Spring源码情操陶冶-AbstractApplicationContext#finishRefresh

承接前文Spring源码情操陶冶-AbstractApplicationContext#finishBeanFactoryInitialization

约定web.xml配置的contextClass为默认值XmlWebApplicationContext

直接源码AbstractApplicationContext#finishRefresh

	/**
	 * Finish the refresh of this context, invoking the LifecycleProcessor's
	 * onRefresh() method and publishing the
	 * {@link org.springframework.context.event.ContextRefreshedEvent}.
	 */
	protected void finishRefresh() {
		// Initialize lifecycle processor for this context.
		//会找寻lifecycleProcessor对应的bean，否则默认采用DefaultLifecycleProcessor
		initLifecycleProcessor();

		// Propagate refresh to lifecycle processor first.
		getLifecycleProcessor().onRefresh();

		// Publish the final event.
		//其实是执行ContextRefreshedEvent该事件是针对spring mvc来的
		publishEvent(new ContextRefreshedEvent(this));

		// Participate in LiveBeansView MBean, if active.
		LiveBeansView.registerApplicationContext(this);
	}

从注释上可以得知其是完成对context的刷新，并执行LifecycleProcessor的onRefresh()方法和执行相关的ContextRefreshedEvent事件，但可惜引导DispatcherServlet进行初始化的ContextRefreshListener并不是由spring来触发的，而是由tomcat加载web.xml中的spring mvc配置文件启动的

DispatcherServlet#initStrategies

我们简单看下此段代码，spring启动只会帮助springmvc先初始化默认的策略方案，其他则由springmvc本身来执行，具体如下

	/**
	 * 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);
	}

关于spring mvc的初始化操作，我们放在后续计划中讨论，本文便不再继续深究
