Hi, im wondering if i could have some help with migrating from log4j1 to log4j2
please?
Im trying to update gerrit to log4j2 but am stuck on some things. [1]
1. How do i migrate from
PropertyConfigurator.configure(Loader.getResource(LOG_CONFIGURATION)); to
something log4j2 compatible please?
Im trying to migrate all the way without trying to use log4j1 compatible api
log4j2. (Though im still pulling it in i am trying not to use it).
I found doing something like
String path = System.getProperty(JAVA_OPTIONS_LOG_CONFIG); if
(Strings.isNullOrEmpty(path)) { ConfigurationSource source =
ConfigurationSource.fromResource(LOG_CONFIGURATION, null);
Configurator.initialize(null, source); } else { URL in = new URL(path);
Configurator.initialize((String) null, null, in.toURI()); }
could work but then it wont reload the configuation without restarting the
configuation as new (ie gets rid of everything). which .reconfigure() does.
Im trying to reset log levels to null so that we can reload the configuation
but reconfigure gets rid of everything thus causing problems if you used java
to add appenders or anything else. see [2]
Also how would i migrate from using removeAllAppenders to log4j2 compatible
code please?
