总结：

【Bean工厂后置处理器】**容器初始化之后操作**【BeanFactoryPostProcessor】

【实例化Bean后置处理器】**容器中对所有Bean进行实例化时的一个操作**【InstantiationAwareBeanPostProcessorAdapter】

【构造器】

【SET注入】

【<bean>的init-method】

【统一处理器】**容器中对所有Bean进行初始化时的一个操作**【BeanPostProcessor】

**Bean初始化阶段    **

**Spring容器初始化bean大致过程**

**定义bean标签 **> **将bean标签解析成BeanDefinition** > **调用构造方法实例化(IOC)** >  **属性值得依赖注入初始化(DI) **

**Bean的作用域 **
