Java序列化和反序列

首先先定义一个user类需继承Serializable

package test;



import java.io.IOException;

import java.io.Serializable;



public class user implements Serializable {

    private String name;



    public String getName() {

        return name;

    }



    public void setName(String name) {

        this.name = name;

    }



}   



编写一个测试类，生成一个user对象，将其序列化后的字节保存在硬盘上，然后再读取被序列化后的字节，将其反序列化后输入user的name属性

package test;



import java.io.FileInputStream;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.ObjectInputStream;

import java.io.ObjectOutputStream;



public class test1 {

    public static void main(String[] args) {

        try {

            FileOutputStream out =new FileOutputStream("d:/1.bin");

            ObjectOutputStream obj_out = new ObjectOutputStream(out);

            user u = new user();

            u.setName("test");

            obj_out.writeObject(u);



            //利用readobject方法还原user对象

            FileInputStream in = new FileInputStream("d:/1.bin");

            ObjectInputStream ins = new ObjectInputStream(in);

            user u1 = (user)ins.readObject(); 



            System.err.println(u1.getName());

        } catch (FileNotFoundException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        } catch (IOException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        } catch (ClassNotFoundException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }



    }

}
