我是struts新手，我尝试了我的第一个程序，但在本地主机上启动tomcat v9.0时出现的错误显示遇到了一个问题，我尝试了许多方法来解决这个问题，但没有解决 我的代码如下，我被添加了所有库，但我仍然得到这个错误

web.xml

struts.xml

我找到了这个问题的解决方案我添加了struts 2的所有jar，因此它会产生冲突我删除了所有jar，然后再次插入jar，这是必需的，而且我在web中犯了一个小错误。xml筛选器名称不同，必须相同

一般来说，实际包含错误是有帮助的。以及Struts 2的版本。以及pom.xml，如果您手工进行依赖关系管理，那么您不应该手工进行依赖关系管理，您正在部署的库以及如何进行依赖关系管理。并一致地缩进所有代码；如果没有适当的缩进和空白，阅读起来会困难得多。我在部署项目时使用struts2，在本地主机上启动tomcat v9.0时出错遇到问题，但同一台服务器在其他项目中工作正常任何建议什么版本？日志里有什么？实际的错误是什么？如果您不提供任何可操作的东西，我不知道您期望什么。当我运行index.jsp时，我在本地主机上得到错误tomcat v9.0遇到了问题，所以我的代码中有什么错误，请建议Struts 2的版本是什么？日志里有什么？实际的错误是什么？如果你不提供任何可采取行动的东西，我不知道你期望什么。
