Re: Using CompositeFilter on appender with properties configuration

[Oliver Limberg <ok...@gmail.com>]

I finally had time to look into this again and managed to find a solution:

The type one has to use for a CompositeFilter is ‘filters’.
Afterwards you just specify the various filters below the same key.
Here a working example of a CompositeFilter on an appender:

appender.console.type = Console
appender.console.name = Console
appender.console.target = SYSTEM_OUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = %d [%t] %-5level: %msg%n%throwable
appender.console.filter.composite.type = filters
appender.console.filter.composite.threshold.type = ThresholdFilter
appender.console.filter.composite.threshold.level = WARN
appender.console.filter.composite.regex.type = RegexFilter
appender.console.filter.composite.regex.regex = expected resource not found: /META-INF/javamail\\.default\\.(providers|address\\.map)
appender.console.filter.composite.regex.onMatch = DENY
appender.console.filter.composite.regex.onMismatch = NEUTRAL
Best Regards
Oliver
