下面是我整合ssh的时候启动tomcat的时候报的异常

BaseDaoImpl.java
@Repository
public class BaseDaoImpl implements BaseDao {
@Autowired
private SessionFactory sessionFactory;
public List<BaseTO> queryAll(String hql) throws DaoException {

return sessionFactory.getCurrentSession().createQuery(hql).list();
}

}

AppUserDaoImpl.java
@Repository
public class AppUserDaoImpl extends BaseDaoImpl implements AppUserDao {
}
请问是怎么回事？

[解决办法]
sessionFactory.getCurrentSession().createQuery(hql).list();
改为
sessionFactory.openSession().createQuery(hql).list();
