logback \\ log4j-旋转日志文件

Question

I'm looking for a log file, size based, that will only log the last 10MB or so, without rolling older data to archived files. meaning - after 10MB all older data will be deleted, and new entries will be added a row-for-row.

found some policies, but none seem to keep the original file name.

Answer 1

You are supposed to use the following two log4j properties:

log4j.appender.loggerId.MaxFileSize=10MB  
log4j.appender.loggerId.MaxBackupIndex=1

When your file has reached 10Mb log4j will rotate id but keeping at most 1 file as backup.
