我有一个使用 Spring Boot 运行良好的 Java webapp，并且我一直在使用 SLF4J（带有 log4j2）。这一切都有效 - 并注销到正确的文件 - 在我的本地 Tomcat 实例中，该实例在类路径中没有冲突的 Jars。

但是，当部署到生产环境中时，Tomcat/lib 目录中似乎有一个现有的 log4j jar 文件（这胜过我自己在 WEB-INF/lib 目录中的 log4j2 jar 文件）。我在启动时遇到一些错误，这些错误似乎与我自己的配置无关，因为记录器/属性的数量不匹配。

我对生产 Tomcat 环境的控制有限，所以理想情况下，我希望能够单独限制哪些库包含在我的 webapp的类路径中，而无需更改部署在同一 Tomcat 实例中的其他库的配置。

因此，我的问题是：是否可以仅从我的应用程序中排除提供的 log4j jar，而使用我提供的 log4j2 jar？

提前致谢！
