Spring boot 2.2.9 Hibernate 错误：org.hibernate.HibernateException：无法获取当前线程的事务同步会话

Question

我已经在 StackOverflow 上搜索并查看了所有现有答案，以了解我看到的错误。我尝试应用所有建议，但仍然无法摆脱这个可怕的错误

Caused by: org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread
        at org.springframework.orm.hibernate5.SpringSessionContext.currentSession(SpringSessionContext.java:143)
        at org.hibernate.internal.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:475)
        at com.myComp.core.persistence.HibernateUtils.find(HibernateUtils.java:82)

我正在使用 Spring boot 2.2.9 和 spring data jpa。我正在使用 SessionFactory 使用straight hibernate 实现来获取我的会话。我已经在我的 Service 上声明了 @Transactional 注释并从 Dao 类内部调用 sessionFactory.getCurrentSession() ，这就是我遇到此错误的地方。

这是我的 Spring xml 配置（我还没有使用 Java Config）

我的类路径上有 CGLIB，Spring aspectj。我正在使用 java 1.8 运行它 我已经尝试使用 mode = proxy 和 aspectj 进行事务注释配置。我什至尝试过 proxy-target-class= true 和 false。我所有的尝试都失败了。 我在我的 Spring 容器之外提取 Spring 托管 bean“masterAssetApi”（服务类 LocalAssetApiImpl 的实例，其中贴有 @Transaction），并在我的主应用程序中调用我的服务方法。这不是像常规 Spring 应用程序那样的 Spring 应用程序。 这是一个示例代码

AssetApiImplInterface master = springContext.getBean("masterAssetApi");
master.getUser("20"); 
//getUser service method has read-only=true with @Transactional annotation

这里是 HibernateUtils 代码

   public <T> java.util.List<T>  find(final SessionFactory sessionFactory, final String queryString, final Map<String, Object> args, Class<T> cls, final String extendedErrorMessage)
      throws PersistenceException
   {
      try
      {
         try
         {
            Session session = sessionFactory.getCurrentSession();
            Query<T> qry = session.createQuery(queryString);
            for(Map.Entry<String, Object> entry: args.entrySet()) {
               qry.setParameter(entry.getKey(), entry.getValue());
            }
            List<T> ret = qry.list();
            return ret;
         }
         catch (final HibernateException exception) {
            throw SessionFactoryUtils.convertHibernateAccessException(exception);
         }
      }
      catch (final BadSqlGrammarException bsg)
      {
         tracer.exception(bsg);
         throw new PersistenceException(PersistenceException.SESSIONFAILURE, extendedErrorMessage, bsg);
      }
      catch (final DataAccessException dae)
      {
         tracer.exception(dae);
         throw new PersistenceException(PersistenceException.SESSIONFAILURE, extendedErrorMessage, dae);
      }
      catch (final Exception ex)
      {
         tracer.exception(ex);
         try
         {
            Thread.sleep(exceptionHiatus);
         }
         catch (final InterruptedException e)
         {
            tracer.debug("Slumber interrupted " + e.getMessage());
         }
         throw new PersistenceException(PersistenceException.SESSIONFAILURE, extendedErrorMessage, ex);
      }
   }

这里是调用堆栈跟踪。

@Transactional 注解围绕 LocalAssetApiImpl.getSubGrid(..)

注意：我使用 BeanFactory IOC 容器来加载我的 Spring Xml 而不是 ApplicationContext。您认为这可能是问题所在吗？

任何帮助将不胜感激。 谢谢

我终于解决了这个问题，我遇到了。使用 BeanFactory 是个问题。 当我切换到 ApplicationContext IOC 后，我的问题就消失了。
