Logs not showing for spring application - spring-boot

Question

I am using slf4j logger in my application. But I don't the see the logs in the console
This is my application class
#SpringBootApplication
public class InternalReplacerServiceApplication {
public static void main(String[] args) {
SpringApplication.run(InternalReplacerServiceApplication.class, args);
Logger LOG = LoggerFactory.getLogger(InternalReplacerServiceApplication.class);
LOG.debug("inside app");
}
}
When I run the app these are the logs I see

Answer 1

As Dirk mentioned, the default level is INFO.
You can enable debug for a logger in application.properties:
logging.level.com.example=debug
Where com.example is the name of the logger.
