我使用maven archetype blank创建了一个Struts2项目。当我执行mvn jetty：run时，应用程序工作正常。但是，如果我执行“mvn package”并手动部署到Tomcat，应用程序将无法启动。如果我尝试从Eclipse IDE中部署Tomcat 10，则会出现Dito。Prod目标将是Tomcat。
看起来struts2过滤器没有被识别。请参阅下面的两个跟踪。下面是我使用管理器GUI在Tomcat中尝试部署的情况。

第二次跟踪在Eclipse中工作，针对Tomcat部署时，控制台消息显示struts2 filter启动失败，下面是Eclipse中的控制台消息-

你有什么建议吗？这是我尝试过的--
1.我确保eclipse构建路径在类路径上有struts2（6.3.0.2）库。
1.我添加了一个条目，以确保在Project/Properties/Deployment Assembly中选择构建类路径下的Struts2 lib，方法是添加一个条目，并查看它被放置在WEB-INF/lib下
1.我试图寻找一个最近的tomcat插件为maven，但没有找到任何。说明tomcat 8 maven插件不工作。
1.在jetty下构建和运行的其他Struts2示例（在Github上）都不能在Tomcat下运行，如果我做mvn包，然后尝试手动部署。

回到Tomcat 9。Tomcat 10.1使用Jakarta EE 9，这意味着“jakarta”包名，而不是原始的“javax”包名--这就是为什么您会得到关于Filter类型的运行时错误。直到有针对Jakarta EE 9或更高版本的更新的Struts版本，您才能使用Tomcat 10.1。
