refreshContext断点如何执行

    public void refresh() throws BeansException, IllegalStateException {
        synchronized (this.startupShutdownMonitor) {
            // Prepare this context for refreshing.
            prepareRefresh();
 
            // Tell the subclass to refresh the internal bean factory.
            ConfigurableListableBeanFactory beanFactory = obtainFreshBeanFactory();
 
            // Prepare the bean factory for use in this context.
            prepareBeanFactory(beanFactory);
 
            try {
                // Allows post-processing of the bean factory in context subclasses.
                postProcessBeanFactory(beanFactory);
 
                // Invoke factory processors registered as beans in the context.
                invokeBeanFactoryPostProcessors(beanFactory);
 
                // Register bean processors that intercept bean creation.
                registerBeanPostProcessors(beanFactory);
 
                // Initialize message source for this context.
                initMessageSource();
 
                // Initialize event multicaster for this context.
                initApplicationEventMulticaster();
 
                // Initialize other special beans in specific context subclasses.
                onRefresh();
 
                // Check for listener beans and register them.
                registerListeners();
 
                // Instantiate all remaining (non-lazy-init) singletons.
                finishBeanFactoryInitialization(beanFactory);
 
                // Last step: publish corresponding event.
                finishRefresh();
            }
