sl4j and logback - Is it possible to programmatically set the logging level for package?

Question

I'm able to programmatically set the logging level on the application with the following code, but is it also possible to do this on a package level, say com.somepackage.* where I want the level to be only ERROR rather than DEBUG or INFO on said package?

// Sets the logging level to INFO LoggerContext loggerContext = (LoggerContext)LoggerFactory.getILoggerFactory(); Logger rootLogger = loggerContext.getLogger(Logger.ROOT_LOGGER_NAME); rootLogger.setLevel(Level.INFO); 

But I can't seem to find a way to set it on a package level...

Answer 1

You should set the package name as logger-name

// Sets the package level to INFO LoggerContext loggerContext = (LoggerContext)LoggerFactory.getILoggerFactory(); Logger rootLogger = loggerContext.getLogger("com.somepackage"); rootLogger.setLevel(Level.INFO); 

You should be able to get the package name more elegant, but this is basically it. This follows the tree like hierarchy for the Logger Context: Logger Context

Answer 2

You can do it by using logback..

Logger LOG = (Logger) org.slf4j.LoggerFactory.getLogger(ch.qos.logback.classic.Logger.ROOT_LOGGER_NAME); LOG.setLevel(Level.WARN); 

This solved my problem.
