That looks mostly right, although in the code I've seen, the
initializers are invoked just before the refresh(). So after any config
resource loading, etc.

To be clear, you shouldn't have to actually write any code like this, at
least for the root web app context or Spring MVC dispatcher servlet
context.  You just declare the initializer in web.xml, and the Spring
ServletContextListener (ContextLoaderListener) does the rest.
