我有父对象（DDetails），它包含7个子对象（DPricingElements，DCoverages，DElectricalLimit，DVehicleDetails，DAttributes，DNonElecLimit，DPartyDetails），我正在删除将删除子对象的父对象。使用以下代码，
Query query = session.createQuery("FROM DDetails where DQuote.Id =:Id").setParameter("Id", Id);
List<DDetails> quertList = query.list();
session.delete(dDetails);
它也删除了孩子和父母，一些罕见的情况我得到了一个异常 org.hibernate.ObjectDeletedException：已删除的对象将被cascade重新保存（从关联中删除已删除的对象）：[com.model.DDetails＃ 257309]
我想知道级联协会，但是上面的代码在生产上运行了2年多。无法产生相同的异常，异常得到了测试，UAT环境。
请查找日志跟踪;

在org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations):的帮助下，我改变了代码，但仍然有同样的异常。
for (DDetails dDetails: quertList) {
if (dDetails.getDNonElecLimits() != null && !dDetails.getDNonElecLimits().isEmpty()) {
for (DNonElecLimit a: new ArrayList < DNonElecLimit > (dDetails.getDNonElecLimits())) {
dDetails.getDNonElecLimits().remove(a);
//session.delete(a);
}
}
if (dDetails.getDElectricalLimits() != null && !dDetails.getDElectricalLimits().isEmpty()) {
for (DElectricalLimit b: new ArrayList < DElectricalLimit > (dDetails.getDElectricalLimits())) {
dDetails.getDElectricalLimits().remove(b);
//session.delete(b);
}
}
if (dDetails.getDAttributeses() != null && !dDetails.getDAttributeses().isEmpty()) {
for (DAttributes c: new ArrayList < DAttributes > (dDetails.getDAttributeses())) {
dDetails.getDAttributeses().remove(c);
}
}
if (dDetails.getDCoverageses() != null && !dDetails.getDCoverageses().isEmpty()) {

}
if (dDetails.getDPricingElementses() != null && !dDetails.getDPricingElementses().isEmpty()) {

dDetails.getDPricingElementses().remove(e);
}
}
if (dDetails.getDVehicleDetailses() != null && !dDetails.getDVehicleDetailses().isEmpty()) {
for (DVehicleDetails f: new ArrayList < DVehicleDetails > (dDetails.getDVehicleDetailses())) {
dDetails.getDVehicleDetailses().remove(f);
}
}
if (dDetails.getDThirdPartyDetailses() != null && !dDetails.getDThirdPartyDetailses().isEmpty()) {
for (DThirdPartyDetails g: new ArrayList < DThirdPartyDetails > (dDetails.getDThirdPartyDetailses())) {
dDetails.getDThirdPartyDetailses().remove(g);

}
session.delete(dDetails);
session.flush();
}

它也删除了孩子和父母，一些罕见的情况我得到了 异常org.hibernate.ObjectDeletedException：删除的对象会 通过级联重新保存（从关联中删除已删除的对象）： [com.model.DDetails＃257309]
那是因为，有时候，你有一个父实体阻止对DDetails级联的引用，并且你没有清除该引用。
同时，一个简单的解决办法就是做这样的事情：
session.clear();
session.createQuery("delete from DDetails where DQuote.Id =:Id")
.setParameter("Id", Id)
.executeUpdate();
肯定会删除它。
