Как установить значение списка массивов в одном объекте

Question

 Map<String, Object> productById = restTemplateUtil.getProductsByIds(accountId, clientId, client_type, accessToken, product_id);
           System.out.println(productById.get("data"));
           List<Map<String,Object> >productList = (List<Map<String, Object>>) productById.get("data");           System.out.println("");
           for(Map<String, Object> cartProduct : productList) {
               product_id = (String) cartProduct.get("product_id");
               String name = (String) cartProduct.get("name");
               String familyName = (String) cartProduct.get("familyName");
               String   imageUrl = (String) cartProduct.get("imageUrl");
               int  units = (int) cartProduct.get("units");
                double  unitRate = (double) cartProduct.get("unitRate");
               String category = (String) cartProduct.get("category");
               double unitDiscountPercent = (double) cartProduct.get("unitDiscountPercent");
               int unitGm = (int) cartProduct.get("unitGm");
               orders.setProductList(Arrays.asList( product_id, name, familyName, imageUrl,units,unitRate,category,unitDiscountPercent,unitGm));                                                        In this code my  Array is insert in database is like that

0: null 1: "Product A" 2: null 3: "image_url" 4: 0 5: 50 6: null 7: 5 8: 250

Я хочу, чтобы это было как 0: object product_id: "5ea0326ab89efb2804690a89" name: "Prodcut A" ImageUrl: "Imageurl"
