包路径：org.apache.logging.log4j.core.appender.RollingFileAppender
类名称：RollingFileAppender

RollingFileAppender介绍

[英]An appender that writes to files and can roll over at intervals.
[中]一种写入文件并可以每隔一段时间滚动的追加器。

代码示例

代码示例来源：origin: apache/storm

/**
 * Given an appender name, as configured, get the parent directory of the appender's log file.
 * Note that if anything goes wrong, this will throw an Error and exit.
 */
private String logRootDir(String appenderName) {
  Appender appender = ((LoggerContext) LogManager.getContext()).getConfiguration().getAppender(appenderName);
  if (appenderName != null && appender != null && RollingFileAppender.class.isInstance(appender)) {
    return new File(((RollingFileAppender) appender).getFileName()).getParent();
  } else {
    throw new RuntimeException("Log viewer could not find configured appender, or the appender is not a FileAppender. "
        + "Please check that the appender name configured in storm and log4j agree.");
  }
}
