没有数据插入和异常信息的输出

Question

如图所示，我的junit测试是绿色的，但是我检查数据库里面，并没有插入新的test1那些数据，控制台也没有老师视频里面的东西输出。不知道我是哪里出了问题，请老师指教。

package com.imooc.o2o.service.impl;

import java.io.File;
import java.util.Date;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.imooc.o2o.dao.ShopDao;
import com.imooc.o2o.dto.ImageHolder;
import com.imooc.o2o.dto.ShopExecution;
import com.imooc.o2o.entity.Shop;
import com.imooc.o2o.enums.ShopStateEnum;
import com.imooc.o2o.exceptions.ShopOperationException;
import com.imooc.o2o.service.ShopService;
import com.imooc.o2o.util.ImageUtil;
//import com.imooc.o2o.util.PageCalculator;
import com.imooc.o2o.util.PathUtil;

@Service
public class ShopServiceImpl implements ShopService {
	@Autowired
	private ShopDao shopDao;
	
	@Override
	@Transactional
	// ImageHolder thumbnail
	public ShopExecution addShop(Shop shop, File shopImg) {// throws ShopOperationException {
		// 空值判断
		if (shop == null) {
			return new ShopExecution(ShopStateEnum.NULL_SHOP);
		}
		try {
			// 给店铺信息赋初始值
			shop.setEnableStatus(0);
			shop.setCreateTime(new Date());
			shop.setLastEditTime(new Date());
			// 添加店铺信息
			int effectedNum = shopDao.insertShop(shop);
			if (effectedNum <= 0) {
				throw new ShopOperationException("店铺创建失败");
				//throw new RuntimeException("店铺创建失败");
			} else {
				// if (thumbnail.getImage() != null) {
				if (shopImg != null) {
					// 存储图片
					try {
						addShopImg(shop, shopImg);//thumbnail
					} catch (Exception e) {
						throw new ShopOperationException("addShopImg error:" + e.getMessage());
						//throw new RuntimeException("add shop img 失败");
					}
					// 更新店铺的图片地址
					effectedNum = shopDao.updateShop(shop);
					if (effectedNum <= 0) {
						throw new ShopOperationException("更新图片地址失败");
						//throw new RuntimeException("更新 shop img 失败");
					}
				}
			}
		} catch (Exception e) {
			throw new ShopOperationException("addShop error:" + e.getMessage());
			//throw new RuntimeException("addShop error:" + e.getMessage());
		}
		return new ShopExecution(ShopStateEnum.CHECK, shop);
	}

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

}

下面是imageUtil：

	}

	}

	}
	public static void main(String[] args) throws IOException {

	}
}

同学好，首先，我感觉应该是生成图片的时候，也就是ImgUtil里面的generateThumbnail方法里报错了，但是直接catch了异常并没有抛出，所以看起来是正常的，因此需要在catch异常的地方抛出异常；

其次，没有输出应该是logback.xml配置有问题，可以直接复制粘贴我的试试

  我试试

  非常感谢！我用了您的这个，然后改了在前面PathUtil.java中这行代码： private static String seperator = System.getProperty(“file.separator”); 请注意String seperator 与 file.separator使用的是两个词，如果敲顺手了就会报上面这个错误，就可以了，非常感谢老师的解答。
