When logback cannot find configuration file anywhere, it sets the default to send everything to standard output and the level is set to DEBUG. This creates a big problem in our production environment: super-verbose log that is even difficult to look at. My solution was to create a small wrapper using JoranConfigurator. This works great, and I can do whatever I need. However, here is the downside: my code is no longer ignorant of logback. Previously it was purely slf4j everywhere, but now every class is indirectly dependent on logback stuff (though it is limited to 2 lines in every java file). This defeats the purpose of slf4j as pure facade. Is there any better solution? Our problem is, we need to guarantee that no matter what happens in the logging layer, it should never go wild and produce all that debugging noise. ________________________________ This email, along with any attachments, is confidential and may be legally privileged or otherwise protected from disclosure.
