直接上主要代码：
public class MyCommonsMultipartResolver extends CommonsMultipartResolver implements java.io.Serializable{ private static final long serialVersionUID = 6601669570129283823L; private HttpServletRequest request; @Autowired private MyProgressListener progressListener; ... @Override public MultipartParsingResult parseRequest(HttpServletRequest request) throws MultipartException { HttpSession session = request.getSession(); String encoding = "utf-8"; FileUpload fileUpload = prepareFileUpload(encoding); progressListener.setSession(session); fileUpload.setProgressListener(progressListener); try { List<FileItem> fileItems = ((ServletFileUpload) fileUpload).parseRequest(request); return parseFileItems(fileItems, encoding); } catch (FileUploadBase.SizeLimitExceededException ex) { throw new MaxUploadSizeExceededException(fileUpload.getSizeMax(),ex); } catch (FileUploadException ex) { /* throw new MultipartException("Could not parse multipart servlet request", ex); 这里就不抛异常了 */ //解决上传中断异常的问题。 List<FileItem> fileItems = new ArrayList<FileItem>(); return parseFileItems(fileItems, encoding); } } ... }接下来，在文件上传控制器里if(multipartFile==null){return;}一下就可以了
