This is a case where I would recommend the application be modified, if
possible, to use a Marker. Instead of using a RegEx filter as Matt shows, which
can be expensive if you have lots of logging, you could use the MarkerFilter.
To do this, everywhere you log “Creating shared instance of singleton bean” or
something else you would like to optionally suppress create a Marker and add it
as a filter:
public static final Marker VERBOSE = MarkerManager.getMarker(“VERBOSE”);
logger.debug(VERBOSE, “Creating shared instance of singleton bean {}”,
className);
<Logger name=“com.example.thing” level=“DEBUG”>
<MarkerFilter marker=“VERBOSE” onMatch=“DENy” onMismatch=“NEUTRAL”/>
</Logger>
The usage of the filter is exactly as Matt explained regardless of which filter
you use.
