取出数据库中的值并放在列表中

protected List getData() {
     List list = null;
  Transaction tx = null;
  try {
   session = HibernateUtil.currentSession();
   tx = session.beginTransaction();
   Query q = null;
    String hql = "from WqDcShujuVpnServiceInfo shuzuvpnservice where 1=1"

    q = session.createQuery(hql);
    q = setParameter(q);
   list = q.list();
   tx.commit();
  } catch (HibernateException e) {
   if (tx != null)
    tx.rollback();
   throw e;
  } finally {
   try {
    HibernateUtil.closeSession();
   } catch (HibernateException e1) {
