{
SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
Session session = sessionFactory.getCurrentSession();
Transaction transaction = session.beginTransaction();
try {
String hql = "from Magicmarket";
Query query = session.createQuery(hql);
query.setFirstResult(firstNmu);
query.setMaxResults(maxNum);
List list = query.list();
transaction.commit();
return list;
} catch (Exception exception) {
exception.printStackTrace();
if (transaction != null)
transaction.rollback();
}
return null;
}
上面的方法中，最后一行代码return null;有什么用啊，是不是多余的。谁知道的解答下，不甚感激!
