BeanDefinition源码解析

Posted 2020-10-13 insaneXs

我们知道BeanDefintion定义了Bean在IoC容器内的基本数据结构。在学习IoC之前先了解BeanDefition对我们理解IoC容器是有帮助的。

 

首先BeanDefinition是一个接口，继承了AttributeAccessor和BeanMetadataElement。

我们主要来学习下他的一个实现类，AbstractBeanDefinition。

这虽然是一个抽象类，但是提供了BeanDefinition接口的全部实现。是一个基本的框架。其子类有RootBeanDefinition（表示父级），ChildBeanDefinition（表示子级）和GenericBeanDefinition（一般的BeanDefinition实现）。

 

来看代码：
