You can your existing authapi.jar: "Log4j 2 provides support for the Log4j 1 logging methods by providing alternate implementations of the classes containing those methods. These classes may be found in the log4j-1.2-api jar distributed with the project. All calls to perform logging will result in the data passed to the logging methods to be forwarded to the Log4j2 API where they can be processed by implementations of the Log4j 2 API."

Re: loggerConfig.getAppenderRefs().clear()
Matt's suggestion works. You can make a routing appender that will switch
between appenders under program control. Example of something that switches
between two different ConsoleAppenders
Configuration:
Component to do the ablookup:
package org.wegscd;
import org.apache.logging.log4j.core.LogEvent;
import org.apache.logging.log4j.core.config.plugins.Plugin;
import org.apache.logging.log4j.core.lookup.StrLookup;
@Plugin(name = "ablookup", category = StrLookup.CATEGORY)
public class ABLookup implements StrLookup {
static String ab;
public ABLookup() {
System.out.println ("ABLookup instantiated");
}
@Override
public String lookup(String key) {
if (key.equalsIgnoreCase("ab")) {
return ab;
}
return null;
}
@Override
public String lookup(LogEvent event, String key) {
return lookup(key);
}
public static void setAB(String _ab) {
ab = _ab;
}
}
Test Program: import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.wegscd.ABLookup;
public class MainAB {
static Logger logger;
public static void main(String[] args) {
System.setProperty("log4j2.configurationFile", "ab.xml");
logger = LoggerFactory.getLogger(MainAB.class);
logger.warn ("Start (goes nowhere, since ab is not set");
ABLookup.setAB("A");
logger.info("this should go to ConsoleA");
ABLookup.setAB("B");
logger.info("this should go to ConsoleB");
logger.warn ("Done");
}
}
Output
ABLookup instantiated
ConsoleA this should go to ConsoleA
ConsoleB this should go to ConsoleB
ConsoleB Done

Take a look at this:

This appender is extremely flexible for that use case. I'd recommend
avoiding the use of an inline script (JavaScript or Groovy) unless
absolutely necessary as that's likely the slowest routing mechanism
(though you could always benchmark that).

you are trying to clear the list of appenderRefs. Are you trying to call clearAppenders() instead of clear()?

Re: removeAllAppenders() Log4j2
I understand that, but am trying to help you find a solution that works with 2.x. While your code removed all the appenders in 1,x, that might not be necessary under 2.x, but I can't help you with that if you don't share more information about why the appenders need to be removed. If you share that information, I (or someone else) might be able to help you get your application converted over to 2.x. That being said, you are welcome to try the #clearAppenders().

Re: getAppender
There is no appender named "LoggerLog4jDebug". The appender is probably
"LoggerLog4jDebugAppender"?

yes, that works as designed, but does not resolve my problem. The filename is not evaluated when the first event is written (after we have a good date/time), it's evaluated when log4j2 is configured (which is before when we have a good date/time set).
