我在Oracle（10g）中有3个表。
其中ZoneCharge有一个复合主键（zoneId，weightId），它引用Zone和Weight表的主键。
我需要根据提供的ZoneCharge删除zoneId表中的所有行（在这种情况下weightIds未知）。
实现此目的的本机Oracle SQL将如下所示。
DELETE FROM zone_charge WHERE zone_id=22;
我尝试了以下方式（在DAO中）。
@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();
}
它引起了以下异常。
org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations): [model.ZoneCharge#tempPackage.ZoneChargePK[zoneId=22, weightId=164]]
stacktrace：

如果需要关联实体，则如下所示。

@Entity
@Table(name = "ZONE", catalog = "", schema = "WAGAFASHIONDB")
public class Zone implements java.io.Serializable
{
private static final long serialVersionUID = 1L;
@Id

答案 0 :(得分：2)
某处必须是该对象的关联（列表，地图，集等等），您必须先删除该对象，然后才能将其删除。
这里提出了模拟问题：deleted object would be re-saved by cascade (remove deleted object from associations)
