這個必須記錄一下；
使用：SpringBoot+Mybatis+SqlServer2016+阿里連接池
部署：打包jar，在客戶私有服務器上運行，客戶服務器是Windows Server 2016
問題：剛開始直接無法啟動，報如下錯誤，起初是重啟服務器解決的，因為服務器上還運行這其他幾個服務軟件，主要就數據接收和存儲功能，剛開始猜測是他們軟件影響的，因為查看了端口占用情況太多了，基本所有端口都被占用了，好幾頁，剛開始沒理他就這么運行着，后來因為程序調整又重啟了一兩次服務器，重啟服務器太費勁，也不是解決問題的辦法；下面看我的解決方法

解決方案：網上看了好多資料，參考這個連接https://blog.csdn.net/yzy199391/article/details/78911329?utm_medium=distribute.pc_feed_404.none-task-blog-2~default~BlogCommendFromBaidu~default-1.control404&depth_1-utm_source=distribute.pc_feed_404.none-task-blog-2~default~BlogCommendFromBaidu~default-1.control40，主要說是WindowsServer服務器bug，需要打補丁，我就找補丁，微軟官網還下載不了，后來在這下載的http://thehotfixshare.net/board/index.php?/files/file/13913-windows61-kb2577795-x64msu/；
下載完成后去安裝，結果安裝不了報錯了，尼瑪，
網上各種找問題，幾個簡單的方法都試了，不好使，因為是客戶的服務器不敢大搞，反正就是解決不了；后來繼續查找起初的問題，終於看到了這片文章https://blog.csdn.net/woshiji594167/article/details/81874095?spm=1001.2101.3001.6650.1&utm_medium=distribute.pc_relevant.none-task-blog-2%7Edefault%7ECTRLIST%7Edefault-1.opensearchhbase&depth_1-utm_source=distribute.pc_relevant.none-task-blog-2%7Edefault%7ECTRLIST%7Edefault-1.opensearchhbase；
這片文章其實錯誤信息和我的不太一樣，抱着試試的態度去試了了，結果程序啟動起來了；沒錯了，深入的研究不明白，主要看大神們的文章；不管怎么樣先告一段落，回頭在出問題繼續找，寫給同樣遇到這個問題的戰友們，希望你們不要和我是的用一天的時間去找這個問題；
文才有限，也不太會弄格式，我盡量寫詳細了，希望能幫到大家；謝謝
