为什么没有回滚事务呢?

Question

@Service
public class ShopServiceImpl implements ShopService {
	@Autowired
	private ShopDao shopDao;

	@Override
	@Transactional
	public ShopExecution addShop(Shop shop, File shopImg) {
		if (shop == null) {
			return new ShopExecution(ShopStateEnum.NULL_SHOP);
		}
		try {	
			shop.setEnableStatus(0);
			shop.setCreateTime(new Date());
			shop.setLastEditTime(new Date());
			int effectedNum = shopDao.insertShop(shop);
			if (effectedNum <= 0) {
				throw new RuntimeException("店铺创建失败");
			} else {
				if (shopImg != null) {
					try {
						// 存储图片
						addShopImg(shop, shopImg);
					} catch (Exception e) {
						throw new ShopOperationException("addShopImg error:" + e.getMessage());
					}
					// 更新店铺图片地址
					effectedNum = shopDao.updateShop(shop);
					if (effectedNum <= 0) {
						throw new ShopOperationException("更新图片地址失败");
					}
				}
			}
		} catch (Exception e) {
			throw new ShopOperationException("addShop error:" + e.getMessage());
		}
		return new ShopExecution(ShopStateEnum.CHECK, shop);
	}

	private void addShopImg(Shop shop, File shopImg) {
		// 获取shop图片目录的相对自路径
		String dest = PathUtil.getShopImagePath(shop.getShopId());
		String shopImgAddr = ImageUtil.generateThumbnail(shopImg, dest);
		shop.setShopImg(shopImgAddr);
	}

}

public class ShopOperationException extends RuntimeException {

/**

* 

*/

private static final long serialVersionUID = 8385422554610647351L;

public ShopOperationException(String msg) {

super(msg);

}

}

同学这个问题有点宽泛呢，只要完成事务前能够抛出runtimeexception就会回滚 但是物理图片保存的话是没办法回滚的 只能回滚数据库操作 同学可以用程序处理删库
