Question

我想从路径字符串创建指向我计算机上的jpg文件的输入流。但是，我收到此错误：

java.io.FileNotFoundException： C：\ Users \ bnbih \ Downloads \ tmp.zip \ tmp \ 2227795.jpg（系统不能找到指定的路径）

但是，该文件确实存在于我的计算机上，我可以从同一路径创建一个File对象。

这是我的所有参考代码：

/**detects if the user uploaded ZIP file*/
        if(zipFile.getSize() != 0){

            Path zipPath = Paths.get(zipFile.getSubmittedFileName());//get the path for the zip file
            String zipFileName = zipPath.getFileName().toString();//gets the zip file name with ext

            //create a file system to manipulate the files
            FileSystem fs = FileSystems.newFileSystem(zipPath, null);

            /**create an iterator over all the individual image files 
             * based on the assumption the the zip file structure is testZIP->testZIP->individual images*/
            Iterator<Path> it = Files.walk(fs.getPath("/" + getRawName(zipFileName))).iterator();

            //while there're images in the ZIP
            while(it.hasNext()){
                //gets the path of the current image
                Path currentImage = it.next();

                //constructs an image file based on path (works fine)
                File currentFile = new File(zipFile.getSubmittedFileName(), currentImage.toString());

                //holds the type of the file (to test if its a JPG image)
                String fileType= new MimetypesFileTypeMap().getContentType(currentFile);

                //checks if current file is JPG image
                if(fileType.equals("image/jpeg")){
                  //create path for the current path
                  Path pt = Paths.get(zipFile.getSubmittedFileName(), currentImage.toString());

                  //create input stream based on pt (where error appears even though it is the same path as the File object above)
                  InputStream curImgStr = new FileInputStream(pt.toString());
                  /**make input stream for the file to be inserted as blob in SQL*/

                  //fills zipMap with GUID and image file pair
                  zipMap.put(getRawName(currentImage.getFileName().toString()), curImgStr);

                //Files.copy(currentImage, Paths.get(System.getProperty("user.home"), "/tesoo/foo" + i + ".jpg"), REPLACE_EXISTING);

                }//end of if that checks if file is a JPG image
            }//end of while 
        }//end of if that checks if ZIP was uploaded

这是整个错误：

这是我电脑的路径：

C：\ Users \ bnbih \ Downloads \ tmp.zip \ tmp，文件在里面

即使该文件存在，我收到java.io.FileNotFoundException。 Java的
