3.查询订单详细信息

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
