我有以下问题。在我的检票口应用程序中,我想使用 @Transactional 注释。我所有的 DAO 都加载了 @Component 注释;
@Component
@Transactional(propagation = Propagation.SUPPORTS)
public class AccountHibernateDataAccessHelper implements
AccountDataAccessHelper
{
@Override
@Transactional(propagation = Propagation.REQUIRED)
public void saveOrUpdate(T dataObject)
{
try
{
Session session = getSessionProvider().getSession();
session.saveOrUpdate(dataObject);
}
catch (HibernateException e)
{
String message = "Failed to batch save or update " + dataObject;
log.error(message, e);
}
}
@SuppressWarnings("unchecked")
public <R extends T> List<R> list(Class<R> class1)
{
Asserts.assertNotNull("class1", class1);
try
{
return createCriteria(class1).setCacheable(true)
.setCacheRegion(getQueryCacheRegion()).list();
} catch (HibernateException e)
{
String message = "Failed to get a list of" + class1;
log.error(message, e);
throw new DataAccessException(message, e);
} catch (RuntimeException e)
{
log.error(e.toString(), e);
throw new DataAccessException(e);
}
}
}
我的 AccountDataAccesshelper 实现了以下接口
public interface DataAccessHelper<T>
{
public Serializable save(T dataObject);
public void saveOrUpdate(T dataObject);
public void update(T dataObject);
public void delete(T dataObject);
public void evict(T dataObject);
}
接下来是我的 appllicationcontext.xml 设置。
<context:component-scan base-package="nl.response.webapp" />
<context:annotation-config />

会话提供者提供如下会话
public Session getSession()
{
getSessionFactory().openSession();
}
当我使用上述会话方法时,没有提交任何内容,并且由于连接没有正确关闭,所以我收到一个错误。
当我使用 getSessionFactory.getCurrentSession() 时,出现以下错误
如果没有活动事务,createCriteria 无效
我错过了什么?我已经尝试让这个工作好几天了,我没有选择:S
