将.war文件部署到tomcat7时无法建立db连接

代码在eclipse环境中使用tomcat7连接到db，但是当我构建一个.war文件并使用命令行和tomcat/manager/html方法部署它时，它不会连接到数据库。
我的应用程序拉到一个登录页面，我试图登录，点击去，我得到的是一个空白的白色屏幕上写着错误。老实说，我对apachetomcat的设置和配置一无所知。我为设置mysql服务器/工作台、apache和eclipse所做的一切都是一条漫长的阅读文档之路。请对我放轻松，我花了4天的时间试图自己解决这个问题，我只是不能理解jndi资源的文档或任何类似的内容。
我不确定您需要查看哪些日志或文件，但下面是示例日志：

上面找不到的文件实际上位于上面的文件夹中，它说它不在：C：\程序文件\ Apache软件基金会\ Tomcat 7 \ WebApp\GCCS\WebINF\Case\Dabase.CONFIG

经过一番研究，我发现了这个问题——最近两个Windows10版本的全新问题。它解释了为什么这不在tomcat-stderr.log中这不是tomcat的问题，而是windows的问题！我编写了一个函数来查找字符串中的%20（因为它们现在是文本，不再是url编码的unc），拆分，然后用空格重新连接字符串并返回新创建的字符串。真管用！该死的Windows！
读了就哭吧！请注意，此支持问题刚刚发布于2018年11月9日。

Apache的Windows安装程序仍然安装到具有名称空间的默认文件夹——C：\程序文件\ Apache软件基金会\Tomcat 9
