我在独立模式下使用Wildfly 10，当我启动Wildfly时，我看到了错误消息
java.lang.ClassNotFoundException: org.jboss.logging.appender.DailyRollingFileAppender from [Module "org.jboss.log4j.logmanager:main" from local module loader @33e5ccce (finder: local module finder @5a42bbf4 (roots: /opt/jboss/modules,/opt/jboss/modules/system/layers/base))]
我解压缩了modules目录下的jar文件，似乎DailyRollingFileAppender类位于org.apache.log4j下，而不是org.jboss.logging。我不确定是否需要进行任何配置。
另一件事是：此错误消息仅显示在控制台上，而不是在我的日志文件中，不确定原因。其他错误消息显示在我的日志文件中。
以下是堆栈跟踪：

谢谢，海伦
答案 0 :(得分：1)
我从Jboss社区得到了帮助，我有一个应用程序，它在war文件中打包了log4j.xml，并使用了org.jboss.logging.appender.DailyRollingFileAppender。此log4j.xml导致此错误消息。在standalone.xml日志记录子系统中将use-deployment-logging-config设置为false可以解决此问题。
