Java 序列化基础知识

class Person implements Serializable {

            // 序列化步骤，新建一个 ObjectOutputStream 镀锡
            ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("object.txt"));

            // 序列化 写入对象
            oos.writeObject(person);

            // 反序列化 新建一个ObjectInputStream
            ObjectInputStream ois = new ObjectInputStream(new FileInputStream("object.txt"));
            // 反序列化 读取
            Person per = (Person) ois.readObject();
