service层

@Overridepublic User checkUser(User user){User user1 = new User();List list = userdao.checkUser(user);if(list.size() != 0){user1 = (User)list.get(0);return user1;}return null;}

Dao层

@Overridepublic List checkUser(User user) {Session session = sessionfactory.openSession();Query query = session.createQuery("from User where username='"+user.getUsername()+"' and password ='"+user.getPassword()+"' and role = '"+user.getRole()+"'");List list = query.list();return list;}
