Spring Bean生命周期

实现BeanNameAware接口调用setBeanName 

invokeAwareMethods

调用Aware接口方法

实现InitializingBean接口调用afterPropertiesSet

4.Bean调用

2.设置Bean属性

图例

3.初始化回调

源码位置AbstractAutowireCapableBeanFactory#initializeBean

populateBean()

调用BeanPostProcessor的postProcessBeforeInitialization

执行自定义初始化方法init-method

执行自定义销毁方法destroy-method

实现BeanFactoryAware接口调用setBeanFactory

5.销毁Bean

1.构造Bean对象

initializeBean()

开始

createBeanInstance()

applyBeanPostProcessorsBeforeInitialization

实现DisposableBean接口调用destroy

invokeInitMethods

结束

applyBeanPostProcessorsAfterInitialization

源码位置AbstractAutowireCapableBeanFactory#doCreateBean

执行初始化方法

调用BeanPostProcessor的postProcessAfterInitialization

实现BeanClassLoaderAware接口调用setBeanClassLoader
