Example 2

        // 创建 BeanFactory 容器
        AnnotationConfigApplicationContext applicationContext = new AnnotationConfigApplicationContext();
        // 将当前类 ObjectProviderDemo 作为配置类(Configuration Class)
        applicationContext.register(ObjectProviderDemo.class);

        // 1. 获取 HierarchicalBeanFactory <- ConfigurableBeanFactory <- ConfigurableListableBeanFactory
        ConfigurableListableBeanFactory beanFactory = applicationContext.getBeanFactory();
//        System.out.println("当前 BeanFactory 的 Parent BeanFactory : " + beanFactory.getParentBeanFactory());

        // 2. 设置 Parent BeanFactory
        HierarchicalBeanFactory parentBeanFactory = createParentBeanFactory();
        beanFactory.setParentBeanFactory(parentBeanFactory);
//        System.out.println("当前 BeanFactory 的 Parent BeanFactory : " + beanFactory.getParentBeanFactory());

        displayContainsLocalBean(beanFactory, "user");
        displayContainsLocalBean(parentBeanFactory, "user");

        displayContainsBean(beanFactory, "user");

        // 启动应用上下文
        applicationContext.refresh();

        // 关闭应用上下文
        applicationContext.close();
