Master Hibernate and JPA with Spring Boot in 100 Steps - Step 77 - JPA Entity Life Cycle Methods

The video tutorial explains the use of entity lifecycle hooks and annotations in managing database operations. It covers various hooks like pre remove, post load, post persist, post remove, post update, pre persist, pre remove, and pre update. Each hook is described in terms of its function and timing in the entity lifecycle, such as when an entity is loaded, persisted, removed, or updated. The tutorial emphasizes the importance of these hooks in ensuring data integrity and consistency during database operations.

What is the primary purpose of using a pre-remove hook in entity lifecycle management?

• To load the entity after it is retrieved

• To update the entity after it is modified

• To persist the entity to the database

• To update the entity's 'is deleted' attribute before deletion

Which annotation is triggered immediately after an entity is loaded from the database?

• Pre update

• Post load

• Post persist

• Pre remove

When is the post-persist method called in the entity lifecycle?

• Before the entity is persisted

• After the entity is persisted to the database

• After the entity is removed

• Before the entity is updated

Which lifecycle annotation is used just before an entity is updated?

• Pre load

• Post remove

• Pre update

• Post update

What is the role of pre-persist in the entity lifecycle?

• To remove an entity before deletion

• To update an entity before modification

• To prepare an entity before it is persisted

• To load an entity after retrieval
