在 Tomcat7 上部署后，Java Spring 应用程序无法运行

Question

我刚刚部署（有史以来第一次）我的基于 Spring 的 Java 应用程序。 在本地主机上一切正常，但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？ 对于任何帮助，我将不胜感激。

如果有帮助 - 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，但部署后的日志有所不同。 部署该示例应用程序后，日志中是典型的 spring 日志：

但是在部署我的应用程序（带有附加依赖项）之后，没有像上面那样的日志。 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。 我只是通过将 Tomcat 升级到 v9 来解决这个问题。 希望它会对某人有所帮助。 话题可以关闭。
