SpringBoot How to log in ApplicationListener of ApplicationStartingEvent?

public class MyTestListener implements ApplicationListener<ApplicationStartingEvent> {

    private static final Logger logger = LoggerFactory.getLogger(MyTestListener.class);

    @Override
    public void onApplicationEvent(ApplicationStartingEvent event) {
        logger.info("MyTestListener run.....");

        //todo--my logic
    }
}

I have a listener named MyTestListener. It seems that 'logger.info("MyTestListener run.....");' will not log .

MyEnv:

spring boot: 2.5.9
logback: 1.2.3

You can't easily do so as the logging system isn't fully initialized until the ApplicationEnvironmentPreparedEvent has been published. Until that time, logging is suppressed. If you really want to log in your listener, you may be able to use a org.springframework.boot.logging.DeferredLog that you replay later on.
