
    System.out.println("After Serialization:" + user);
   }
}
