调用:

@ResponseBody
    @RequestMapping(value = "/getApkVersion", method = RequestMethod.POST)
    public String getApkVersion(VersionForm form, MultipartFile apkFile) throws Exception {

        File apkTempFile = new File(DictInit.dictMap.get(Constant.Dict.APK_UPLOAD_PATH) + "temp.apk");
        // File apkTempFile = new File("d:\\temp.apk");//测试用
        apkFile.transferTo(apkTempFile);
        // 获得apk信息
        ApkInfo apkInfo = new ApkInfo();
        apkInfo = ApkUtil.getApkInfo(apkTempFile.getPath());
        return apkInfo.getVersionName();
