我根据以下内容构建了我的基座应用程序

https://github.com/pedestal/pedestal/blob/master/guides/documentation/service-war-deployment.md

然后我上传 .war 文件并部署它。

但是，当我 ssh 到 ec2 实例时，我发现它没有成功部署，即使它这么说

我认为这是特定于基座的，因为我成功地部署了一个打包到战争中的 clojure ring Web 应用程序而没有问题。

从查看堆栈跟踪来看，似乎缺少这个类：org/apache/tomcat/util/descriptor/tld/TldParser.

您提供的超级战争可能仍然包含 Tomcat 类。您链接到的说明以删除 Tomcat 依赖项：

[io.pedestal/pedestal.tomcat "0.1.0"]

我猜EC2提供了它自己的 Tomcat，如果你没有提供任何冲突的类，你就不会得到那个错误。

您可以使用任何 zip/归档工具查看战争内部并验证您是否已完全删除 Tomcat：毕竟它只是一个 zip 文件。
