I am trying to configure log4j2 logger. It uses Apache StringSubstitutor.
I want to set default root directory as "${sys:catalina.home}/webapps/${contextName}/logs/". And if property "userRootpath" has been set in logger.properties file, app should use it. I set it as "${bundle:logger:userRootpath}".
To implement this I'm trying to use ":-" variable default value delimiter which described here. But it does not work if I set it as:
<Property name="defaultCatalinaRootpath">${sys:catalina.home}/webapps/${contextName}/logs/</Property>
<Property name="logDir">${bundle:logger:userRootpath:-${defaultCatalinaRootpath}}</Property>
It always just takes ${defaultCatalinaRootpath} and never consider ${bundle:logger:userRootpath} although it has been set in logger.propeties.
If I set directory like this...
<Property name="logDir">${bundle:logger:userRootpath}</Property>
...or this...
<Property name="logDir">${sys:catalina.home}/webapps/${contextName}/logs/</Property>
...it works, so the case is not about corrupted properties initialization.
I tried to initialize properties in different ways inside ":-" structure, but nothing works for me.
How can I achieve desired behavior?
