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...

答案 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

答案 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.
