我不知道我的设计本身是错还是什么。但任何机构都可以给我一个解决方案。 我有一个Object,PlanningItem。从这里我需要通过使用PlanningItem的两个属性从另一个表中获取记录。所以我创建了视图,并将该视图添加为PlanningItem中的一对多关系记录。当我更新规划项目时,我收到错误。 在此我准备将视图更改为subselect或其他任何内容。请建议继续这个想法。
以下是我的代码。
ViewPlannigItem.hbm.xml

尝试设置关系参数inverse =“true”的一对多方面。这将告诉hiberante在更新父级时不要更新关系(FK列)。
我的意思是下一个:
<set name="lstViewPlanningItem" cascade="none" inverse="true">
<key column="PLANNING_IRC" />
<one-to-many not-found="ignore"
class="com.cotyww.ipmasterdata.core.entity.master.ViewPlannigItem" />
<filter name="planningsalesORg"
condition="SALES_ORG_ID = :salesOrgId" />
</set>

这不是你通常使用Hibernate的方式。将您的对象直接与相关表格相关联,然后您可以定义查询以使用您在视图中放置的过滤等来获取它们。我建议阅读JPQL以查询JPA对象。
