1. Controller要修改的有：

将 goodsForm.setType("粮食");

    model.addAttribute("goodsForm",goodsForm);

改为 List<GoodsForm> commodityType = goodsService.getType(goodsForm);

        goodsForm.setCommodityTypeId(commodityType.get(0).getCommodityTypeId());//选择第一项的Id

        model.addAttribute("goodsForm", goodsForm);

        model.addAttribute("commodityType", commodityType));

其中 List<GoodsForm> commodityType = goodsService.getType(goodsForm);

        model.addAttribute("commodityType",commodityType);

等价于 model.addAttribute("commodityType",goodsService.getType(goodsForm);

涉及要修改这几句代码的地方如下：

（1）AlipayController.java中value = "alipaySubmit" value = "replayAlipaySubmit" value = "guestAlipaySubmit"方法

其中value = "guestAlipaySubmit"方法中，先添加goodsForm.setCommodityId(alipayForm.getCommodityId());而且原本有的model.addAttribute("goodsForm", goodsForm);与新添加的model.addAttribute("goodsForm", goodsService.searchGoods(goodsForm));重复，应去掉一句。

（2）CartController.java中value = "initCart" value = "addCart" value = "delCart" value = "alipayConfirm" value = "replayAlipay"方法。其中value = "addCart"方法还得先获取goodsForm.setCommodityId(cartForm.getCommodityId());

（3）GoodsController.java涉及得比较多，就不一一细说，代码如下

@RequestMapping(value = "initGoods", method = RequestMethod.GET)    public String initGoods(Model model, HttpSession session, GoodsForm goodsForm, Device device) throws UnsupportedEncodingException {    	log.info("商品列表初始化");    	model.addAttribute("list", goodsService.getTypeList(goodsForm));    	model.addAttribute("commodityType", goodsService.getType(goodsForm));    	model.addAttribute("goodsForm", goodsForm);    	UVO uvo = (UVO)session.getAttribute("UVO");    	if (uvo == null) {    		uvo = new UVO();    		session.setAttribute("UVO", uvo);    	}    	CartForm cartForm = new CartForm();    	cartForm.setGuestId(uvo.getGuestId());    	model.addAttribute("cartList", cartService.searchCartList(cartForm));    	if(device.isNormal()) {    		return "shop/index";    	} else {    		return "mobile/index";    	}    }        @RequestMapping(value = "initGoodsDetail", method = RequestMethod.GET)    public String initGoodsDetail(Model model, HttpSession session, GoodsForm goodsForm, Device device) {    	log.info("商品明细初始化");    	model.addAttribute("commodityType", goodsService.getType(goodsForm));    	UVO uvo = (UVO)session.getAttribute("UVO");    	if (uvo == null) {    		uvo = new UVO();    		session.setAttribute("UVO", uvo);    	}    	CartForm cartForm = new CartForm();    	cartForm.setGuestId(uvo.getGuestId());    	model.addAttribute("cartList", cartService.searchCartList(cartForm));    	model.addAttribute("goodsForm", goodsService.searchGoods(goodsForm));    	if(device.isNormal()) {    		return "shop/goods/goodsDetail";    	} else {    		return "mobile/goods/goodsDetail";    	}    }        @RequestMapping(value = "selectGoods", method = RequestMethod.POST)    public String  selectGoods(Model model,HttpSession session,GoodsForm goodsForm,Device device){    	log.info("检索相关商品");    	model.addAttribute("commodityType", goodsService.getType(goodsForm));    	List
    
      list=goodsService.searchGoodsListrelative(goodsForm);    	model.addAttribute("list",list);    	UVO uvo = (UVO)session.getAttribute("UVO");    	if (uvo == null) {    		uvo = new UVO();    		session.setAttribute("UVO", uvo);    	}    	CartForm cartForm = new CartForm();    	cartForm.setGuestId(uvo.getGuestId());    	model.addAttribute("cartList", cartService.searchCartList(cartForm));    	if(device.isNormal()) {    		return "shop/index";    	} else {    		return "mobile/index";    	}    }}
    

（4）GuestController.java中value = "/" value = "initGuestLogin" value = "guestLogin" value = "initGuestRegister" value = "addGuest" value = "initEditGuest" value = "editGuest"方法

（5）SpecialController.java中value = "initSpecialAlipayComfirm" value = "specialAlipaySubmit" 方法

2. Form要添加内容：

private String commodityTypeId;

private String commodityTypeName;

3. SqlMap要改的有：

GoodsSqlMap.xml里的id="selectGoods"里的commodity.type as type改为commodity.type as commodityTypeId

4. topBar.html改为：

th:each="goodsInfo,status:${commodityType}"表示循环commodityType中的全部数据
