Hibernate Tip: How to delete child entities from a many-to-one association

Показать описание

For some many-to-one associations, the child entity can’t exist without its parent. A typical example is the OrderItem which can’t exist without the Order. When you remove the association between the OrderItem and the Order, you need to delete that OrderItem entity as well. So, what’s the easiest way to implement that?

The JPA specification provides the orphanRemoval feature for these use cases. When you activate it on the association, Hibernate removes a child entity when you remove its association to the parent entity.

So book Id with 1 also delete ??
Why we aren't deleting directly book with id 1 and it should automatically delete all associated review object

This video is too confusing, you didn't show the class definition of child at all.. Its hard to understand by just looking a parent class definition
