Best pattern for reading a FileItem object

I am using the Apache Commons Uploader package, and I am trying to read a file that 开发者_如何学Cis being uploaded. I have a FileItem object.

The first few lines of the file are ASCII and I want to be able to read them and extract the metadata that is contained in them. What is the best method/pattern to go about doing this.

Call getInputStream() on the FileItem, wrap that in a BufferedReader, then read your file line by line using BufferedReader.readLine() until you've read the meta data.

        final List<FileItem> files = new ServletFileUpload(new DiskFileItemFactory())
                .parseRequest(httpRequest.getWrappedRequest());
        final List<Long> images = new ArrayList<>();
        for (final FileItem file : files) {
            if (file.getFieldName().equals("file")) {
                final InputStream stream = file.getInputStream();
                final byte[] bytes = IOUtils.toByteArray(stream);

                ...
                file.delete();
            }
        }
        files.clear();
