How does @CreatedBy work in Spring Data JPA?

Question

I used the @CreatedDate entity property and I see that it inserts a date in db. I don't understand what the purpose of the @CreatedBy annotation in Spring Data JPA is.

In the reference documentation, I read:

We provide @CreatedBy , @LastModifiedBy to capture the user who created or modified the object.

But how to create and use such a user?

If you’ve already turned to the help documentation, I recommend reading two more paragraphs to learn how to use AuditorAware :)
