Java对象的序列化与反序列化操作详解

import java.io.Serializable;
public class User implements Serializable {    private static final long serialVersionUID = 1L;
    private String username;    private int age;
    // 构造方法、getters、setters等其他成员方法
    @Override    public String toString() {        return "User{" +                "username='" + username + '\'' +                ", age=" + age +                '}';    }}

import java.io.*;
public class SerializationExample {    public static void main(String[] args) {        try {            // 创建对象输出流            ObjectOutputStream objectOutputStream =                    new ObjectOutputStream(new FileOutputStream(new File("D://obj")));
            // 序列化对象并写入文件            objectOutputStream.writeObject(new User("lijun", 100));
            // 关闭对象输出流            objectOutputStream.close();        } catch (IOException e) {            e.printStackTrace();        }    }}

import java.io.*;
public class DeserializationExample {    public static void main(String[] args) {        try {            // 创建对象输入流            ObjectInputStream objectInputStream =                    new ObjectInputStream(new FileInputStream(new File("D://obj")));
            // 从文件中读取对象并进行反序列化            User user = (User) objectInputStream.readObject();
            // 输出反序列化后的对象            System.out.println(user);
            // 关闭对象输入流            objectInputStream.close();        } catch (IOException | ClassNotFoundException e) {            e.printStackTrace();        }    }}
