一篇关于SpringMVC 传统文件上传的方法

一、界面效果

二、html代码

 <legend>上传APK文件</legend>

   <form action="<%=basePath%>/apks/commitApk" class="form-horizontal" method="post" enctype="multipart/form-data">

     <input name="cityCode" value="${s0.paramValue}" type="hidden"/>

     <input name="productCode" value="${s.paramValue}" type="hidden"/>

     <div class="form-group">

          <label for="ticket-message" class="col-sm-3 control-label col-md-1">版本号</label>

          <div class="col-md-4">

             <input type="text" class="form-control" name="versionCode" id="versionCode" placeholder="请输入整数">

          </div>

     </div>

     <div class="form-group">

          <label for="ticket-message" class="col-sm-3 control-label col-md-1">版本名</label>

          <div class="col-md-4">

               <input type="text" class="form-control" name="versionName" id="versionName" placeholder="0.0.0.1">

          </div>

     </div>

     <div class="form-group">

        <label for="ticket-message" class="col-sm-3 control-label col-md-1">描述</label>

        <div class="col-md-4">

            <textarea class="form-control" name="versionDesc" id="versionDesc" rows="5" cols="30" placeholder="版本描述"></textarea>

        </div>

     </div>

     <div class="form-group">

        <label for="ticket-message" class="col-sm-3 control-label col-md-1">文件</label>

        <!-- <label for="ticket-attachment" class="col-sm-3 control-label">请选中apk文件</label> -->

        <div class="col-md-4">

             <input type="file" name="apkFile" id="apkFile">

             <p class="help-block"><em>文件类型: .apk</em></p>

        </div>

    </div>

    <div class="form-group">

         <label for="ticket-message" class="col-sm-3 control-label col-md-1"></label>

         <div class="col-md-4">

              <input id="apkSubmitBtn" type="submit" class="btn btn-danger"></input>

        </div>

    </div>

 </form>

三、后台java代码

 @RequestMapping(value = "/commitApk", method = RequestMethod.POST)

     public @ResponseBody ModelAndView commitApk(@RequestParam("cityCode") String cityCode,@RequestParam("productCode") String productCode,

             @RequestParam("apkFile") CommonsMultipartFile[] apkFile,@RequestParam("versionCode") int versionCode,@RequestParam("versionName") String versionName,

             @RequestParam("versionDesc") String versionDesc, HttpSession session) {

         FileOutputStream out = null;

         FileInputStream in = null;

         try {

             String appPath = System.getProperty("root");

             appPath = appPath.substring(0, appPath.indexOf("ExceptionManageSystem"));

                          StringBuffer buffer = new StringBuffer(appPath + com.tongyan.ems.common.Constants.APKMANAGER_FILES_PAHT);

                          buffer.append(productCode).append("\\").append(cityCode).append("\\");

             File fileDir = new File(buffer.toString());

             if(!fileDir.exists()) {

                 fileDir.mkdirs();

             }

             buffer.append(apkFile[0].getFileItem().getName());

             File file = new File(buffer.toString());

             if(!file.exists()) {

                 file.createNewFile();

             } else {

                 file.delete();//如果存在就删除重新上传

             }

             out = new FileOutputStream(file);

             in = (FileInputStream)apkFile[0].getInputStream();

             int read = 0;

             byte[] b = new byte[1024];

             while((read = in.read(b)) != -1) {

                 out.write(b, 0, read);

             }

             //数据入库

             ApkManagerPo apkManagerPo = new ApkManagerPo();

             apkManagerPo.setApkCode(UUID.randomUUID().toString());

             apkManagerPo.setCreateDate(new SimpleDateFormat(Constants.DATE_FORMAT).format(new Date()));

             apkManagerPo.setProductCode(productCode);

             apkManagerPo.setCustomerCode(cityCode);

             apkManagerPo.setVersionCode(versionCode);

             apkManagerPo.setVersionName(versionName);

             apkManagerPo.setVersionDesc(versionDesc);

             if(session.getAttribute("User") != null) {

                 UserPo user = (UserPo)session.getAttribute("User");

                 apkManagerPo.setUserId(user.getUserId());

             }else {

                 apkManagerPo.setUserId("");

             }

             apkManagerPo.setApkRoute(com.tongyan.ems.common.Constants.FEEDBACK_FILES_PAHT + productCode + "\\" + cityCode + "\\" + apkFile[0].getFileItem().getName());//文件夹放在webApp下面

             apkManagerPo.setApkPath(com.tongyan.ems.common.Constants.FEEDBACK_FILES_URL + productCode + "/" + cityCode + "/" + apkFile[0].getFileItem().getName());

             apkService.addApkVersion(apkManagerPo);

         } catch (Exception e) {

             e.printStackTrace();

         } finally {

              try {

                  if(out != null) {

                      out.close();

                  }

                  if(in != null) {

                      in.close();

                  }

             } catch (IOException e) {

                 e.printStackTrace();

             }

         }

         return null;

     }

此代码为form表单提交，现改需要改为js提交，故做记录

一个用于ajax上传的js插件
