How to get callback when Spring web aplication is finished starting

Question

I have some action I need to perform after the entire spring application has finished loading. The action must happen after all beans are inititlized and all controllers can start serving requests.

I tried implementing a ServletContextListener and adding it as a listener in AbstractAnnotationConfigDispatcherServletInitializer but this happens as soon as the application boot up and not after. Also I am not using SpringBoot avaiable to do this.

Thanks,

Because you are using spring mvc.

So RequestHandledEvent will fulfill your requirement.

RequestHandledEvent

This is a web-specific event telling all beans that an HTTP request has been serviced.
