I don't understand what is the purpose of `@CreatedBy` annotation in spring data jpa.

How to use it?

I used `@CreatedDate` on entity property and I see that it inserts date into db.

Check the Auditing section of the Spring Data JPA documentation.

Thanks but it doesn't explain it well.

I want to create example project that uses `@CreatedBy`. Do you know how to use it?

It says :

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


But for me the problem is how to create such user?

Have a look at the spring data jpa auditing example. Although this seems not to use the CreatedBy annotation Luckily there are some other tutorials and blog posts providing an example here and here and here.

It has not to be a User, could be a String as well (just the user's id).
