What is the JPA entity lifecycle?

Can you explain the JPA entity lifecycle?

Sure! The JPA entity lifecycle consists of several states: transient, persistent, detached, and removed.

What happens in the transient state?

In the transient state, the entity is created but not yet associated with a persistence context, meaning it won't be stored in the database.

And what about the persistent state?

In the persistent state, the entity is managed by the EntityManager, and any changes made to it are automatically synchronized with the database.

How does an entity become detached?

An entity becomes detached when the EntityManager that was managing it is closed or when the entity is explicitly removed from the persistence context.
