在我的ubuntu机器上，这个web应用程序在tomcat上运行良好。但当我在ubuntu服务器上删除它并想要访问它时，它开始创建404错误。我不认为web.xml或pom.xml有什么问题，因为在这种情况下，它不应该部署在我的本地机器上

有什么建议吗

解决.jar之间的冲突应该是第一步。应删除其中一个。

在POM.xml中使用下面的标记

“SLF4J：在类路径上检测到log4j-over-SLF4J.jar和SLF4J-log4j12.jar，抢占StackOverflowerError.SLF4J：另请参阅以获取更多详细信息。org.apache.catalina.core.StandardContext.startInternal Error listenerStart”-为什么不作为第一步修复此问题？@eis Hi，但我的应用程序在本地Tomcat8中运行时，带有相同的log4j警告，并且没有提到关于侦听器启动的任何错误。但为什么在服务器上出现这个错误呢？我真的不知道。您需要进一步调试它，并向我们提供更多详细信息。将调试器附加到Tomcat并找出问题所在。@eis感谢您的评论。我检查了我的本地主机。2014。。。文件，它包含由log4j冲突引起的错误。我会先尝试移除这个东西，然后如果仍然有问题，我会返回给你。@eis你能发布一个答案吗？因为你的观点对我来说是正确的。slf4j是主要问题，目前已得到解决。谢谢你的帮助。
