Mixing Java Logging Levels

Question

I set the logging level to CONFIG, but cannot see the messages written at the CONFIG level. What am I missing?

Configuration:

Logger logger = java.util.logging.Logger.getLogger("xxx");
logger.setLevel(java.util.logging.Level.CONFIG);

Tests:

logger.log(java.util.logging.Level.SEVERE, "severe");
logger.log(java.util.logging.Level.WARNING, "warning");
logger.log(java.util.logging.Level.INFO, "info");
logger.log(java.util.logging.Level.CONFIG, "config");
logger.log(java.util.logging.Level.FINE, "fine");
logger.log(java.util.logging.Level.FINER, "finer");
logger.log(java.util.logging.Level.FINEST, "finest");

Conclusion:

SEVERE: severe
WARNING: warning
INFO: info

Answer 1

I usually use logback to implement logging, which seems a little better documented. Therefore, I would recommend switching to this.

But to answer your question, I think what happens is that your Loggerset up correctly, but Handlerit sends its messages. The default configuration probably attaches a INFOlayer protocol handler to the root log.

for (Handler handler : Logger.getLogger("").getHandlers()) {
    handler.setLevel(Level.CONFIG);
}
logger.config("config");
