Java – logger slf4j does not have the level configured with logback

My log record is through logback Configuration of logback using groovy files

Now, when my Maven POM project aggregates all other projects, it passes all system properties to set the correct logging level

However, when JUnit test runs, for some reasons, the logger will not receive the correct level even if the test class static @ beforeclass ensures that the log configuration is correct

The loggers in the test are not a problem, and - and so are - they - the real problem is that the loggers running code segments (my program loggers are everywhere) are set to the wrong logging level When the configurator tests, they do not receive logging

However, use logback The project report is correct when logback initialization is performed on the goovy file However, the actual record level is set to trace or all

From the output below, it is obvious that logback is configured as info However, the first item log record in trace (the last line) indicates that it has not been extracted

Please help me.

Solution

I have a similar problem

import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.Logger;
import org.slf4j.LoggerFactory;
...
static Logger logger;
static{
   // Logger.ROOT_LOGGER_NAME == "ROOT"
   logger = ((Logger) LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME));
   logger.setLevel(Level.INFO);
}

…

I think in your case, somehow, a library uses its own consoleprovider instance with a name other than "stdout" I hope setting the root log level can solve the problem

root(loglevel,['ROOT']);
