最近項目中使用到了文件從本地到服務器的功能。其實是為了解決目前瀏覽器不支持獲取本地文件全路徑。不得已而想到上傳到服務器的固定目錄,從而方便項目獲取文件,進而使程序支持EXCEL批量導入數據。
在前台界面中 <form method="post" enctype="multipart/form-data" action="../manage/excelImport.do"> 請選文件:<input type="file" name="excelFile"> <input type="submit" value="導入" onclick="return impExcel();"/> </form> action中獲取前台傳來數據並保存 /** * excel 導入文件 * @return * @throws IOException */ @RequestMapping("/usermanager/excelImport.do") public String excelImport( String filePath, MultipartFile excelFile,HttpServletRequest request) throws IOException{ log.info("<<<<<<action:{} Method:{} start>>>>>>","usermanager","excelImport" ); if (excelFile != null){ String filename=excelFile.getOriginalFilename(); String a=request.getRealPath("u/cms/www/201509"); SaveFileFromInputStream(excelFile.getInputStream(),request.getRealPath("u/cms/www/201509"),filename);//保存到服務器的路徑 } log.info("<<<<<<action:{} Method:{} end>>>>>>","usermanager","excelImport" ); return ""; } /** * 將MultipartFile轉化為file並保存到服務器上的某地 */ public void SaveFileFromInputStream(InputStream stream,String path,String savefile) throws IOException { FileOutputStream fs=new FileOutputStream( path + "/"+ savefile); System.out.println("------------"+path + "/"+ savefile); byte[] buffer =new byte[1024*1024]; int bytesum = 0; int byteread = 0; while ((byteread=stream.read(buffer))!=-1) { bytesum+=byteread; fs.write(buffer,0,byteread); fs.flush(); } fs.close(); stream.close(); }
