如何避免在更新hibernate中的父级时更新子对象？

Question

我不知道我的设计本身是错的还是什么。但任何机构可以给我一个解决方案。 我有一个Object，PlanningItem。从这我需要通过使用PlanningItem的两个属性获取记录形成另一个表。所以我创建了视图并在PlanningItem中将该视图添加为多个关系记录。当我更新计划项目时，我收到错误消息。 在此我准备将视图改为和再选择或其他任何东西。请提出建议继续。

以下是我的代码。

ViewPlannigItem.hbm.xml

<class 
     name="com.cotyww.ipmasterdata.core.entity.master.ViewPlannigItem" 
     table="VW_PLANNING_ITEM" > 
     <id name="planningIrc" type="string" column="PLANNING_IRC"> 
      <generator class="assigned" /> 
     </id> 

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


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


     <property name="salesOrgId" column="SALES_ORG_ID" 
      type="integer" /> 

     <property name="salesBrandId" column="SALES_BRAND_PKEY" 
      type="integer" /> 

     <many-to-one name="salesBrand" update="false" insert="false" 
      class="com.cotyww.ipmasterdata.core.entity.master.SalesBrand" 
      column="SALES_BRAND_PKEY" /> 

     <many-to-one name="salesOrg" update="false" insert="false" 
      class="com.cotyww.ipmasterdata.core.entity.master.SalesOrg" 
      column="SALES_ORG_ID" /> 

    </class>

      <filter name="planningsalesORg" 
       condition="SALES_ORG_ID = :salesOrgId" /> 
     </set>

     <property name="createdBy" column="Created_By" type="string" /> 
     <property name="createdDate" column="Created_Date" type="date" /> 

    </class> 
    <sql-query name="nextPlanningItemSequenceValueC1US">

数据库查看

CREATE OR REPLACE FORCE VIEW COREMASTER.VW_PLANNING_ITEM 
(PLANNING_IRC, PLANNING_ITEM_DESC, PROGRAM_ID, SALES_ORG_ID, SALES_BRAND_PKEY, 
GMM_HIERARCHY_CODE) 
AS 
SELECT P.PLANNING_IRC, 
      P.PLANNING_ITEM_DESC, 
      P.PROGRAM_ID, 
      nvl(MAP.SALES_ORG_ID,MAP1.SALES_ORG_ID) as sales_org, 
      nvl(MAP.SALES_BRAND_PKEY,MAP1.SALES_BRAND_PKEY) as sales_brand_pkey, 
      P.GMM_HIERARCHY_CODE 
    FROM PLANNING_ITEM P, 
      GMM_MAP MAP, 
      GMM_MAP MAP1  
    WHERE 
      P.GMM_HIERARCHY_CODE = MAP.GMM_HIERARCHY_CODE(+) 
      AND P.CATEGORY_CODE = Map.GMM_CATEGORY_CODE(+) 
      AND P.GMM_HIERARCHY_CODE = MAP1.GMM_HIERARCHY_CODE(+) 
      AND Map1.GMM_CATEGORY_CODE IS NULL; 

Answer 1

尝试在一个一对多的关系的一侧设置参数inverse =“true”。这会告诉hiberante在更新父级时不更新关系（FK列）。

我的意思是未来：

<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>

这不是你该怎么一般使用Hibernate。将您的对象直接与相关表关联，然后可以定义查询以使用您放入视图中的筛选等来获取它们。我建议您阅读JPQL查询JPA对象。
