Hibernate集合与任何会话都没有关联 [英] Hibernate collection is not associated with any session

问题描述

我在这个问题上发现了几个关于SO的问题和答案，但它们似乎都涵盖了一个主要原因：在一个事务之外或另一个事务之内获取一个集合。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。

  @Service 
 @Transactional 
公共类IntegrationServiceImpl实现IntegrationService {
 @Override 
 public Integration getIntegrationByIdFetchBackendParameters（Long integrationId）{
 Integration integration = integrationDao.get（integrationId）; 
 //不是所有的集成都必须有后端。 
 if（integration.getBackend（）！= null）{
 Hibernate.initialize（integration.getBackend（）。getBackendParameters（））; 
} 
返回集成; 
} 
 ... 
  

但是，当涉及到Hibernate.initialize this分支在org.hibernate.collection.internal.AbstractPersistentCollection
被执行

  if（session == null）{
抛出新的HibernateException（集合不与任何会话关联）; 
} 
  

我不明白为什么 session 是 null 。有人会解释这一点并提出解决方案吗？

解决方案
我解决了这个问题，只是将 @Transactional 放在方法的顶部。
 
I have found several questions and answers with regard to this issue on SO, but they all seem to cover one major cause of the problem: fetching a collection outside of a transaction or within another transaction.  But in my case, I am fetching within the same transaction when fetching a parent object and collection. 
@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;
    }
...
But when it comes to Hibernate.initialize this branch in  org.hibernate.collection.internal.AbstractPersistentCollection
is executed 
if ( session == null ) {
                throw new HibernateException( "collection is not associated with any session" );
            }
I cant see why session is null. Would someone explain this and suggest a solution?
