记述一下步骤以备查。
准备工作:
需要把Jakarta Commons FileUpload及Jakarta Commons io的包放lib里。
我这边的包是:
commons-fileupload-1.1.1.jar
commons-io-1.3.2.jar
然后在spring-servlet.xml进行multipartResolver配置,不配置好上传会不好用。
<bean id=\"multipartResolver\" class=\"org.springframework.web.multipart.commons.CommonsMultipartResolver\"> <property name=\"maxUploadSize\"><value>100000</value></property> <property name=\"defaultEncoding\"><value>UTF-8</value></property> </bean>
接下来就是页面了:
注意Form的写法和文件上传组件的写法。
<form action=\"uploadPosdetailFile.html\" method=\"post\" ENCTYPE=\"multipart/form-data\"> <div class=\"form\" > <p> <span class=\"req\"><input id=\"startDateTxt\" name=\"startDateTxt\" class=\"field size4\" title=\"Enter the date\" /></span> <label>Start Date: <span>(Date format:MM/dd/yyyy,eg:01/01/2014)</span></label> </p> <p> <span class=\"req\"><input id=\"endDateTxt\" name=\"endDateTxt\" class=\"field size4\" title=\"Enter the date\" /></span> <label>End Date: <span>(Date format:MM/dd/yyyy,eg:12/25/2014)</span></label> </p> <p> <span class=\"req\"><input type=\"file\" name=\"uploadFileCtrl\" class=\"field size4\" title=\"Choose the file\" /></span> <label>Upload file: <span>(click browse to choose)</span></label> </p> </div> <div class=\"buttons\"> <input id=\"queryBtn\" type=\"Submit\" class=\"button\" value=\"Submit\" /> </div> </form>
再在控制器里写处理代码,注意参数和页面控件的对应关系:
@RequestMapping(value=\"/uploadPosdetailFile\") public String uploadPosdetailFile(@RequestParam(\"startDateTxt\") String startDateTxt, @RequestParam(\"endDateTxt\") String endDateTxt, @RequestParam(\"uploadFileCtrl\") MultipartFile file,HttpServletRequest request,HttpServletResponse response){ try { System.out.println(\"@@@@@@@@@1.startDateTxt=\"+startDateTxt); System.out.println(\"@@@@@@@@@2.endDateTxt=\"+endDateTxt); System.out.println(\"@@@@@@@@@3.file=\"+file.getOriginalFilename());// 得到上传文件的文件名 if(file.isEmpty()==false){ InputStream is=file.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader br=new BufferedReader(isr); String s; while((s=br.readLine())!=null ){ System.out.println(s); } br.close(); isr.close(); is.close(); } return \"/pages/posdetail/uploadposdetailresult/index.jsp\"; } catch (Exception e) { e.printStackTrace(); logger.error(e); request.setAttribute(\"error\", e.getClass()); request.setAttribute(\"reason\", e.getMessage()); StackTraceElement[] arr=e.getStackTrace(); request.setAttribute(\"stackTraceElements\", arr); return \"pages/error/index.jsp\"; } }
