原因分析: A對象在級聯保存B對象時, B對象沒有生成id, 導致存在表中時無法生成B對象的外鍵.
解決: 1. 通過查詢方法,將B對象查詢出來, 然後再通過A對象的set方法存儲B對象即可. 在這裏A對象是order, B對象是persistArea和recArea
Area sendArea = order.getSendArea();
//遍歷限制區域對象,拿到限制區域對象裏的所有分區
Area persistArea = areaService.findByProvinceAndCityAndDistrict(sendArea.getProvince(),sendArea.getCity(),sendArea.getDistrict());
//收件人的區域
Area recArea = order.getRecArea();
Area persistRecArea = areaService.findByProvinceAndCityAndDistrict(recArea.getProvince(),recArea.getCity(),recArea.getDistrict());
//重新存儲區域信息
order.setSendArea(persistArea);
order.setRecArea(persistRecArea);
2. 可以通過設置B對象爲null 來解決,然後再set進入A對象解決; 在這裏A對象是model, B對象是order
if(order!=null&&(order.getId()==null||order.getId()==0)){
model.setOrder(null);
}
