Difference between save and persist.

Save()

1. Returns generated Id after saving. The return type is serializable.
2. Saves the value to DB immediately and keeps track of the entity until the end of the session(I have tried to change the entity values outside of the transaction, it does not show any effect when session commits)
3. Does not save the changes to the db outside of the transaction.
4. Assigns the generated id to the entity you are persisting
5. Session.save() for a detached object will create a new row in the table.

Persist()

1. Does not returns generated Id after saving. Its void return type.
2. Saves the value to DB immediately and keeps track of the entity until the end of the session.(I have tried to change the entity values outside of the transaction, it does not show any effect when session commits)
3. Does not save the changes to the db outside of the transaction.
4. Assigns the generated id to the entity you are persisting
5. session.persist() for a detached object will throw PersistentObjectException as it is not allowed.
