代码：
package logbackCfg;import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.Date;import org.slf4j.Logger;import org.slf4j.LoggerFactory;publicclassNewDayThread{privatefinalstaticLogger logger =LoggerFactory.getLogger(NewDayThread.class);publicstaticvoid main(String[] args)throwsInterruptedException{while(true){Date currentTime =newDate();if(currentTime.compareTo(fixedDate())>0){Thread.sleep(8000); logger.info(“万里赴戎机，关山度若飞。”);logger.error(“朔气传金柝，寒光照铁衣。”); logger.debug(“将军百战死，壮士十年归。”);}}}privatestaticDate fixedDate(){SimpleDateFormat formatter =newSimpleDateFormat(“yyyy-MM-dd HH:mm:ss”);try{return formatter.parse(“2020-01-16 10:39:00”);}catch(ParseException e){returnnewDate();}}}
上面代码就是那当前时间与2020-01-16 10:39:00 比较，如果大于则写log。
以下就是线程在设定时间写log的效果：
