Spring Context启动时打印应用程序横幅

Question

I'm trying to implement an application Banner that prints the version and other information when our application starts. I have tried implementing SmartLifecycle and ApplicationListener without success.

The callback method never gets called and the banner never prints. What am I doing wrong?

public class Banner implements ApplicationListener<ContextStartedEvent>
{
    private static final Logger log = LoggerFactory.getLogger(Banner.class);

    @Override
    public void onApplicationEvent(ContextStartedEvent event)
    {
        log.info("*******************************************************");
        log.info("Application v1.8 starting");
        log.info("*******************************************************");
    }
}

ContextStartedEvent is raised only when ConfigurableApplicationContext.start() method is invoked. Use ContextRefreshedEvent instead of ContextStartedEvent

If you use spring-boot, the below solution will work for you.

Use ASCII art generator OR Use Spring Boot Banner Generator ; If you want to use any "image" to generate a banner for your Spring Boot application.

Copy the generated ASCII characters into /src/main/resources/banner.txt

Start the spring-boot application.
