Difference Between Hibernate Save And Persist Methods
Actually the difference between hibernate save() and persist() methods is depends on generator class we are using.
- If our generator class is assigned, then there is no difference between save() and persist() methods. Because generator ‘assigned’ means, as a programmer we need to give the primary key value to save in the database right [ Hope you know this generators concept ]
- In case of other than assigned generator class, suppose if our generator class name is Increment means hibernate it self will assign the primary key id value into the database right [ other than assigned generator, hibernate only used to take care the primary key id value remember ], so in this case if we call save() or persist() method then it will insert the record into the database normally
But here thing is, save() method can return that primary key id value which is generated by hibernate and we can see it by
long s = session.save(k);
In this same case, persist() will never give any value back to the client, hope you are clear.
