        在客户的页面上查询我的订单,点击确认收货的时候 修改订单的状态
    1.点击 修改状态
        /store/adminOrder?method=updateState&oid=??state=??
    2.在updatestate方法中,
        接受参数 oid  state
        调用service修改状态
        重定向 查询所有订单已支付的订单列表上

 /store/src/com/louis/web/servlet/AdminOrderServlet.java

/*
     * 修改订单状态
     */
    public  String updateState(HttpServletRequest request, HttpServletResponse response) throws Exception {
        //1.接受 oid state
        String oid = request.getParameter("oid");
        String state = request.getParameter("state");
        
        //2.调用service 
        OrderService os=(OrderService) BeanFactory.getBean("OrderService");
        Order order = os.getById(oid);        
        order.setState(2);
        
        os.update(order);
        
        //3.页面重定向
        response.sendRedirect(request.getContextPath()+"/adminOrder?method=findAllByState&state=1");
        return null;
    }
