[SPRING] Hibernate 콜렉션은 어떤 세션과도 연관되지 않는다.
SPRINGHibernate 콜렉션은 어떤 세션과도 연관되지 않는다.
나는이 문제와 관련하여 몇 가지 질문과 답변을 찾았지만 문제의 주요 원인 중 하나를 다루는 것 같습니다 : 트랜잭션 외부 또는 다른 트랜잭션 내에서의 콜렉션 가져 오기. 하지만 제 경우에는 부모 객체와 컬렉션을 가져올 때 같은 트랜잭션 내에서 가져옵니다.
@Service
@Transactional
public class IntegrationServiceImpl implements IntegrationService {
@Override
public Integration getIntegrationByIdFetchBackendParameters(Long integrationId) {
Integration integration = integrationDao.get(integrationId);
//not all integrations have to have backend.
if (integration.getBackend() != null) {
Hibernate.initialize(integration.getBackend().getBackendParameters());
}
return integration;
}
...
그러나 Hibernate에 관해서는 org.hibernate.collection.internal.AbstractPersistentCollection에서이 브랜치를 초기화한다. 실행 됨
if ( session == null ) {
throw new HibernateException( "collection is not associated with any session" );
}
세션이 null 인 이유를 알 수 없습니다. 누군가가 이것을 설명하고 해결책을 제안 할 것입니까?

==============================
2.응용 프로그램에서 LazyLoadingException을 방지하기 위해 먼저 엔티티를 세션에 다시 병합 한 다음 요청 된 콜렉션을 초기화하는 헬퍼 메소드를 사용합니다. 최근에, 세션이 열려있는 것처럼 보이고 전반적으로 잘 보이지만 "컬렉션이 모든 세션과 관련이 없습니다."라는 쟁점이있는 경우가 있습니다. 그러한 행동의 원인이 무엇인지 말할 수는 없지만 여전히 그것에 대한 구제책을 찾았습니다. session.refresh (entity)를 사용하여 Lazy Collection을 가져 오기 전에 엔티티 상태를 새로 고침하십시오. 이것은 Hibernate로 하여금 당신의 엔티티를 DB로부터 다시로드하게 할 것이다. 이렇게하면, 현재 세션은 Hibernate.initialize ()를 사용하여 콜렉션들을 부드럽게로드 할 수있게 해줄 것이다.

3.@ Zmicier Zaleznicenka가 지적했듯이이 예외 메시지는 Session과 아무 관련이 없습니다. 이 문제가 발생했으나 매핑 파일에 정의 된 엔터티 기본 키 설정의 근본 원인이 잘못되었습니다. 예를 들어 다음 코드에서 데이터베이스 열 "Foo_SK"는 테이블의 고유 식별자가 아닙니다.

Id(x => x.Id, "Foo_SK").GeneratedBy.Assigned();우리의 경우에는 데이터베이스 스키마를 제어 할 수 없습니다. 따라서 복합 키 매핑을 사용하여 문제를 해결했습니다.

6.AbstractIntegrationManagedBean의 init 메소드에서 이것을 호출하는 것처럼 보입니다.
AbstractIntegrationManagedBean의 init 메소드에서 이것을 호출하는 것처럼 보입니다.
그 시점 이전에 최대 절전 모드가 올바르게 설정되었는지 확인해야합니다.
가장 가능성있는 구성은이를 반영하지 않으며 최대 절전 모드가 이미 존재한다고 가정하지만 보장 할 수는 없습니다.
