Ralph Goers commented on LOG4J2-3258:
-------------------------------------
I'm misunderstanding something. You say that properties that originate in the
properties second aren't resolved. I have an app that does
{code:java}
<RollingFile name="log4j"
fileName="${LOG_DIR}/${spring:spring.application.name}.json"
filePattern="${LOG_DIR}/archive/${spring:spring.application.name}.json.%d{yyyyMMdd_HH}-%i">
{code}
and it is working fine.
Second, I need to understand the use case for using the ContextMapLookup in the
name and fileName. Unless you are under the RoutingAppender this doesn't make a
lot of sense since configuration will most likely happen on the main thread the
first time and if you have a monitorInterval specified it could happen on any
thread, so expecting to find it like that seems risky.
