bean中拿到ApplicationContext对象

	public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
		if (bean instanceof ResourceLoaderAware) {
			((ResourceLoaderAware) bean).setResourceLoader(this.applicationContext);
		}
		if (bean instanceof ApplicationEventPublisherAware) {
			((ApplicationEventPublisherAware) bean).setApplicationEventPublisher(this.applicationContext);
		}
		if (bean instanceof MessageSourceAware) {
			((MessageSourceAware) bean).setMessageSource(this.applicationContext);
		}
		if (bean instanceof ApplicationContextAware) {
			((ApplicationContextAware) bean).setApplicationContext(this.applicationContext);
		}
		return bean;
	}

这个方法是定义在ApplicationContextAwareProcessor中的，一般都会注入到BeanFactory中。
从上面可以看出想要拿到ApplicationContext的方法就比较多了，看需要吧。
