import org.slf4j.Logger;import org.slf4j.LoggerFactory;import ch.qos.logback.classic.LoggerContext;import ch.qos.logback.core.util.StatusPRinter;public class TestLog { private static Logger log = LoggerFactory.getLogger(TestLog.class); private static Logger monitorLog = LoggerFactory.getLogger("monitorLog"); public static void main(String[] args) { LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory(); StatusPrinter.print( lc ); log.error("zhong1"); monitorLog.info("zhong"); }}
