在尝试了许多示例之后，请最终在http://iambigd.blogspot.com/2011/06/java-upload-file-using-
jersey.html上找到真正有效的示例
@POST@Path("/simpleupload")@Consumes(MediaType.MULTIPART_FORM_DATA)public void simpleUpload( //@Context UriInfo ui, @Context HttpServletRequest request){ String fileRepository = "D:\"; if (ServletFileUpload.isMultipartContent(request)) { FileItemFactory factory = new DiskFileItemFactory(); ServletFileUpload upload = new ServletFileUpload(factory); List<FileItem> items = null; try { items = upload.parseRequest(request); } catch (FileUploadException e) { e.printStackTrace(); } if (items != null) { Iterator<FileItem> iter = items.iterator(); while (iter.hasNext()) { FileItem item = iter.next(); if (!item.isFormField() && item.getSize() > 0) { System.out.println("File is found."); String fileName = processFileName(item.getName()); try { String savePath = fileRepository + fileName; System.out.println("savePath:" + savePath); item.write(new File(savePath)); } catch (Exception e) { e.printStackTrace(); } }else{ System.out.println("getFieldName:" + item.getFieldName()); System.out.println(item.getString()); } } }}}（需要servlet-api.jar，（apache）commons-oi.jar和（apache）commons-fileupload.jar）
