原因分析:  A对象在级联保存B对象时, B对象没有生成id, 导致存在表中时无法生成B对象的外键.

解决: 1. 通过查询方法,将B对象查询出来, 然后再通过A对象的set方法存储B对象即可. 在这里A对象是order, B对象是persistArea和recArea

Area sendArea = order.getSendArea();
        //遍历限制区域对象,拿到限制区域对象里的所有分区
        Area persistArea =     areaService.findByProvinceAndCityAndDistrict(sendArea.getProvince(),sendArea.getCity(),sendArea.getDistrict());
        
        //收件人的区域
        Area recArea = order.getRecArea();
        Area persistRecArea =     areaService.findByProvinceAndCityAndDistrict(recArea.getProvince(),recArea.getCity(),recArea.getDistrict());
        //重新存储区域信息
        order.setSendArea(persistArea);
        order.setRecArea(persistRecArea);

2. 可以通过设置B对象为null 来解决,然后再set进入A对象解决;   在这里A对象是model, B对象是order

    if(order!=null&&(order.getId()==null||order.getId()==0)){
            model.setOrder(null);
        }
