本机运行没问题，上传阿里云报错

sdlkjjj

服务器是阿里云centos 6.5 64位，tomcat8，java version "1.8.0_101"，wex v3.5

按照记账本的视频步骤做的，打包后，在本机部署，运行正常，但部署到阿里云服务器报错：

你是用域名访问的还是IP？具体我也不是很了解，有可能是路径问题，服务器访问不到，报了500的错误，我只能和你了解更多的情况，然后帮你请教别人

我用的ip:8080访问


tomcat中带的examples下app访问没问题，说明我的运行环境没问题吧？
下图是我本地运行的截图，说明程序没问题吧？


按照记账本做的，问题出哪里了？
