问题
I have 3 tables in Oracle (10g).
- Zone
- Weight
- ZoneCharge
Where ZoneCharge has a composite primary key(zoneId, weightId) which references to primary keys of the Zone and the Weight tables.
I need to delete all the rows from the ZoneCharge table based on the zoneId supplied (the weightIds are unknown in this case).
The native Oracle SQL to achieve this would be as simple as follows.
DELETE FROM zone_charge WHERE zone_id=22;
I have tried the following way (in DAO).
@Override
@SuppressWarnings("unchecked")
@Transactional(readOnly=false, propagation=Propagation.REQUIRES_NEW)
public void delete(Long id)
{
Session session=sessionFactory.openSession();
session.beginTransaction();
Zone zone=(Zone) session.get(Zone.class, id);
Set<ZoneCharge> zoneChargeSet = zone.getZoneChargeSet();
int i=1;
for(ZoneCharge zoneCharge:zoneChargeSet)
{
ZoneChargePK zoneChargePK=new ZoneChargePK();
zoneChargePK.setZoneId(id);
zoneChargePK.setWeightId(zoneCharge.getWeight().getWeightId());
zoneCharge.setZoneChargePK(zoneChargePK);
session.delete(zoneCharge);
if(i++%50==0)
{
i=1;
session.flush();
session.clear();
}
}
session.getTransaction().commit(); //The exception is caused at this line.
session.close();
}
It caused the following exception.
org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations): [model.ZoneCharge#tempPackage.ZoneChargePK[zoneId=22, weightId=164]]
The stacktrace:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations): [model.ZoneCharge#tempPackage.ZoneChargePK[zoneId=22, weightId=164]]

回答1:
Somewhere have to be an association to that object (List, Map, Set, etc...) you have to remove that Object from there first before you can delete it.
Simular question was asked here: deleted object would be re-saved by cascade (remove deleted object from associations)
