如何在Java中实现对象的深拷贝机制

import java.io.*;

public class DeepCopyUtil {
    public static <T extends Serializable> T deepCopy(T object) {
        try {
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            ObjectOutputStream oos = new ObjectOutputStream(bos);
            oos.writeObject(object);
            oos.flush();
            oos.close();

            ByteArrayInputStream bis = new ByteArrayInputStream(bos.toByteArray());
            ObjectInputStream ois = new ObjectInputStream(bis);
            return (T) ois.readObject();
        } catch (IOException | ClassNotFoundException e) {
            throw new RuntimeException("深拷贝失败", e);
        }
    }
}

class Address implements Cloneable {
    private String city;

    public Address(String city) {
        this.city = city;
    }

    @Override
    protected Address clone() {
        return new Address(this.city); // 基本类型直接复制
    }
}

class Person implements Cloneable {
    private String name;
    private Address address;

    public Person(String name, Address address) {
        this.name = name;
        this.address = address;
    }

    @Override
    protected Person clone() {
        Address clonedAddress = this.address.clone(); // 深拷贝引用对象
        return new Person(this.name, clonedAddress);
    }
}

import com.google.gson.Gson;

Gson gson = new Gson();
Person copied = gson.fromJson(gson.toJson(originalPerson), Person.class);
