shop--6.店铺注册--controller层实现

1.接收并转化相应的参数，包括店铺信息和图片信息

2.注册店铺

3.返回结果

//注册店铺
    @RequestMapping(value="/registershop", method= RequestMethod.POST )
    @ResponseBody
    public Map<String, Object> registerShop(HttpServletRequest request){
        Map<String, Object> modelMap = new HashMap<>();
        //1.接收并转化相应的参数，包括店铺信息和图片信息
        String shopStr = HttpServletRequestUtil.getString( request, "shopStr" );
        ObjectMapper mapper = new ObjectMapper(); // create once, reuse
        Shop shop = null;
        try {
            shop = mapper.readValue(shopStr, Shop.class);
        } catch (IOException e) {
            modelMap.put("success", false);
            modelMap.put("errMsg", e.getMessage());
            return modelMap;
        }
        CommonsMultipartFile shopImg = null;
        //在本次会话的上下文获取上传的文件
        CommonsMultipartResolver commonsMultipartResolver =
                new CommonsMultipartResolver(request.getSession().getServletContext());
        //如果文件上传的有值
        if(commonsMultipartResolver.isMultipart( request )){
            MultipartHttpServletRequest multipartHttpServletRequest = (MultipartHttpServletRequest)request;
            shopImg = (CommonsMultipartFile)multipartHttpServletRequest.getFile("shopImg");
        } else{
            modelMap.put( "success", false );
            modelMap.put("errMsg", "上传图片不能为空");
            return modelMap;
        }
        //2.注册店铺
        if(shop != null && shopImg != null){
            PersonInfo user = (PersonInfo) request.getSession().getAttribute("user");
            shop.setOwner( user );
            ShopExecution shopExecution = shopService.addShop(shop, shopImg);
            if(shopExecution.getState() == ShopStateEnum.CHECK.getState()){
                modelMap.put( "success", true );

            }else{
                modelMap.put( "success", false );
                modelMap.put( "errMsg",  shopExecution.getStateInfo());
            }
        }else{
            modelMap.put("success", false);
            modelMap.put("errMsg", "请输入店铺信息");
        }
        //3.返回结果
        return modelMap;
    }
