＆＃39; HTTP状态500 - 无法找到taglib＆＃34; s＆＃34;对于URI：/ struts-tags＆＃39;在Ubuntu服务器上部署war文件时出错

Question

我用 Struts2 开发了maven项目。我在 Apache Tomcat 8.5.5 服务器上运行它。该项目的war文件在localhost上运行正常。但是当我在Ubuntu服务器上部署war文件时，它会出错。

我已经阅读了一些文章，他们建议检查我是否添加了struts2-core jar文件。但我已经添加了struts2-core-2.5.2.jar。

寻找解决此问题的一些建议

的pom.xml
