java对象序列化与反序列化的实现

一、首先创建一个java对象，实现序列化接口，为序列化和反序列化做准备

import java.io.Serializable;

/**
 * 实现序列化接口，为序列化和反序列化测试做准备
 */
public class Car implements Serializable {

    private int height;

    private String color;

    public Car(int height, String color) {
        this.height = height;
        this.color = color;
    }

    @Override
    public String toString() {
        return "Car{" +
                "height=" + height +
                ", color='" + color + '\'' +
                '}';
    }

}

 

二、编写测试类，编写实现序列化和反序列化的代码

import java.io.*;

public class SerializableTest {

    public static void main(String[] args) throws IOException, ClassNotFoundException {
        //序列化过程，文件后缀可以随意
        ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("car1.ser"));
        Car car1 = new Car(175, "白色");
        oos.writeObject(car1);
        oos.close();

        //反序列化过程
        ObjectInputStream ois = new ObjectInputStream(new FileInputStream("car1.ser"));
        Car car2 = (Car) ois.readObject();
        System.out.println("car2:" + car2);
        ois.close();
    }

}

三、单独运行序列化代码和反序列化代码即可得到测试结果

car2:Car{height=175, color='白色'}
