ConfigurableListableBeanFactory

ConfigurableListableBeanFactory 提供bean definition的解析,注册功能,再对单例来个预加载(解决循环依赖问题).

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。
