如何避免在更新hibernate中的父級時更新子對象？

Question

我不知道我的設計本身是錯的還是什麼。但任何機構可以給我一個解決方案。 我有一個Object，PlanningItem。從這我需要通過使用PlanningItem的兩個屬性獲取記錄形成另一個表。所以我創建了視圖並在PlanningItem中將該視圖添加爲多個關係記錄。當我更新計劃項目時，我收到錯誤消息。 在此我準備將視圖改爲和再選擇或其他任何東西。請提出建議繼續。

以下是我的代碼。

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"

     <many-to-one name="salesOrg" update="false" insert="false"

Answer 1

嘗試在一個一對多的關係的一側設置參數inverse =「true」。這會告訴hiberante在更新父級時不更新關係（FK列）。

我的意思是未來：

<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>

這不是你該怎麼一般使用Hibernate。將您的對象直接與相關表關聯，然後可以定義查詢以使用您放入視圖中的篩選等來獲取它們。我建議您閱讀JPQL查詢JPA對象。
