Question

我只是尝试安装Logback-demo，使用maven打包文件并首次运行demo，但我不断收到这些奇怪的java异常消息：

10:12:03.103 [pool-3-thread-1] INFO  ch.qos.logback.demo.LoggingTask - Howdydy-diddly-ho - 8499

这条消息会反复重复几个小时。关于我做错了什么的任何想法？

Answer 1

根据source code，这看起来很正常：

public class LoggingTask implements Runnable {
  // ... 
  public void run() {
    if(i % 100 == 99) {
      logger.info(HOWDY_MARKER, msg + " - " + (i++), new Exception("e"));
    } else {
      logger.trace("x {]", i++);
    }
  }
}

另请注意，此处不会抛出任何异常，只会记录它。
