QueryAllAction中

  List<Student> studentlist=new ArrayList<Student>();

  Session session=null;

  try{

   session=HibernateUtil.getSession();

   String hql="from Student stu";

   Query q=session.createQuery(hql);

   studentlist=q.list();

   request.setAttribute("studentlist",studentlist);

//此句忘了没写，jsp页面里面就是查不到，悲催


   for(java.util.Iterator<Student> iterator= studentlist.iterator();iterator.hasNext();){

    Student student=(Student)iterator.next();

    System.out.println("id: "+student.getId()+" "+"姓名: "+student.getName()+" "+"性别: "+student.getSex()+" "+"地址: "+student.getAddress());

   }

  

    }catch(Exception e){

     e.printStackTrace();

    }finally{

     HibernateUtil.closeSession();

    }

  return "queryAll";

 }
