Issue
how to pass? The only way I can get this to work is to put log4j.xml on the classpath.
passing: -Dlog4j.configuration=file:///c:\log4j2.xml on the command line doesn't work (although it does in a non spring-boot test application just fine).
I also tried putting this as an environment variable/property in spring.
Solution
Try to put this line into your application.properties:
logging.config=file:log4j.xml
Second option is to pass system variable to -Dlogging.config=file:log4j.xml
In this case it is expected to be located in current directory outside of the JAR file.
