无法在WebSphere Liberty配置文件中为多个应用程序配置log4j

Question

我在liberty中部署了多个WebApp，它们都有自己的log4j配置文件，每个WAR中的log4j配置文件位于WAR的WEB-INF/classes文件夹中。添加log4j配置的web.xml代码片段如下：

<context-param>
                <param-name>log4jConfiguration</param-name>
                <param-value>classpath:portal-log4j2.xml</param-value>
        </context-param>

这似乎适用于所有其他Tomcat和Jboss应用服务器，但不适用于WebSphere Liberty Profile。即使在WebSphere Basic profile中，似乎也是如此。在JVM.options中指定-dlog4j.configurationFile对我来说不起作用，因为我有多个应用程序

我查看了Websphere Liberty：如何指定log4j2配置位置？

也试过同样的。对我来说，这导致了以下错误

非常感谢对此的任何指导

我与IBM support的Brian一起解决了这个问题。似乎这个问题是Liberty上的Log4J22.8特有的，升级到V2.13解决了这个问题。有关详情，请参阅以下内容：
