String IOC初始化过程

k:beanNamev：BeanDefinition

destroyMethod

BeanPostProcessor.postProcessAfterInitialization

put一级缓存

可直接返回bean停止创AOP切面建

1.InstantiationAwareBeanPostProcessor

3.MergedBeanDefinitionPostProcessor

determineCandidateConstructors

6.InstantiationAwareBeanPostProcessor

BeanDefinitionScanner

初始化后创建AOP代理

实例化

5.InstantiationAwareBeanPostProcessor

BeanDefinitionRegister

BeanFactoryPostProcessor：在BeanFactory标准初始化之后调用，来定制和修改BeanFactory的内容。BeanDefinitionRegisterPostProcessor：在所有bean定义信息将要被加载，bean实例还未创建的时候加载，优先于BeanFactoryPostProcessor执行，利用BeanDefinitionRegistryPostProcessor给容器中再额外添加一些组件

getBean(\"beanName\")

beanClassName

requireDistrction

BeanPostProcessor.postProcessBeforeInitialization

BeanPostProcessor

BeanDefinitionReader

BeanDefinition

JDK动态代理

postProcessBeforeInitialization

getEarlyBeanReference

8.BeanPostProcessor

资源文件定位

Spring是如何将自己写的@Compment或者XML中的 bean初始化成bean？

2.SmartInstantiationAwareBeanPostProcessor

FileSystemXmlApplicationContext

bean的9大后置处理器

getBean

postProcessBeforeInstantiation

bean的生命周期

初始化前调用@PostContruct

终止赋值

postProcessAfterInitialization

ClassPathXmlApplicationContext

postProcessMergedBeanDefinition

指定实例化的构造函数

解析

注册BeanDefinitionMap

scope

initMethodName

initMethod

isSingleton

解决循环引用AOP

Bean

@Autowired @Value预解析

属性填充

lazzyInit

BeanDefinitionRegisterPostProcessor

CGLIB

注入属性PropertyValues

4.SmartInstantiationAwareBeanPostProcessor

AnnotationConfigApplicationContext
