Whats the difference between persist() and save() in Hibernate?

Question

Through documentation i can find only one difference that is save method generates returns the object as generated identifier but persist does not.Is it the only purpose for

Answer 1

save() returns an identifier, and if an INSERT has to be executed to get the identifier, this INSERT happens immediately, no matter if you are inside or outside of a transaction. This is not good in a long-running conversation with an extended Session/persistence context.

persist() is used on transient objects. It makes a transient instance persistent. However, it doesn't guarantee that the identifier value will be assigned to the persistent instance immediately, the assignment might happen at flush time.It also guarantees that it will not execute an INSERT statement if it is called outside of transaction boundaries. This is useful in long-running conversations with an extended Session/persistence context.
