Hi there, it's me again, just wondering, what's the best way to reproduce the behaviour of log4j StringMatchFilter in logback? Do I have to use ch.qos.logback.core.filter.EvaluatorFilter ?
You can re-write StringMatchFilter by extending Filter or AbstractMatcherFilter classes both located in the ch.qos.logback.core.filter package. You could also learn to use EvaluatorFilter with GEventEvaluator (takes an expression in Groovy) or JaninoEventEvaluator (takes an expression in Java. See [1] for details. Re-writing StringMatchFilter should be rather easy and will not require any other dependencies. Using JaninoEventEvaluator will require Janino and GEventEvaluator will require the Groovy runtime. However, JaninoEventEvaluator/GEventEvaluator are much easier to extend should your needs go beyond just string matching on the log message.
