我可以在Web应用程序中使用log4j而不使用log4j.xml或log4j.properties以外的文件吗？

Question

Is it possible to use something other than the file names log4j.xml or log4j.properties to configure log4j logging in a Java web application?

I want to load a log4j.xml file from a different location on the file path (not in my classpath). Is that possible in a web application using say, JBoss or Tomcat?

Answer 1

您可以使用PropertyConfigurator。使用所需的文件调用configure

Answer 2

Use -Dlog4j.configuration=path/to/your/file.xml startup parameter to specify where your configuration file is. It's the recommended practice anyway:

The preferred way to specify the default initialization file is through the log4j.configuration system property.
