Hello Matt,
the problem is that I want to create the appender and the logger together
via code.
So the appender or the logger are not mentioned in the log4j2.xml file
I am creating the appender via the createAppender factory method but in the
code.
Full code for enable the logger + appender I use is this :
if (enable) {
final LoggerContext ctx = (LoggerContext)
LogManager.getContext(false);
Configuration cfg = ctx.getConfiguration();
if (cfg instanceof XmlConfiguration) {
//add appender if not added
Appender appender = cfg.getAppender(LogStreamAppender.NAME);
if (appender == null) {
appender
= LogStreamAppender.createAppender(LogStreamAppender.NAME, "%highlight{%d
[%t] %-5level: %msg%n%throwable}", "false", null);
cfg.addAppender(appender);
}
//add logger if not added
LoggerConfig logger = ((XmlConfiguration)
cfg).getLogger(loggerName);
if (logger == null) {
logger = new LoggerConfig(loggerName, Level.DEBUG,
false);
cfg.addLogger(loggerName, logger);
} else {
logger.setLevel(Level.DEBUG);
}
logger.addAppender(appender, Level.DEBUG, null);
ctx.updateLoggers(cfg);
}
}
The problem is that indeed this LogStreamAppender is receiving everything
correctly. However in the log4j2.xml I have several other appenders added
at the ROOT log.
<Appenders>
<Console name="CONSOLE" target="SYSTEM_OUT">
<PatternLayout pattern="%highlight{%d [%t] %-5level: %msg%n%throwable}" />
</Console>
.....
</Appenders>
<Root level="info">
<AppenderRef ref="CONSOLE"/>
....
</Root>
All of which .. start automatically receive my Stream log ... which is what
I don't want to happen :(
So even if I pass additivity to false... the root appenders (which were
info but are now as it looks are debug for this package (loggerName)) are
still receiving the messages
Regards,
Nayden
