Struts 6.3.0.2项目的Mvn构建在tomcat10上部署失败

问题描述 投票：0回答：1

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。如果我尝试从包含 Tomcat 10 的 eclipse IDE 中进行部署，那就是 Dito。产品目标将是 Tomcat。

struts2 过滤器似乎无法被识别。请参阅下面的两条轨迹。下面是我尝试使用管理器 GUI 在 Tomcat 中进行部署时的情况。

第二条痕迹 在 Eclipse 中工作并定位 Tomcat 部署时，控制台消息显示 struts2 过滤器无法启动。下面是 Eclipse 中的控制台消息-

您有什么建议吗？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。

  2. 我添加了一个条目，以确保在项目/属性/部署程序集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

  3. 我尝试寻找最近的maven tomcat插件，但没有找到。 tomcat 8 maven插件的说明不起作用。

  4. 如果我执行 mvn package 然后尝试手动部署，在 jetty 下构建和运行的其他 Struts2 示例（Github 上）都无法在 Tomcat 下运行。

回到 Tomcat 9。Tomcat 10.1 使用 Jakarta EE 9，意思是“jakarta”包名称，而不是原始的“javax”包名称 - 这就是为什么您会收到有关 Filter 类型的运行时错误。在出现针对 Jakarta EE 9 或更高版本的较新 Struts 版本之前，您无法使用 Tomcat 10.1。
