你能帮帮我吗？有什么问题？

好的，过滤器有问题。该项目有一个过滤器，它在请求之前加速请求

public class FileUploadServlet extends HttpServlet {

    private static final Log LOG = LogFactory.getLog(FileUploadServlet.class);

    /**
     * {@inheritDoc}
     */
    @Override
    protected void doPost(final HttpServletRequest request, final HttpServletResponse response) throws ServletException, IOException {


        try {
            boolean isMultipart = ServletFileUpload.isMultipartContent(request);
            if (isMultipart) {
                FileItemFactory factory = new DiskFileItemFactory();
                ServletFileUpload upload = new ServletFileUpload(factory);

                List items = upload.parseRequest(request);

                Iterator iter = items.iterator();
                while (iter.hasNext()) {
                    FileItem item = (FileItem) iter.next();
                    if (!item.isFormField()) {
                        LOG.info("Uploading file: " + item.getName());
                        byte[] fileContents = IOUtils.toByteArray(item.getInputStream());
                        //...
                    }
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
