Question

我无法初始化log4j catalina log appender - 你知道我错过了什么吗？我知道这是一个基本问题，但我仍然坚持这一点。我为catalina记录器添加了一个org.apache.log4j.net.SyslogAppender定义，但没有运气。

log4j：警告没有找到记录器的附加程序（org.apache.catalina.startup.Catalina） log4j：WARN请正确初始化log4j系统

据我所知，我正在使用-log4j.xml初始化log4j系统 - 我做错了什么？我再次知道这是一个基本问题。这是我的/src/main/resources/log4j.xml文件。

这是tomcat7-maven-plugin的配置，我知道它很大，我为所需的配置量道歉：

当我手动指定log4j.xml文件的位置时，日志记录正常工作。

$ mvn tomcat7:run -DskipTomcat=false -Dlog4j.configuration=file:src/main/resources/log4j.xml

有什么显而易见的东西吗？

Answer 1

您可以将log4j.properties或XML添加到systemProperties部分：
