Java对象的序列化和反序列化

对象的序列化是指将对象转换为字节序列的过程

对象的反序列化是指将字节序列恢复对象的过程

主要有两种用途:

1、把对象的字节序列永久地保存在硬盘上,通常放在一个文件中。

2、在网络上传输对象的字节序列。

Person类

package com.zyz;import java.io.Serializable;/** * Created by Administrator on 16-9-25. */public class Person implements Serializable {    private String name;    private int age;    private String sex;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public int getAge() {        return age;    }    public void setAge(int age) {        this.age = age;    }    public String getSex() {        return sex;    }    public void setSex(String sex) {        this.sex = sex;    }}

 

 

测试类

package com.zyz;import java.io.*;import java.text.MessageFormat;/** * Created by Administrator on 16-9-25. */public class TestObjSerializeAndDeserialize {    public static void main(String[] args){//        try {//            SerializePerson();//        } catch (IOException e) {//            e.printStackTrace();//        }        try {
       SerializePerson(); Person person
=DeserializPerson(); System.out.println(MessageFormat.format("姓名:{0},年龄:{1},性别:{2}",person.getName(),person.getAge(),person.getSex())); } catch (IOException e) { e.printStackTrace(); } catch (ClassNotFoundException e) { e.printStackTrace(); } } private static void SerializePerson() throws IOException { Person person=new Person(); person.setName("乔大爷"); person.setAge(40); person.setSex("男"); ObjectOutputStream oo=new ObjectOutputStream(new FileOutputStream(new File("d:/person.txt"))); oo.writeObject(person); System.out.println("文件序列化成功!"); oo.close(); } private static Person DeserializPerson() throws IOException, ClassNotFoundException { ObjectInputStream ois=new ObjectInputStream(new FileInputStream(new File("d:/person.txt"))); Person person=(Person)ois.readObject(); System.out.println("Person对象反序列化成功!"); return person; }}
