import org.slf4j.LoggerFactory;

public class TestLog {
    private static Logger log = LoggerFactory.getLogger(TestLog.class);
    private static Logger monitorLog = LoggerFactory.getLogger("monitorLog");
    public static void main(String[] args) {
        log.error("zhong1");
        monitorLog.info("zhong");
