Java序列化和反序列化

模型类：

package com.hollischaung.serialization.SerializableDemos;
import java.io.Serializable;
/**
 * Created by hollis on 16/2/17.
 * 实现Serializable接口
 */
public class User1 implements Serializable {
 
    private String name;
    private int age;
 
    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;
    }
 
    @Override
    public String toString() {
        return "User{" +
                "name=‘" + name + ‘\‘‘ +
                ", age=" + age +
                ‘}‘;
    }
}


序列化与反序列化

package com.hollischaung.serialization.SerializableDemos;
 
import org.apache.commons.io.FileUtils;
import org.apache.commons.io.IOUtils;

import java.io.*;
/**
 * Created by hollis on 16/2/17.
 * SerializableDemo1 结合SerializableDemo2说明 一个类要想被序列化必须实现Serializable接口
 */
public class SerializableDemo1 {
 
    public static void main(String[] args) {
        //Initializes The Object
        User1 user = new User1();
        user.setName("hollis");
        user.setAge(23);
        System.out.println(user);
 
        //Write Obj to File
        ObjectOutputStream oos = null;
        try {
            oos = new ObjectOutputStream(new FileOutputStream("tempFile"));
            oos.writeObject(user);
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            IOUtils.closeQuietly(oos);
        }
 
        //Read Obj from File
        File file = new File("tempFile");
        ObjectInputStream ois = null;
        try {
            ois = new ObjectInputStream(new FileInputStream(file));
            User1 newUser = (User1) ois.readObject();
            System.out.println(newUser);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } finally {
            IOUtils.closeQuietly(ois);
            try {
                FileUtils.forceDelete(file);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
