ClassPathXmlApplicationContext

ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring.xml");

追溯发现其实继承了ApplicationContext

 继承关系

public interface ApplicationContext extends EnvironmentCapable, ListableBeanFactory, HierarchicalBeanFactory, MessageSource, ApplicationEventPublisher, ResourcePatternResolver {

发现继承了很多beanfactory，而这些beanfactory都继承于beanfactory

ApplicationContext是一个集大成者
