Fwiw, here's how I setup slf4j/logback. It enables per-runmode logback.xml files
just as with log4j
private def setupLogging() {
import org.slf4j.LoggerFactory
import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.core.util.StatusPrinter;
import ch.qos.logback.classic.joran.JoranConfigurator;
def findTheFile: Box[(_root_.java.net.URL, String)] =
(first(Props.toTry.flatMap(f => {List(f()+"logback.xml")}))
(name =>tryo(getClass.getResource(name)).filter(_ ne null).map(s => (s,
name))))
findTheFile match {
case Full((url, name)) => {
val lc =
LoggerFactory.getILoggerFactory().asInstanceOf[LoggerContext];
val configurator = new JoranConfigurator();
configurator.setContext(lc);
// the context was probably already configured by default
configuration
// rules
lc.reset();
configurator.doConfigure(url);
StatusPrinter.printInCaseOfErrorsOrWarnings(lc);
}
case _ =>
}
Slf4jLogBoot.enable()
}
