OrderServlet

public String load(HttpServletRequest req, HttpServletResponse resp)
  throws ServletException, IOException {
 String oid = req.getParameter("oid");
 Order order = orderService.load(oid);
 req.setAttribute("order", order);
 String btn = req.getParameter("btn");//btn说明了用户点击哪个超链接来访问本方法的
 req.setAttribute("btn", btn);
 return "/jsps/order/desc.jsp";
}

desc.jsp

<div class="divOrder">
