02_获取bean工厂

查看全部
// Tell the subclass to refresh the internal bean factory. ConfigurableListableBeanFactory beanFactory = obtainFreshBeanFactory();

1. 刷新【创建】bean工厂

refreshBeanFactory();

• 只是给bean工厂设置了序列号
• 而beanFactory是GenericApplicationContext构造器中就创建好的 this.beanFactory = new DefaultListableBeanFactory();

2. 将上面的beanFactory返回出去

ConfigurableListableBeanFactory beanFactory = getBeanFactory();
