这个是登陆源码public boolean loginObject(User user) throws HibernateException{ System.out.println("6666666666666"); //String hql=("from User u where?u.username=? and u.password=?",user.getUsername(),user.getPassword()); //System.out.println("from User u where?u.username=? and u.password=?",user.getUsername(),user.getPassword()); List<User> userlist=getHibernateTemplate().find("from User u where?u.username=? and u.password=?",user.getUsername(),user.getPassword()); if(userlist.size()>0) return true; else return false; }这个是报的错
