java深拷贝

下面通过序列化实现深拷贝
public class YuelyLog implements Serializable,Cloneable {
private Attachment attachment;
private String name;
private String date;

@Override
protected YuelyLog clone() throws CloneNotSupportedException {
    return (YuelyLog)super.clone();
}

public Attachment getAttachment() {
    return attachment;
}

public void setAttachment(Attachment attachment) {
    this.attachment = attachment;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getDate() {
    return date;
}

public void setDate(String date) {
    this.date = date;
}

/**
 * 使用序列化技术实现深拷贝
 * @return
 */
public YuelyLog deepClone() throws IOException,ClassNotFoundException{
    //将对象写入流中
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    ObjectOutputStream objectOutputStream = new ObjectOutputStream(outputStream);
    objectOutputStream.writeObject(this);
    //从流中取出
    ByteArrayInputStream inputStream = new ByteArrayInputStream(outputStream.toByteArray());
    ObjectInputStream objectInputStream = new ObjectInputStream(inputStream);
    return (YuelyLog)objectInputStream.readObject();

}

}
