SpringMVc source code learning

In the parent class FrameworkServlet of DispatcherServlet, there is a piece of code:

public void onApplicationEvent(ContextRefreshedEvent event) {
		this.refreshEventReceived = true;
		onRefresh(event.getApplicationContext());
	}

@Override
	protected void onRefresh(ApplicationContext context) {
		initStrategies(context);
	}

	/**
	 * Initialize the strategy objects that this servlet uses.
	 * <p>May be overridden in subclasses in order to initialize further strategy objects.
	 */
	protected void initStrategies(ApplicationContext context) {
		initMultipartResolver(context);
		initLocaleResolver(context);
		initThemeResolver(context);
		initHandlerMappings(context);
		initHandlerAdapters(context);
		initHandlerExceptionResolvers(context);
		initRequestToViewNameTranslator(context);
		initViewResolvers(context);
		initFlashMapManager(context);
	}

 Here, the refresh event of the spring container is monitored, which will be called in the publish event in the abstartappcontionContext class, the onrefresh method is called, the springmvc is initialized, a policy is loaded, and some classes are created. If not specified, the default class is taken.
