Spring Auditing - How does spring insert @CreatedDate and @LastModifiedDate into database automaticaly?

Question

I am trying to figure out how Spring inserts the createdDate and lastModifiedDate automatically when auditing is configured. I have looked over the reference docs for Spring Data JPA but they only explain how to configure auditing. So how does this work behind the scenes?

I am asking this so I could insert extra auditing data like IP-Address of the user the same way.

Answer 1

Spring data commons has class AuditingHandler , which is responsible for populating createdDate and lasModifiedDate .

You should go-ahead check this link for class definiton and check below methods:

1. setDateTimeForNow
2. setModifyOnCreation
3. touchDate
