Hibernate中cascade为all-delete-orphan与all的区别

HrStaffBaseInfo与HrStaffSocietyRelation为one to many关系。

若级联关系cascade设置为all，则通过hrStaffBaseInfo.removeHrStaffSocietyRelationDetail(relationId);只是使hrStaffSocietyRelation成为了一个孤儿，并不能将hrStaffSocietyRelation在数据库中对应的数据也被删除，但其他的新增、更新可以。但若级联关系cascade设置为all-delete-orpnan，则可以删除，且新增、更新亦可。

注：

all：所有情况下均进行级联操作。

all-delete-orpnan：当被关联对象失去宿主时，将其级联删除。

removeHrStaffSocietyRelationDetail函数：

/**

* remove a HrStaffSocietyRelation detail by relationId

* @param relationId

*/

public void
removeHrStaffSocietyRelationDetail(String relationId) {

for (HrStaffSocietyRelation hrStaffSocietyRelation :
getHrStaffSocietyRelations()) {

if
(hrStaffSocietyRelation.getRelationId().equals(relationId)) {

getHrStaffSocietyRelations().remove(hrStaffSocietyRelation);

break;

}

}

}
