jQuery需要引导Bootstrap JS文件：

更改此顺序：

    public void test() {

            Session session = HibernateUtil.currentSession();
            session.beginTransaction();

            Vehicle  vehicle= (Vehicle) session.get(Vehicle.class, 2);

            System.out.println(vehicle.getVehicleName());

            session.getTransaction().commit();
            session.close();
            System.out.println(vehicle.getVehicleName()); //No exception here
            System.out.println(vehicle.getUser().getUserName()); 
// Exception here change the loading to EAGER or put this line of code within the session above. Put it before session.close() or  before session.getTransaction().commit();
        }

这个脚本的订单：

<script type="text/javascript" src="bootstrap/js/bootstrap.min.js"></script>

<script type="text/javascript" src="jquery/jquery-2.1.4.js"></script>

bootstrap navbar toggle not collapsing
