虽然我们的条件没有得到满足，但Hibernate标准会加载所有子数据

Question

我有三个实体：

 Organization
     - Id
     - visibilityFlag
     - List<BusinessGroup> tblmorgbusinessgroups

   BusinessGroup
     - Id
     - visibilityFlag
     - orgId
     - List<BusinessHierarchy> tblmorgbusinessgrouphies

   BusinessHierarchy
     - Id
     - visibilityFlag
     - bgId

现在我想找出

的记录

org.id = "1"
org.visibilityFlag = "0"
bg.visibilityFlag = "0"
bh.visibilityFlag = "0"

我正在组织上创建crieteria，因此它正在加载BusinessGroup和BusinessHierarchy的所有记录，如果它们满足上述条件的话。

Criteria organizationDOCriteria = sessionFactory.getCurrentSession().createCriteria(OrganizationDO.class);
organizationDOCriteria.createAlias("tblmorgbusinessgroups", "businessGroup");
organizationDOCriteria.createAlias("businessGroup.tblmorgbusinessgrouphies", "businessGroupHierarchy");
organizationDOCriteria.add(Restrictions.eq("organizationid", organizationId));
organizationDOCriteria.add(Restrictions.eq("businessGroup.visibilityflag", visibilityFlag));
organizationDOCriteria.add(Restrictions.eq("businessGroupHierarchy.visibilityflag", visibilityFlag));
organizationDOCriteria.add(Restrictions.eq("visibilityflag", visibilityFlag));
Object organizationDOObj = organizationDOCriteria.uniqueResult();

我想加载具有visibilityFlag =＆＃34; 0＆＃34 ;;

的BusinessGroup /业务层次结构
