• Memento
• 快照
• Java序列化, ProtoBuf库

  • class C implements Serializable {
        private transient List<Object> list;
    }
    ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(new File("")));
    oos.writeObject(o1)
    oos.writeObject(o2)
    ObjectInputStream ois = new ObjectInputStream(new FileInputStream(new File("")));
    o1 = ois.readObject();
    o2 = ois.readObject();
