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";
- }
- }
