jquery.from.js 上傳excel用法小結

客戶端程式碼：
h: 100px;" href="javascript:form1()">匯出</a> </td> </tr> </table> </form>
其中客戶端部分name屬性必須填寫，否則後臺接收不到資料
<form id="form1" action="http://localhost:8080/gciwebservice/import/exceltest" method="post" enctype="multipart/form-data"> <table width="100%"> <tr> <td> 請選擇匯入的檔案：<input style="width: 400px" id="fileUrl" name='file' type="file"/> </td> <td></td> <td> <a class="button orange icon check" style="width: 100px;" href="javascript:upload.saveImport()">匯入</a> </td> <!-- 測試匯出 --> <td> <a class="button orange icon check" style="widt
h: 100px;" href="javascript:form1()">匯出</a> </td> </tr> </table> </form>
js程式碼：
upload.saveImport = function(){ var xcl = $("#fileUrl").val(); // var xcl ="C:\fakepath\問題描述.docx"; var strs = new Array(); if(!xcl){ return; } custom.showMask(); strs = xcl.split("."); var suffix = strs[strs.length - 1]; if(suffix!="xls"&&suffix!="xlsx"){ var result = new Object(); result.msgcode = "0"; result.remsg = "檔案格式不正確"; showMsg(result); custom.hideMask(); return; } var form = $("#form1"); var options = { url:'http://'+ localStorage.IPAddress + ':8080/gciwebservice/import/exceltest', type:'post', success:function(data){ var result = new Object(); result.msgcode = "1"; result.remsg = "匯入成功"; showMsg(result); custom.hideMask(); }, error:function(data){ var result = new Object(); result.msgcode = "0"; result.remsg = "匯入失敗"; showMsg(result); custom.hideMask(); } }; form.ajaxSubmit(options); };
後臺用java的servelet接收，程式碼如下：
private static final long serialVersionUID = 1L; private Logger logger = Logger.getLogger(uploadServlet.class); @Override protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { request.setCharacterEncoding("utf-8"); response.setCharacterEncoding("utf-8"); //1、建立一個DiskFileItemFactory工廠 DiskFileItemFactory factory = new DiskFileItemFactory(); //2、建立一個檔案上傳解析器 ServletFileUpload upload = new ServletFileUpload(factory); //解決上傳檔名的中文亂碼 upload.setHeaderEncoding("UTF-8"); factory.setSizeThreshold(1024 * 500);//設定記憶體的臨界值為500K // File linshi = new File("E:\\linshi");//當超過500K的時候，存到一個臨時資料夾中 /* File linshi = new File("/usr/linshi"); factory.setRepository(linshi); */ upload.setSizeMax(1024 * 1024 * 5);//設定上傳的檔案總的大小不能超過5M try { // 1. 得到 FileItem 的集合 items List<FileItem> /* FileItem */items = upload.parseRequest(request); // 2. 遍歷 items: for (FileItem item : items) { // 若是一個一般的表單域, 列印資訊 if (item.isFormField()) { String name = item.getFieldName(); String value = item.getString("utf-8"); logger.info(name + ": " + value); } // 若是檔案域則把檔案儲存到 e:\\files 目錄下. else { String fileName = item.getName(); long sizeInBytes = item.getSize(); InputStream inRead = item.getInputStream(); InputStream inWrite = item.getInputStream(); Map<String ,List> map = readExcel(inRead); inRead.close(); List<TrainSchedulPo> tsplist = map.get("trainSchedul"); ApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext()); CompareUtil compareUtil = (CompareUtil) ctx.getBean("compareUtil"); if(tsplist!=null){ compareUtil.compareTrainSchedule(tsplist); } byte[] buffer = new byte[1024]; int len = 0; String rooturl = request.getServletContext().getRealPath("/"); // fileName = rooturl+"WEB-INF/upload/" + Utils.getNow() +fileName;//檔案最終上傳的位置 fileName = "E:\\files\\"+ Utils.getToday() +fileName;//檔案最終上傳的位置 // fileName = "/usr/"+ Utils.getToday() +fileName;//檔案最終上傳的位置 System.out.println(fileName); logger.info("上傳檔名稱為："+fileName); OutputStream out = new FileOutputStream(fileName); while ((len = inWrite.read(buffer)) != -1) { out.write(buffer, 0, len); } out.close(); inWrite.close(); } } } catch (FileUploadException e) { e.printStackTrace(); logger.error(e,e); } }
