貌似我们一般开发就会直接定义这么个接口了事.而不是像Spring这样先根据使用情况细分那么多,到这边再合并 ConfigurableListableBeanFactory具体
1、2个忽略自动装配的的方法。
2、1个注册一个可分解依赖的方法。
3、1个判断指定的Bean是否有资格作为自动装配的候选者的方法。
4、1个根据指定bean名返回注册的Bean定义的方法。
5、2个冻结所有的Bean配置相关的方法。
6、1个使所有的非延迟加载的单例类都实例化的方法。
总结工厂接口ConfigurableListableBeanFactory同时继承了3个接口ListableBeanFactory、AutowireCapableBeanFactory 和 ConfigurableBeanFactory扩展之后加上自有的这8个方法这个工厂接口总共有83个方法实在是巨大到不行了。这个工厂接口的自有方法总体上只是对父类接口功能的补充包含了BeanFactory体系目前的所有方法可以说是接口的集大成者。
