spring bean的生命周期，以及九大后置处理器

BeanPostProcessor#postProcessBeforeInitialization

给对象赋值

DefaultListableBeanFactory#resolveDependency

SmartInstantiationAwareBeanPostProcessor#determineCandidateConstructors

SmartInitializingSingleton

AbstractAutowireCapableBeanFactory#autowireConstructor

通过构造器生成对象（使用策略模式）

AbstractApplicationContext#finishBeanFactoryInitialization

AbstractAutowireCapableBeanFactory#resolveBeforeInstantiation

BeanPostProcessor#postProcessAfterInitialization

ApplicationListener#onApplicationEvent

默认set注入

AbstractBeanFactory#resolveBeanClass

构造注入

调用对象的初始化方法

InstantiationAwareBeanPostProcessor#postProcessAfterInstantiation

AbstractAutowireCapableBeanFactory#createBeanInstance

BeanFactory#getBean(java.lang.String)

AbstractAutowireCapableBeanFactory#instantiateUsingFactoryMethod

Ribben的实现方式，kafkaspring的实现方式

DependencyDescriptor#resolveCandidate

ConstructorResolver#autowireConstructor

AutowireCandidateResolver#getSuggestedValue

复制处理bean定义信息中的beanClass属性的值

拦截@bean的形式的生成BeanMethodInterceptor，ConfigurationClassPostProcessor#postProcessBeanFactory添加上的，通过对字节码增强技术对@Configer类的方法添加拦截，类似aop

AbstractApplicationContext#refresh

AbstractAutowireCapableBeanFactory#invokeAwareMethods

ConstructorResolver#createArgumentArray

这是对实体bean的一些处理，

Eureka服务端启动的方式

AbstractApplicationContext#finishRefreshfinishRefresh

Nacos服务注册与发现的实现

AbstractAutowireCapableBeanFactory#populateBean

AbstractAutowireCapableBeanFactory#getEarlyBeanReference

实体对象的前置处理器

从容器中拿依赖的对象

AbstractAutowireCapableBeanFactory#doCreateBean

AbstractAutowireCapableBeanFactory#invokeInitMethods

getBean

MergedBeanDefinitionPostProcessor#postProcessMergedBeanDefinition

InstantiationAwareBeanPostProcessor#postProcessBeforeInstantiation

处理通过@Bean或者通过BeanFactory方式注入的bean

省略部分

@Resouce   CommonAnnotationBeanPostProcessor#postProcessPropertyValues

获取已经生成好的对象

放入早期对象的引用到三级缓存中去(这里可以是代理对象或者是普通对象)

InitDestroyAnnotationBeanPostProcessor，CommonAnnotationBeanPostProcessor，AutowiredAnnotationBeanPostProcessor

ConfigurationClassEnhancer.BeanMethodInterceptor#intercept

DefaultListableBeanFactory#doResolveDependency

调用bean的后置处理器对象

InstantiationStrategy#instantiate

Lifecycle#start

ConstructorResolver#resolveAutowiredArgument

InstantiationAwareBeanPostProcessor#postProcessPropertyValues
