Can I configure startup and shutdown logs for Spring Boot applications?

Question

For the ability to verify the startup and shutdown of our Spring Boot applications we want to configure a startup.log and shutdown.log capturing events that bootstrap and shutdown the application.

For startup everything up to:

Root WebApplicationContext: initialization completed in {x} ms

And for shutdown everything from:

Closing org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext@53bd8fca: startup date [Wed Aug 19 09:47:10 PDT 2015]; root of context hierarchy

to the end.

Is this something that is container specific? (Tomcat vs Jetty vs Undertow)

Answer 1

You can create an event listener that watches for ApplicationReadyEvent and ContextStoppedEvent and log whatever you want.

@Service
public class Foo {

    @EventListener
    public void onStartup(ApplicationReadyEvent event) { ... }

    @EventListener
    public void onShutdown(ContextStoppedEvent event) { .... }

}
