之前有需求想把krpano功能化，讓背景全自動生成，但是在網上并沒有看到相關的文章，于是我就對krpano研究了一天，總算給實作了，随着VR的發展，這項技術肯定會有更多的人學習，我就把我研究出來的解決過程分享給大家吧！！！
準備工作：
1.下載下傳krpano-1.19-pr8（我用的是這個版本），下載下傳位址：https://krpano.com/download/，至于破解我就不講了，網上有很多
2.java開發環境
3.tomcat
原理：下載下傳krpano後解壓檔案夾裡有一個批處理：MAKE VTOUR (MULTIRES) droplet.bat，直接把全景圖檔拖動執行這個批處理就會自動生成相應的全景html檔案夾。
廢話不多說，直接上碼：

這些代碼主要意思是用代碼來拖動全景圖檔去執行那個批處理，然後等待生成之後修改生成之後的檔案以及删除一切多餘的檔案，因為我做過N次實驗及對比，我發現執行後生成的很多檔案都是一緻的，是以我就整理了一個通用的包（放在vshow檔案夾），因為生成檔案後必須還得自動釋出，所有vshow這個檔案夾我是直接放在項目裡的：
至于vshow裡的檔案内容你自己生成一次之後保留這些東西就可以了，繼續回到正題，我這個是将全景圖檔上傳了之後，先存放在D:\\temp-room\\裡，然後執行cmd指令自動生成，生成了之後将需要的檔案複制到vshow檔案夾裡，隻要你仔仔細細看我代碼就能明白所有的事情，生成這些檔案處理完後，前台通路就直接用一個通用的jsp檔案來通路，直接貼上我的源碼吧，一定要仔細看代碼，不然真的很難懂：
