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
