Hibernate Tip: How to use a timestamp for versioning and optimistic locking
Показать описание
When you had to map a legacy table model in one of your projects, you probably know this situation. Instead of a numeric version column, the table model uses the timestamp of the last update. I don’t recommend using this approach because numeric versioning is much more efficient. But if you have to, you can also use a timestamp for versioning with JPA and Hibernate.
