org.apache.catalina.LifecycleException：无法启动组件 [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]] - tomcat 8.5
org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]] - tomcat 8.5
我正在尝试让我的 tomcat 8.5 开始使用我的日食。
每次我收到这个错误。
我已经尝试了以下修复，但似乎没有任何效果：
- 已将 log4j.jar 添加到我的类路径
- 已清理 Tomcat 目录
- 我的JDK是1.8
- 我的 JRE 是 1.8
知道还可以尝试什么吗？

我发现了我的问题。
我的 lib 文件夹在 WebContent 文件夹之外...
我将其复制到 WebContent/WEB-INF 中，现在一切正常
