Logging springboot application with log4j

Question

In my java application, I am using maven and springboot, log4j for logging. The problem is logging. The log4j does not have anymore logging control after starting up the springboot(SpringApplication.run(Starter.class);). Please see the main() below. After starting the springboot it obeys to logging.level.*. in the properties file. Not sure what I am doing wrong.

public static void main(String[] args) {
    logger.info("started"); //It logs this with log4j
    SpringApplication.run(Starter.class);
    logger.info("started");//but it does not log this. 
}

you can exclude the Logback from spring boot dependency. see [enter link description here](https://stackoverflow.com/questions/23984009/disable-logback-in-springboot) — Mahmoud Murad, Dec 15 '18 at 06:32

 <Loggers>
    <AsyncRoot level="DEBUG" includeLocation="true">
        <AppenderRef ref="prodLog" level="INFO"/>
        <AppenderRef ref="STDOUT" level="WARN"/>
    </AsyncRoot>
