翻来覆去检查路径，并DEBUG，之前在写ImageUtil时的main函数时也成功输出了一张打印好水印的图片，但是这次test时就一直报错，图片路径都是用的绝对路径，DEBUG时也能读到目标图片的路径，比对代码也没有错，这次实在是不知道出啥问题了

ImageUtil

public class ImageUtil {
private static String basePath = Thread.currentThread().getContextClassLoader().getResource("").getPath();
private static final SimpleDateFormat sDateFormat = new SimpleDateFormat(“yyyyMMddHHmmss”);
private static final Random r = new Random();
private static Logger logger = LoggerFactory.getLogger(ImageUtil.class);

/*将CommonsMultipartFile转换为File*/
public static File transferCommonsMultipartFileToFile(CommonsMultipartFile cFile)
{
    File newFile = new File(cFile.getOriginalFilename());
    try {
        cFile.transferTo(newFile);
    } catch (IllegalStateException e) {
        logger.error(e.toString());
        e.printStackTrace();
    }catch (IOException e)
    {
        logger.error(e.toString());
        e.printStackTrace();
    }
    return newFile;
}
/*处理缩略图，并返回目标图片的相对值路径*/
public static String generateThumbnail(File thumbnail, String targetAddr)
{
    String realFileName = getRandomFileName();
    String extension = getFileExtension(thumbnail);
    makeDirPath(targetAddr);
    String relativeAddr = targetAddr + realFileName + extension;
    logger.debug("current relativeAddr is :"+relativeAddr);
    File dest = new File(PathUtil.getImgBasePath()+relativeAddr);
    logger.debug("current complete addr is :"+ PathUtil.getImgBasePath()+relativeAddr);
    try {
        Thumbnails.of(thumbnail).size(300,600).watermark(Positions.BOTTOM_RIGHT,
                ImageIO.read(new File("D:/实训文件/pic/watermark.png")),0.25f).outputQuality(0.8f)
                .toFile(dest);
    }catch (IOException e)
    {
        logger.error(e.toString());
        e.printStackTrace();
    }
    return relativeAddr;
}



/*生成随机文件名，当前年月日小时分钟秒钟+五位随机数*/
private static String getRandomFileName()
{
    //获取随机的五位数
    int rannum = r.nextInt(89999)+10000;
    String nowTimeStr = sDateFormat.format(new Date());
    return nowTimeStr + rannum;
}

/*获取输入的文件扩展名*/
private static String getFileExtension(File cFile)
{
    String originalFileName = cFile.getName();
    return originalFileName.substring(originalFileName.lastIndexOf("."));
}

private static void makeDirPath(String targetAddr) {
    String realFileParentPath = PathUtil.getImgBasePath() + targetAddr;
    File dirPath = new File(realFileParentPath);
    if (!dirPath.exists())
    {
        dirPath.mkdirs();
    }
}

PathUtil

public class PathUtil {
private static String seperator = System.getProperty(“file.separator”);
public static String getImgBasePath()
{
String os = System.getProperty(“os.name”);
String basePath = “”;
if(os.toLowerCase().startsWith(“win”))
{
basePath = “D:/实训文件/pic/”;
}
else
{
basePath = “/Users/AboutO2O/image/”;
}
basePath = basePath.replace("/", seperator);
return basePath;
}

public static String getShopImagePath(long shopId) {
    String imagePath = "/upload/images/item/shop/" + shopId + "/";
    return imagePath.replace("/", seperator);
}

}

第一处57行那个错是CATCH捕获到并抛出异常
第二处43行就是异常的代码处，相关test类里的 ShopExecution se = shopService.addShop(shop,ShopImg);
