先贴代码

    public void hqlQuery(){
    Session session = (Session) HibernateSessionUtil.getSession();
    String hql = "from Order as o where o.status=:status and o.total_price=:price";
    System.out.println(hql);
    Query query = session.createQuery(hql);
   
       query.setString("status","火速处理");
       query.setDouble("price",30);
      
       List<Order> orders = query.list();
       System.out.println(orders.size());  //这里为0
       for(Order order : orders){
        System.out.println(order.getPhone());
       }
       session.close();
   }
