我在使用Hibernate4时有一个spring应用程序，它与StageDaoImpl中的sessionFactory.openSession（）一起使用：
@Repository(value = "stageDao")
public class StageDaoImpl implements StageDao {
@Autowired
private SessionFactory sessionFactory;
@Override
public Integer editStage(Stage stage) {
Session session = sessionFactory.openSession();
Integer ban = 1;
try {
session.beginTransaction();
session.update(stage);
session.getTransaction().commit();
} catch (HibernateException e) {
ban = -1;
} catch (Exception e) {
ban = -2;
} finally {
session.close();
}
return ban;
}
我尝试将editStage更改为@Transactional注释，但我不知道如何配置事务，它始终是相同的结果
@Repository(value = "stageDao")
public class StageDaoImpl implements StageDao {
@Autowired
private SessionFactory sessionFactory;
@Override
@Transactional
public Integer editStage(Stage stage) {
Session session = sessionFactory.getCurrentSession();
Integer ban = 1;
try {
session.update(stage);
} catch (HibernateException e) {
ban = -1;
} catch (Exception e) {
ban = -2;
}
return ban;
}
错误StackTrace：
org.hibernate.HibernateException: No Session found for current thread
