Is there a way to have spring run additional code at application startup failure?

We have a spring web-application running on a Tomcat server that we would like to have some additional code run ONLY if there is an issue with the webapp's startup.

However, any errors we receive will come from either Bean Creation Issues (which, hopefully we would catch before ever releasing) or a Flyway upgrade script issue. Both cases, the exceptions are caught within the spring core somewhere, and I'd like to run some additional code in those situations before the webapp failure finishes. I'm not 100% sure how to set this up though, considering where the exceptions are thrown.

I've been looking at Spring's Life Cycle configuration annotations, and while I have considered running the code in the @PreDestroy method we're providing, that means it would run our code every time we restarted the webapp, instead of just on startup failures. Is there a way to indicate the differences between a normal shutdown and a failed startup using the life cycle annotations?

You could register your own ServletContextListener instead of the Spring's one and delegate contextInitialized method invocation to the Spring implementation you use for loading Spring context (whichever one you use, for example org.springframework.web.context.ContextLoaderListener).

Then catch and handle the desired exceptions.
