BeanUtils.cloneBean() deep copy

问题

If all the objects within the bean implement Serializable interface, will BeanUtils.cloneBean() do a deep copy?

回答1:

No, cloneBean() does shallow copy only. If you want deep copy. You may refer this link which has technique to do deep copy.

回答2:

Use SerializationUtils.clone method from the Apache Commons Lang for the deep copy. It copies the entire class hierarchy.

SerializationUtils.clone(object);

回答3:

There is also another java library which supports both shallow cloning and deep cloning. It offers deep cloning without the need to implement Serializable.
