添加数据的时候，会报错：

我写的时候表单数据是从相应外键表中获取的值，再通过选择的值查询，得到一个bean，如下
int provinceID = Integer.parseInt(getRequest().getParameter("province").toString());
IshequProvinceList province = provinceBiz.findByProvinceId(provinceID);
Shoop shop = new Shoop();
shop.setIschoolIshequProvinceList(province);
最后执行增加
int flag = shoopBiz.addShoop(shop);
我已经检查很多次，shop表的数据除了主键是自增的，没设置有值，其他的都设置了值。
求解决。
