Hibernate 검색 문제 - 프록시를 초기화 할 수 없음 - no Session

최대 절전 모드를 사용하여 새 레코드를 추가 할 때 다음 예외가 있습니다. 나는 또한 인덱스를 만들기 위해 Hibernate 검색을 사용하고있다.Hibernate 검색 문제 - 프록시를 초기화 할 수 없음 - no Session

이것은 제 예외입니다.

이 오류는 느리게로드되는 속성이나 컬렉션에 액세스하려고하지만 최대 절전 모드 세션이 종료되었음을 의미합니다. Hibernate에서의 Lazy 로딩은 코드에서 프라퍼티/콜렉션에 접근 할 때까지 객체가 데이터베이스 쿼리를 통해 채워지지 않는다는 것을 의미한다. Hibernate는 처음에 객체를 사용할 때만 데이터베이스에 접근 할 동적 프록시 객체를 생성함으로써이를 수행한다. 이 작업을하기 위해서는, 당신의 객체는 그것의 생명주기 전체에 열려있는 Hibernate 세션에 붙어 있어야한다. 세션 관리 방법을 확인하십시오. 세션이 다른 곳에서 닫혀있는 경우 새 세션에 개체를 다시 연결해야 할 수 있습니다.

목적

는 현재 스레드에 결합 절전 세션으로 분리 된 도메인 예를 첨부 장착

예

데프 B= Book.get (1)
b.title = "어쩌구"
b.save (높이 : TRUE)
b.discard()

...
경우 (! b.isAttached()) {
b.attach()
}

설명

Grails는 관리 하이버 네이트를 사용 지속성 세션의 각 영구 객체. 요청 당 새 세션이 만들어지고 요청이 끝나면 닫힙니다. 객체가 세션에서 읽어지고 HttpSession과 같은 웹 범위에 배치되면 지속 세션이 닫혀 있기 때문에 분리 된 것으로 간주됩니다. attach() 메서드를 사용하여 기존 영구 인스턴스를 현재 요청의 지속성 세션에 다시 연결할 수 있습니다.

달리 할 말하지 않는 한 .... 3.0 이상이 느리게 컬렉션을로드 또한

최대 절전 모드가, 그것을 관리 할 최대 절전 모드, 달리 할 말하지 않는 한 귀하의 경우에 실행하는 동안 자신의 세션있어, 웹 앱 요청 ... 새로운 세션이 닫히고 열립니다. 따라서 부모를 검색하는 세션은 하위를 검색하도록 요청 된 세션과 같지 않을 수 있습니다.

요청에 OpenSessionInView 패턴을 적용하여 단일 세션을 유지 (재사용) 할 수 있습니다. 패턴을 적용하는 방법은 여러 가지가 있습니다 : 필터 (Spring의 OpenSessionInViewFilter), 인터셉터 (Spring의 OpenSessionInViewInterceptor), 웹 플로우 수신기 (Spring의 HibernateFlowExecutionListener)로 사용하거나, 전체를 시작하는 코드의 지점에서 직접 적용하십시오 음식물.

다른 접근 방법 : 게으른 로딩을 해제 , 적극적으로 객체 그래프로드 (!)들 Hibernate.initialize (컬렉션)
