java全自动生成krpano全景漫游

之前有需求想把krpano功能化，让后台全自动生成，但是在网上并没有看到相关的帖子，于是我就对krpano研究了一天，总算给实现了，随着VR的发展，这项技术肯定会有更多的人学习，我就把我研究出来的解决过程分享给大家吧！！！


准备工作：

  1.下载krpano-1.19-pr8（我用的是这个版本），下载地址：https://krpano.com/download/，至于破解我就不讲了，网上有很多

2.java开发环境

3.tomcat

原理：下载krpano后解压文件夹里有一个批处理：MAKE VTOUR (MULTIRES) droplet.bat，直接把全景图片拖动执行这个批处理就会自动生成相应的全景html文件夹。

废话不多说，直接上码：

这些代码主要意思是用代码来拖动全景图片去执行那个批处理，然后等待生成之后修改生成之后的文件以及删除一切多余的文件，因为我做过N次实验及对比，我发现执行后生成的很多文件都是一致的，所以我就整理了一个通用的包（放在vshow文件夹），因为生成文件后必须还得自动发布，所有vshow这个文件夹我是直接放在项目里的：



至于vshow里的文件内容你自己生成一次之后保留这些东西就可以了，继续回到正题，我这个是将全景图片上传了之后，先存放在D:\\temp-room\\里，然后执行cmd命令自动生成，生成了之后将需要的文件复制到vshow文件夹里，只要你仔仔细细看我代码就能明白所有的事情，生成这些文件处理完后，前台访问就直接用一个通用的jsp文件来访问，直接贴上我的源码吧，一定要仔细看代码，不然真的很难懂：
