Java Spring 应用程序在 Tomcat7 上部署后无法运行

Question

我刚刚部署（有史以来第一次）基于Spring的Java应用程序。在本地主机上，一切正常，但在部署后，我无法发送任何请求。应用程序只是不在服务器上运行。

有什么问题吗？我将非常感谢任何帮助。

如果它有帮助 - 我已经下载了我刚刚部署在服务器上的示例Web项目，它运行良好。该项目具有上述依赖项，但区别在于部署后的日志。部署该示例应用后，日志中是典型的 Spring 日志：

但是在部署我的应用程序（具有附加的依赖项）之后，没有如上所述的日志。只有应用程序已部署的信息。

问题解决了。问题是Tomcat7的版本导致elManager错误。我已经通过将Tomcat升级到v9解决了这个问题。希望它能对某人有所帮助。话题可以结束了。
