java 封装前台数据(一)

   现在我觉得前台没有必要在用前台数据填充javabean来传向后台来处理数据,如果一个程序有几百个表,是不是要用几百个javabean呢?   把前台所有传向后台的数据封装成Map,传向后台也一样处理.public boolean isMultipart() {return !StringUtils.isBlank(request.getContentType()) && request.getContentType().indexOf("multipart/form-data") > -1;}private Map<String, Object> createParamMap() {if (isMultipart()) {// 上传文件处理DiskFileItemFactory factory = new DiskFileItemFactory();ServletFileUpload upload = new ServletFileUpload(factory);List<FileItem> fileItemList = null;try {fileItemList = upload.parseRequest(request);} catch (Exception e) {throw new ServiceException(e);}for (FileItem fileItem : fileItemList) {if (fileItem.isFormField()) {paramMap.put(fileItem.getFieldName(), fileItem.getString());} else if (fileItem.getSize() > 0) {if (!paramMap.containsKey(fileItem.getFieldName())) {paramMap.put(fileItem.getFieldName(), new ArrayList<FileItem>());}((List) paramMap.get(fileItem.getFieldName())).add(fileItem);}}}{Enumeration paramNames = request.getParameterNames();if (paramNames != null) {while (paramNames.hasMoreElements()) {String paramName = (String) paramNames.nextElement();String paramValue = request.getParameter(paramName);if (paramName != null && !paramName.equals("")) {       paramMap.put(paramName, paramValue);}}}}return paramMap;}
