添加數據的時候，會報錯：

我寫的時候表單數據是從相應外鍵表中獲取的值，再通過選擇的值查詢，得到一個bean，如下
int provinceID = Integer.parseInt(getRequest().getParameter("province").toString());
IshequProvinceList province = provinceBiz.findByProvinceId(provinceID);
Shoop shop = new Shoop();
shop.setIschoolIshequProvinceList(province);
最後執行增加
int flag = shoopBiz.addShoop(shop);
我已經檢查很多次，shop表的數據除了主鍵是自增的，沒設置有值，其他的都設置了值。
求解決。
ischool_ishequ_city_list (cityid) 仔細看看數據庫
