public void setDetectHandlersInAncestorContexts(boolean detectHandlersInAncestorContexts)
Default is "false": Only handler beans in the current ApplicationContext will be detected, i.e. only in the context that this HandlerMapping itself is defined in (typically the current DispatcherServlet's context).
Switch this flag on to detect handler beans in ancestor contexts (typically the Spring root WebApplicationContext) as well.

protected void detectHandlers() throws BeansException
The actual URL determination for a handler is up to the concrete
determineUrlsForHandler(String)
implementation. A bean for
which no such URLs could be determined is simply not considered a handler.
