Dynamically get handle to logger and log msg in Log4J2 - log4j2

Question

I am trying to programmatically create Log4J2 logger that can be used to log the messages to different files based on the logger name. Below is the method that I have created to log messages dynamically to named file. Files are getting created dynamically but message is not being logged to the created files.
public static synchronized Logger getLogger(String name) {
if (!LogManager.exists(name)) {
LoggerContext lc = (LoggerContext) LogManager.getContext();
Configuration config = lc.getConfiguration();
Appender app = rollingFileAppender(name);
config.addAppender(app);
AppenderRef ref = AppenderRef.createAppenderRef(name, INFO, null);
AppenderRef[] refs = new AppenderRef[]{ref};
LoggerConfig loggerConfig = LoggerConfig
.createLogger(true,INFO, name,"true",refs,null,config,null);
config.addLogger(name, loggerConfig);
config.start();
lc.updateLoggers(config);
// if I comment the method, then msg gets logged to all files that was created dynamically.
//lc.getRootLogger().addAppender(app);
lc.start();
}
return LogManager.getLogger(name);
}
Below is the File Appender that I have created, which is used to create logger.
private static Appender rollingFileAppender(String name) {
LoggerContext ctx = (LoggerContext) LogManager.getContext();
Configuration config = ctx.getConfiguration();
DefaultRolloverStrategy strategy = DefaultRolloverStrategy.newBuilder()
.withMax("20").withMin("1").withFileIndex("max")
.withConfig(config)
.withCompressionLevelStr(String.valueOf(Deflater.NO_COMPRESSION))
.build();
PatternLayout layout = PatternLayout.newBuilder()
.withConfiguration(config)
.withPattern("%d{yyy-MM-dd HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n")
.build();
String logPath = "C:\\Development\\log4J_test\\";
RollingFileAppender rfa = RollingFileAppender
.newBuilder()
.withFileName(logPath + name + ".log")
.withFilePattern(logPath + "/archive/$${date:yyyy-MM}/" + name + "-%d{MM-dd-yyyy}-%i.log.zip")
.withName(name)
.withLayout(layout)
.withPolicy(CompositeTriggeringPolicy.createPolicy(
TimeBasedTriggeringPolicy
.newBuilder()
.withInterval(1)
.withModulate(false)
.build(), SizeBasedTriggeringPolicy.createPolicy("25 MB")
)
).withStrategy(strategy)
.build();
rfa.start();
return RFA;
}
When I run the main method, file1 and file2 are getting created but no msg is being logged.
public static void main(String[] args) {
try {
Properties props = System.getProperties();
props.setProperty("log4j.configurationFile", "<location>\log4j2.xml");
Logger log = getLogger("file1");
log.info("Test log to file1");
log = getLogger("file2");
log.info("Test log to file2");
} catch (Exception e) {
e.printStackTrace();
}
}
Log4J Config file that I have created. Messages are getting logged to mainFile.log
<?xml version="1.0" encoding="UTF-8"?>
