如何调试 Struts 2 中的这个错误？
您错过了一个库 struts2-tiles-plugin-x.x.x.x.jar 以及它们的依赖项。
您需要将这些库添加到部署程序集中。它将帮助您存档 ear 项目并包含在其类路径中具有等效清单设置的依赖项。
如果您想了解什么是部署程序集，可以阅读这篇文章Eclipse : Java EE Module Dependencies is replaced by Web Deployment Assembly。
“Web Deployment Assembly“, which provide more powerful and flexible ways to configure the project packaging structure.
还有一个页面描述了将外部资源与ear应用程序链接的过程：Web Application Development: Configuring Projects with External Resources。
您的 war 中有一些 javaee api jar 吗？也许 servlet.jar ？请删除它，然后再检查。
