ConfigurableListableBeanFactory 提供bean definition的解析,注冊功能,再對單例來個預加載(解決循環依賴問題).

貌似我們一般開發就會直接定義這么個接口了事.而不是像Spring這樣先根據使用情況細分那么多,到這邊再合并
ConfigurableListableBeanFactory具體：

1、2個忽略自動裝配的的方法。

2、1個注冊一個可分解依賴的方法。

3、1個判斷指定的Bean是否有資格作為自動裝配的候選者的方法。

4、1個根據指定bean名，返回注冊的Bean定義的方法。

5、2個凍結所有的Bean配置相關的方法。

6、1個使所有的非延遲加載的單例類都實例化的方法。

總結：工廠接口ConfigurableListableBeanFactory同時繼承了3個接口，ListableBeanFactory、AutowireCapableBeanFactory 和 ConfigurableBeanFactory，擴展之后，加上自有的這8個方法，這個工廠接口總共有83個方法，實在是巨大到不行了。這個工廠接口的自有方法總體上只是對父類接口功能的補充，包含了BeanFactory體系目前的所有方法，可以說是接口的集大成者。
