老师你好，在同一个事务下，我插入店铺之后，再进行更新店铺，插入成功然后更新失败，最后定位问题到在这个事务下查询不到之前插入的店铺，我用的数据库是Oracle，查询和更新方法都测过没问题，老师帮忙看看。
`@Override
@Transactional(propagation=Propagation.REQUIRED)
public ShopExcution addShop(Shop shop, File shopImg) {
//判断传入的店铺信息是否为空
if (shop == null) {
return new ShopExcution(ShopStateEnum.NULL_SHOP);
}

	try {
		//给shop赋值
		shop.setEnableStatus(0);  //审核中
		shop.setCreateTime(new Date());
		shop.setLastEditTime(new Date());
		int effectedNum = shopDao.insertShop(shop);
		if (effectedNum <= 0) {
			throw new ShopOperationException("店铺创建失败");
		}else {
			//店铺创建成功且当有图片传入时
			if (shopImg != null) {
				//存储图片
				try {
					addShopImg(shop,shopImg);
				} catch (Exception e) {
					throw new ShopOperationException("addShopImg error:" + e.getMessage());
				}
				Long aString = shopDao.selectShopById(shop.getShopId());
				//更新店铺的图片的地址
				effectedNum = shopDao.updateShop(shop);
				if (effectedNum <= 0) {
					throw new ShopOperationException("更新图片地址失败");
				}

			}
		}
		
	} catch (Exception e) {
		throw new ShopOperationException("add shop error" + e.getMessage());
	}
	
	return new ShopExcution(ShopStateEnum.CHECK, shop);
}
