在Java中,可以通过以下几种方式实现深度克隆对象:
import java.io.*;
public class DeepClone implements Serializable {
public Object clone() {
try {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(bos);
oos.writeObject(this);
ByteArrayInputStream bis = new ByteArrayInputStream(bos.toByteArray());
ObjectInputStream ois = new ObjectInputStream(bis);
return ois.readObject();
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
}
public class DeepClone implements Cloneable {
private int value;
private ReferenceType reference;
public DeepClone(int value, ReferenceType reference) {
this.value = value;
this.reference = reference;
}
public Object clone() throws CloneNotSupportedException {
DeepClone cloned = (DeepClone) super.clone();
cloned.reference = (ReferenceType) reference.clone();
return cloned;
}
}
import org.apache.commons.lang3.SerializationUtils;
public class DeepClone {
private int value;
private ReferenceType reference;
public DeepClone(int value, ReferenceType reference) {
this.value = value;
this.reference = reference;
}
public DeepClone clone() {
return SerializationUtils.clone(this);
}
}
需要注意的是,无论使用哪种方式,被克隆的对象及其引用的类都需要实现Cloneable接口或Serializable接口,并确保引用的类也能正确进行克隆。
