这个必须记录一下；
使用：SpringBoot+Mybatis+SqlServer2016+阿里连接池
部署：打包jar，在客户私有服务器上运行，客户服务器是Windows Server 2016
问题：刚开始直接无法启动，报如下错误，起初是重启服务器解决的，因为服务器上还运行这其他几个服务软件，主要就数据接收和存储功能，刚开始猜测是他们软件影响的，因为查看了端口占用情况太多了，基本所有端口都被占用了，好几页，刚开始没理他就这么运行着，后来因为程序调整又重启了一两次服务器，重启服务器太费劲，也不是解决问题的办法；下面看我的解决方法

解决方案：网上看了好多资料，参考这个连接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，主要说是WindowsServer服务器bug，需要打补丁，我就找补丁，微软官网还下载不了，后来在这下载的http://thehotfixshare.net/board/index.php?/files/file/13913-windows61-kb2577795-x64msu/；
下载完成后去安装，结果安装不了报错了，尼玛，
网上各种找问题，几个简单的方法都试了，不好使，因为是客户的服务器不敢大搞，反正就是解决不了；后来继续查找起初的问题，终于看到了这片文章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；
这片文章其实错误信息和我的不太一样，抱着试试的态度去试了了，结果程序启动起来了；没错了，深入的研究不明白，主要看大神们的文章；不管怎么样先告一段落，回头在出问题继续找，写给同样遇到这个问题的战友们，希望你们不要和我是的用一天的时间去找这个问题；
文才有限，也不太会弄格式，我尽量写详细了，希望能帮到大家；谢谢
