Understanding the Differences between Hibernate's persist() and save() Methods

In the context of Hibernate, the question arises: what are the key differences between the persist() and save() methods?

Persist vs Save in Hibernate

The persist() method is used to make a transient instance of an object persistent. However, it does not immediately guarantee the assignment of an identifier value to the object. The assignment may occur during flush time, which might differ from the immediate time of invocation.

Additionally, persist() ensures that an INSERT statement is not executed if it is called outside of transaction boundaries. This functionality is particularly useful in situations where there are long-running conversations involving an extended Session or persistence context.

On the other hand, the save() method does not offer the same guarantees as persist(). It returns an identifier and immediately executes an INSERT query to obtain the identifier, even if it is called outside of transaction boundaries. This can be problematic in long-running conversations, as mentioned earlier.
