【Java】自建IOS应用（IPA）发布服务器

       简单描述一下总的过程：在某个后台上（版本发布平台）上传原始的ipa文件，解析ipa（主要是解析info.plist，从中获取软件名、版本、icons等；解析embedded.mobileprovision，获取证书过期时间），生成一个新的plist文件，最终将ipa、新的plist、图标上传至发布服务器。这个plist文件里面会指向这个ipa的地址，最终在Safari上访问 itms-services://?action=download-manifest&url=plist文件 就可以下载IOS应用了。

下面先来看看最重要的plist文件.

一、服务器

首先，我们需要一台服务器，并且有SSL证书。这是因为最终在Safari上访问plist文件需要。

二、解析IPA

FileService这里主要用到就是在本地构造临时文件，ClientVersionRecord是数据库存储的版本实体对象，比较简单，不再赘述。

controller入口可以见：https://blog.csdn.net/Mr_EvanChen/article/details/106937688
