Hibernate 단방향 부모/자식 관계 - 삭제 대신 자식 테이블에서 delete()가 수행됩니다.

Question

부모 테이블에서 레코드를 삭제하면 자식 테이블의 해당 레코드가 삭제되기를 원합니다. 널 (null)로 갱신하지 않고 Hibernate를 Child 테이블에서 h 제할 수있는 f}은 무엇입니까?

나는 최대 절전 모드 3을 사용하고 있지만 현재로서는 주석을 사용할 수 없습니다. 아래에 HBM, DAO 등의 사본을 첨부했습니다.

public class CharityTransferDAO extends HibernateDaoSupport implements ICharityTransfer { 

    public void delete(CharityTransfer charityTransfer) throws IMADataException {

     getSessionFactory() 
       .getCurrentSession()

Answer 1

는이 오류 모든 시간을 발생했습니다.

관계에 inverse = "true"를 넣으면 문제가 사라집니다!

<list name="charityTransferItemList" inverse="true" cascade="all-delete-orphan" lazy="false" > 
     <key column="TSF_NO" /> 
     <list-index column="TSF_SEQ_NO"/> 
     <one-to-many class="CharityTransferItem" /> 
    </list> 

는 기본적으로 반대하여 아이를 삭제 최대 절전 모드의 원인, 부모 없이는 존재할 수 없습니다 아이를 최대 절전 모드 말할 ​​것이다.

그렇다면 부모의 컬렉션에서 charityTransfer 객체도 제거해야합니다.

Answer 2

(참고 : 이는 두 명의 사용자가 잘못된 대답으로 제기했습니다.)

<list name="charityTransferItemList" cascade="all,delete-orphan" lazy="false"> 
     <key column="TSF_NO" not-null="true" /> 
     <list-index column="TSF_SEQ_NO"/> 
     <one-to-many class="CharityTransferItem" /> 
</list> 

Hibernate doc on collections에서 :

최대 절전 모드 문서는 not-null="true"로 키 열 표시 단지 수 있다고 나는 또한 당신의 캐스케이드 스타일에 오타가 있다고 생각

If the foreign key column of a association is declared NOT NULL, you must declare the mapping not-null="true" or use a bidirectional association with the collection mapping marked inverse="true". See the discussion of bidirectional associations later in this chapter for more information.

을 (all-delete-orphan이 있어야한다 all,delete-orphan).
