Question

在我的Java应用程序中，我正在使用maven和springboot, log4j进行日志记录。问题是记录。启动log4j之后，springboot(SpringApplication.run(Starter.class);)不再具有日志记录控制。请参阅下面的main()。启动springboot后，它遵循属性文件中的logging.level.*.。不知道我在做什么错。

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. 
}

感谢您的回答。

更改下面的线条效果很好。

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