There are other ways to do this in the db directly (rules or triggers), but those ware way slower. i feel requirement to have new instamce of interceptor per session is not un common.

Abstract Entity Persister.insert(Abstract Entity Persister.java:3079) at org.hibernate.persister.entity.

We need to overload get Current Session() method, to accept Interceptor. audit ID, user Comment to be available to call back methods of interceptor.The “Cascade” keyword is often appear on the collection mapping to manage the state of the collection automatically. ) Stock stock = new Stock(); Stock Daily Record stock Daily Records = new Stock Daily Record(); //set the stock and stock Daily Records data stock Daily Stock(stock); Stock Daily Records().add(stock Daily Records); session.save(stock); Hibernate: insert into mkyong.stock (STOCK_CODE, STOCK_NAME) values (? ) Hibernate: insert into mkyong.stock_daily_record (STOCK_ID, PRICE_OPEN, PRICE_CLOSE, PRICE_CHANGE, VOLUME, DATE) values (? How about if you just want to delete two referenced ‘stock Daily Records’ records? You need to delete the ‘stock Daily Records’ one by one.In this tutorials, this one-to-many example will be used to demonstrate the cascade effect. Stock Daily Record sdr1 = (Stock Daily Record)session.get(Stock Daily Record.class, new Integer(56)); Stock Daily Record sdr2 = (Stock Daily Record)session.get(Stock Daily Record.class, new Integer(57)); session.delete(sdr1); session.delete(sdr2); The cascade=”delete-orphan” is declared in ‘stock Daily Records’ to enable the delete orphan cascade effect.Stock stock = new Stock(); Stock Daily Record stock Daily Records = new Stock Daily Record(); //set the stock and stock Daily Records data stock Daily Stock(stock); Stock Daily Records().add(stock Daily Records); session.save(stock); session.save(stock Daily Records); Hibernate: insert into mkyong.stock (STOCK_CODE, STOCK_NAME) values (? ) Hibernate: insert into mkyong.stock_daily_record (STOCK_ID, PRICE_OPEN, PRICE_CLOSE, PRICE_CHANGE, VOLUME, DATE) values (? Both are totally different notions, see the differential here. Query q = session.create Query("from Stock where stock Code = :stock Code "); Parameter("stock Code", "4715"); Stock stock = (Stock)q.list().get(0); for (Stock Daily Record sdr : Stock Daily Records()) session.delete(stock); In above cascade delete option, if you delete a Stock , all its referenced ‘stock Daily Records’ will be deleted from database as well.
