Create save-only property in JPA/Hibernate

Question

I'm adding a property to existing DTO. The property is intended to be used only from the database. It means it will be stored only. There will be no usages of it across our application. It is needed for our Product Owner to make reports. I would like to make it store-only i.e. to be stored but never retrieved from the database. Is there such an opportunity in JPA/Hibernate? Thanks for any help!

@Akshay Thanks, I'm just being stupid today. I've just implemented it. lazy fetch type + no getter — Dmitry Senkovich

Add only setters but never getters for that specific property. Also considering the object serialization to xml or json pay attention in excluding that specific field from being serialized.

Yes + lazy fetching

Actually, the answer was too easy. I ended up with not adding getter for the property and specifying @Basic(fetch = FetchType.LAZY) on the property.

UPDATE: It works only with getter.
