Java之序列化和反序列化

序列化的对象：

package test_demo.SerializableOper;

import java.io.Serializable;
/*
* 序列化对象需要实现序列号接口
* */
public class Book implements Serializable {
//    指定序列化的jdk版本
//    private static final long serialVersionUID =1L;
    String name;
    int price;

    public Book(String name, int price) {
        this.name = name;
        this.price = price;
    }

    public String toString() {
        return "name: " + name + ", price: " + price;
    }
}

序列化和反序列化操作代码：

package test_demo.SerializableOper;

import java.io.*;

/*
* 序列化和反序列化举例
* 序列化：把对象保存在硬盘的过程
* 序列化的对象需要实现序列化接口
* */
public class SerializableOper {
    public static void main(String args[]) throws IOException, ClassNotFoundException {
        Book book = new Book("阿甘正传", 55);
        System.out.println(book);
        String filePath = "C:\testdata\s\book.txt";

        // 序列化
        FileOutputStream fos = new FileOutputStream(filePath);
        ObjectOutputStream oos = new ObjectOutputStream(fos);
        oos.writeObject(book);
        oos.close();
        fos.close();

        // 反序列化
        FileInputStream fis = new FileInputStream(filePath);
        ObjectInputStream ois = new ObjectInputStream(fis);
        Book b = (Book) ois.readObject();
        System.out.println(b);

    }
}

book对象序列化后保存在C: estdatasook.txt中。
