我已经发现了几个问题和答案对于这个问题上，所以任何会话相关的，但他们似乎都掩盖了问题的一个重要原因：获取集合的事务之外或其他事务中。但在我的情况下，我在获取父对象和集合时在同一个事务中进行读取。休眠收集未与
@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;
}
...
但说到在org.hibernate.collection.internal.AbstractPersistentCollection 到这个状态，Hibernate.initialize分支执行
if (session == null) {
throw new HibernateException("collection is not associated with any session");
}
我不能明白为什么session是null。有人会解释这一点并提出解决方案吗？

请加满堆栈跟踪... –
我已经添加了完整的堆栈跟踪。请参阅编辑。 – DominikM
stacktrace表示没有事务正在进行。基本上你的'@ Transactional'没有做任何事情。发布您的配置（包括web.xml） –
