如何使log4j滚动到日志文件名或模式？

Question

I was able to get the current log file name with this fragment of code:

Enumeration allAppenders = org.apache.log4j.Logger.getRootLogger().getAllAppenders();

while (allAppenders.hasMoreElements())
{
   Object appender = allAppenders.nextElement();

   if (appender instanceof FileAppender)
   {
      File logFile = new File(((FileAppender) appender).getFile());
      break;
   }
}

But if I have rolled over log files, how do I get their names?

It seems like it's not guaranteed that rolled over log files start with logFile.getName() as its prefix.

我认为您应该检查org.apache.log4j.RollingFileAppender和/或org.apache.log4j.DailyRollingFileAppender （取决于您使用的滚动类型），并使用自己的特定方法，例如，对于DailyRollingFileAppender使用getDatePattern（）
