http://stackoverflow.com/questions/20819376/log4j2-rollingfile-appender-add-custom-info-at-the-start-of-each-logfile
I want to add some custom info at the top of each logfile, like the version
string of my application, the application uptime and the system uptime. And
even writing some »bye, bye / eof« to the bottom of the just closed logfile
would also be fine.
Because there is no appropriate hook or callback to get notified when the
RollingFileAppander is creating / has created a new file, so that I can put my
things at first into these new logfile, I tried to extend
DefaultRolloverStrategy. But currently, I stuck at some points.
Seems that I have to deal with {{@Plugin}} and {{@PluginFactory}}. My try with
the attached log4j2.xml and MyRolloverStrategy.java compiles without errors and
warnings. But when I start the application, I get this error message:
{{2014-01-05 23:22:05,876 ERROR RollingFile contains an invalid element or
attribute "MyRolloverStrategy"}}
