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"));
            11             StringBuffer buffer = new StringBuffer(appPath + com.tongyan.ems.common.Constants.APKMANAGER_FILES_PAHT);
            13             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
