java - how - La colección de hibernación no está asociada con ninguna sesión.
set name to jframe (6)
He encontrado varias preguntas y respuestas con respecto a este problema en SO, pero todas parecen cubrir una causa importante del problema: obtener una colección fuera de una transacción o dentro de otra transacción. Pero en mi caso, estoy obteniendo dentro de la misma transacción cuando obtengo un objeto y colección principal.
@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;
}
...
Pero cuando se trata de Hibernate, inicialice esta rama en org.hibernate.collection.internal.AbstractPersistentCollection se ejecuta
if ( session == null ) {
throw new HibernateException( "collection is not associated with any session" );
}
No puedo ver por qué la session es null . ¿Alguien explicaría esto y sugeriría una solución?
EDIT 1 - Rastreo de pila completa

Como lo ha señalado @Zmicier Zaleznicenka, este mensaje de excepción puede no tener nada que ver con la sesión. También hemos encontrado este problema, pero la causa raíz fue que la configuración de la clave principal de la entidad definida en el archivo de asignación era incorrecta. Por ejemplo, en el siguiente código, la columna de la base de datos "Foo_SK" no es el identificador único de la tabla.
Id(x => x.Id, "Foo_SK").GeneratedBy.Assigned();
En nuestro caso, no tenemos control sobre el esquema de la base de datos. Por lo tanto, solucionamos el problema mediante el uso de asignación de clave compuesta.
Por favor, consulte la otra publicación para el mismo problema.
Para evitar una LazyLoadingException en mi aplicación, uso un método auxiliar que primero fusiona la entidad con la sesión y luego inicializa las colecciones solicitadas. Recientemente resultó que, a veces, todavía tiene el problema de "la colección no está asociada con ninguna sesión" a pesar de que la sesión parece estar abierta y se ve bien en general. Es difícil para mí decir cuál es la causa de tal comportamiento, pero aún así encontré un remedio para evitarlo. Intente actualizar el estado de la entidad antes de recuperar la colección perezosa utilizando session.refresh(entity) . Esto hará que Hibernate vuelva a cargar su entidad desde la base de datos. Después de hacer esto, su sesión actual le permitirá cargar sus colecciones sin problemas con Hibernate.initialize() .
Parece que lo llamas en tu método init de AbstractIntegrationManagedBean .
Tienes que asegurarte de que la hibernación se configure correctamente antes de ese punto.
Lo más probable es que su configuración no refleje eso y usted asuma que la hibernación ya está allí, aunque no hay garantía de ello.
Consulte esta pregunta para obtener más detalles: ¿Cómo controlar el orden de invocación del método init de bean en Spring?
Yo también tuve este problema, sin embargo, el problema para mí era que no estaba configurando la administración transaccional en mi archivo de configuración, así que:
agregue @EnableTransactionManagement al archivo de configuración de Java o agregue <tx:annotation-driven/> al archivo de configuración xml
@Transactional este problema simplemente poniendo @Transactional en la parte superior del método. Y también obtener la clase por su id como este:
