在Controller层需要两个方法，一个就是获取店铺信息
getShopById
1 /** 2 * 根据店铺信息获取店铺 3 * @param request 4 * @return 5 */ 6 @RequestMapping(value="/getshopbyid", method=RequestMethod.GET) 7 @ResponseBody 8 private Map<String, Object> getShopById(HttpServletRequest request){ 9 Map<String, Object> modelMap = new HashMap<>(); 10 Long shopId = HttpServletRequestUtil.getLong( request, "shopId" ); 11 if(shopId > -1){//大于-1就证明前端传过来了 12 try{ 13 Shop shop = shopService.getShopByShopId( shopId ); 14 List<Area> areaList = areaService.getAreaList();//因为区域信息是可以更改的，所以需要获取 15 modelMap.put("shop", shop); 16 modelMap.put( "areaList", areaList ); 17 modelMap.put( "success", true ); 18 } catch(Exception e){ 19 modelMap.put("success", false); 20 modelMap.put("errMsg", e.toString()); 21 } 22 23 }else{ 24 modelMap.put("success", false); 25 modelMap.put( "errMsg", "empty shopId" ); 26 } 27 return modelMap; 28 }
更改店铺信息（和注册店铺相似）
1.先看传递过来的验证码
2.接受从前台传过来的shopStr的字符串
3.将shopStr转成Shop实体对象
4.前台传过来的文件流解析成CommonsMultipartFile里面去
5.最后将Shop对象和文件流使用Service层方法添加
1 @RequestMapping(value = "/modifyshop", method = RequestMethod.POST) 2 @ResponseBody 3 private Map<String, Object> modifyShop(HttpServletRequest request) { 4 Map<String, Object> modelMap = new HashMap<String, Object>(); 5 if (!CodeUtil.checkVerifyCode(request)) { 6 modelMap.put("success", false); 7 modelMap.put("error", "输入了错误的验证码"); 8 return modelMap; 9 } 10 // 1.接受并转化相应的参数，包括店铺信息以及图片信息 11 String shopStr = HttpServletRequestUtil.getString(request, "shopStr"); 12 ObjectMapper mapper = new ObjectMapper(); 13 Shop shop = null; 14 try { 15 shop = mapper.readValue(shopStr, Shop.class); 16 } catch (Exception e) { 17 modelMap.put("success", false); 18 modelMap.put("errMsg", e.getMessage()); 19 return modelMap; 20 } 21 CommonsMultipartFile shopImg = null; 22 CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver( 23 request.getSession().getServletContext()); 24 // 如果文件上传有值的话 25 if (commonsMultipartResolver.isMultipart(request)) { 26 MultipartHttpServletRequest multipartHttpServletRequest = (MultipartHttpServletRequest) request; 27 shopImg = (CommonsMultipartFile) multipartHttpServletRequest.getFile("shopImg"); 28 }//图片可上传可不上传的 非空判断可以去掉 29 // 2.修改店铺信息 30 if (shop != null && shop.getShopId() != null) {//确保shopId不为空 31 ShopExecution se; 32 try { 33 // 当文件为空时 直接传入空值 34 if (shopImg == null) { 35 se = shopService.modifyShop(shop, null, null); 36 } else { 37 se = shopService.modifyShop(shop, shopImg.getInputStream(), shopImg.getOriginalFilename()); 38 } 39 // se = shopService.modifyShop(shop, 40 // shopImg.getInputStream(),shopImg.getOriginalFilename()); 换成了上面这个if else 判断 41 if (se.getState() == ShopStateEnum.SUCCESS.getState()) {//CHECK->SUCCESS 42 modelMap.put("success", true); 43 } else { 44 modelMap.put("errMsg", se.getStateInfo()); 45 } 46 } catch (ShopOperationException e) { 47 modelMap.put("success", false); 48 modelMap.put("errMsg", e.getMessage()); 49 } catch (IOException e) { 50 modelMap.put("success", false); 51 modelMap.put("errMsg", e.getMessage()); 52 } 53 54 return modelMap; 55 } else { 56 modelMap.put("success", false); 57 modelMap.put("errMsg", "请输入店铺ID"); 58 return modelMap; 59 } 60 // 3.返回结果 61 }
顺便在注册方法中Session
通过Session获取登录后的user信息
PersonInfo owner = (PersonInfo) request.getSession().getAttribute("user");
shop.setOwner(owner);
获取user信息后设置user可操作的店铺列表
1 @SuppressWarnings("unchecked") 2 List<Shop> shopList = (List<Shop>) request.getSession().getAttribute("shopList"); 3 if (shopList == null || shopList.size() == 0) { 4 shopList = new ArrayList<Shop>(); 5 } 6 shopList.add(se.getShop()); 7 request.getSession().setAttribute("shopList", shopList);
