Java之序列化和反序列化的示例分享

Java中的序列化和反序列化过程中
    使用的方法是ObjectOutputStream 和 ObjectInputStream
		 ObjectOutputStream:
		   用于将对象序列化为字节流
		 ObjectInputStream:
		   用于将字节流反序列化为对象

import java.io.*;
 
public class SerializationExample {
    public static void main(String[] args) {
        // 创建对象
        Person person = new Person("java265",18);
 
        // 序列化对象
        try {
            FileOutputStream fileOut = new FileOutputStream("person.ser");
            ObjectOutputStream out = new ObjectOutputStream(fileOut);
            out.writeObject(person);
            out.close();
            fileOut.close();
            System.out.println("序列化成功");
        } catch (IOException ex) {
            ex.printStackTrace();
        }
 
        // 反序列化对象
        try {
            FileInputStream fileIn = new FileInputStream("person.ser");
            ObjectInputStream in = new ObjectInputStream(fileIn);
            Person obj = (Person) in.readObject();
            in.close();
            fileIn.close();
            System.out.println("反序列化成功");
            System.out.println("读取对象：" + obj);
        } catch (IOException ex) {
            ex.printStackTrace();
        } catch (ClassNotFoundException ex) {
            ex.printStackTrace();
        }
    }
}
 
// 实现 Serializable 接口
class Person implements Serializable {
    private static final long serialVersionUID = 1L;
 
    private String name;
    private int age;
 
    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }
 
    public String getName() {
        return name;
    }
 
    public int getAge() {
        return age;
    }
 
    @Override
    public String toString() {
        return "Person [name=" + name + ", age=" + age + "]";
    }
}
