detail是ProfitPage物件；

ProfitPage物件是通過JsonString轉換過來的

Gson gson = new GsonBuilder().enableComplexMapKeySerialization().create();
String jsonString = gson.toJson(detail.getDetail());
List<VbillCardProfitBean> vbillQrcodeProfitBeans = gson.fromJson(jsonString,List.class);

在這裡並沒有將list集合轉換為List<vbillQrcodeProfitBeans>,還需要將遍歷一遍
if(vbillQrcodeProfitBeans!=null&&vbillQrcodeProfitBeans.size()>0){
    for (Object vbillCardProfitBeanLinked:
            vbillQrcodeProfitBeans ) {
        String vbillCardProfitBeanStr = gson.toJson(vbillCardProfitBeanLinked);
        VbillCardProfitBean vbillCardProfitBean = gson.fromJson(vbillCardProfitBeanStr,VbillCardProfitBean.class);
     
        }

    }
}
