Hello,
yesterday I used the PatternLayout and I wanted to disable the
stacktrace output.
I couldn't find a possibility to do it by configuration.
In cause of that I've patched the ThrowableInformationPatternConverter.
Have a look at the attached patch.
Now you can use the following ConversionPatterns in your property file.
%d{dd MMM yy HH:mm:ss,SSS} |%p|%c{2}| %m %n %throwable{0} - no line of
throwable will be printed out
%d{dd MMM yy HH:mm:ss,SSS} |%p|%c{2}| %m %n %throwable{none} - no line
of throwable will be printed out
%d{dd MMM yy HH:mm:ss,SSS} |%p|%c{2}| %m %n %throwable{3} - three lines
ot throwable will be printed out
...
I hope you like the improvement and apply the patch.
With best regards,
Marcel.
