java - 如何避免在 hibernate 中更新父对象时更新子对象？

Question

我不知道是我的设计本身有问题还是什么。但任何人都可以给我一个解决方案吗？我有一个对象，PlanningItem。由此，我需要使用 PlanningItem 的两个属性从另一个表获取记录。所以我创建了 View ，并将该 View 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。在这里，我准备将 View 更改为子选择或其他任何内容。请提出继续的想法。

下面是我的代码。

ViewPlannigItem.hbm.xml

        table="VW_PLANNING_ITEM"  >

            <generator class="assigned" />
        </id>

        <property name="planningIRCDesc" column="PLANNING_ITEM_DESC"
            type="string" />


        <property name="programId" column="PROGRAM_ID" type="string" />

Answer 1

尝试在关系参数的一对多方面设置 inverse="true"。这将告诉 hiberante 在更新父级时不要更新关系(FK 列)。

我的意思是下一步:

<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>
