Does spring have a way to load things when the application loads first? Globally

Question

Is there any spring way in initializing when loading MVC?

Let's say I need to create global objects based on configuration files, is there a place for this or just create my own servlet and do it in oninit?

Answer 1

How about a standard one @PostConstruct?

@Service
class AnySpringBean {

    @PostConstruct
    public void init() {
        //run when bean is created
    }

}

Also works with @Controller.

UPDATE: ContextLoaderListener) contextInitialized() web.xml (. user1076371 answer). , Spring bean.
