  • We should avoid save outside transaction boundary, otherwise mapped entities will not be saved causing data inconsistency. It\u2019s very normal to forget flushing the session because it doesn\u2019t throw any exception or warnings.<\/li>\n
  • Hibernate save method returns the generated id immediately, this is possible because primary object is saved as soon as save method is invoked.<\/li>\n
  • If there are other objects mapped from the primary object, they gets saved at the time of committing transaction or when we flush the session.<\/li>\n
  • For objects that are in persistent state, save updates the data through update query. Notice that it happens when transaction is committed. If there are no changes in the object, there wont be any query fired. If you will run above program multiple times, you will notice that update queries are not fired next time because there is no change in the column values.<\/li>\n
  • Hibernate save load entity object to persistent context, if you will update the object properties after the save call but before the transaction is committed, it will be saved into database.<\/li>\n<\/ul>\n
