Spring生命周期

开始初始化容器

AbstractApplicationContext

invokeBeanFactoryPostProcessors(beanFactory); //会调用postProcessBeanFactory()方法

        ApplicationContext xmlAppContext = new ClassPathXmlApplicationContext(\"beans.xml\"); 

只有PersonBean才会调用到这里(Bean级别的)

applyBeanPostProcessorsBeforeInitialization();

参考类

生成BeanDefinition缓存起来

BeanFactory处理和注册BenaPostProcess

preInstantiateSingletons(){  for(beanName : beanNames)  {    getBean(beanName);  }}

DefaultSingletonBeanRegistry{     singletonObject;     singleTonFactories;     earlySingleTonObjects;     protected void addSingleton();}

destroy(); //DisposibleBean接口方法

PersonBeanMyBeanDefinitionRegistryPostProcessor

PersonBean.class

postProcessBeanFactory(beanFactory);    

initializeBean();

createBean

finishBeanFactoryInitialization

DefaultListableBeanFactory implements BeanDefinitionRegistry{      beanDefinitionMap;      beanDefinitionNames;      registerBeanDefinition();}

//ConfigurationClassPostProcessor.javainvokeBeanDefinitionRegistryPostProcessors{     （ConfigurationClassPostProcessor）BeanDefinitionRegistryPostProcessor.postProcessBeanDefinitionRegistry();}

DefaultListableBeanFactory.registerBeanDefinition();

addsingleton()

//ConfigurationClassPostProcessor 进来后调用的ImportSelector.selectImports();ImportBeanDefinitionRegistrar.registerBeanDefinitions();//@Bean对应的BeanDefinition也是在这里被处理的参考

applyBeanPostProcessorsAfterInitialization();

 registerBeanPostProcessors(beanFactory);  //getBean(beanPostProcessor)

xmlAppContext).registerShutdownHook()

destoryBean

AbstractAutowireCapableBeanFactory

invokeAwareMethods();  //BeanFactoryAware

invokeInitMethods();   //InitializingBean.afterPropertiesSet();

populateBean();

所有Bean都要走一遍(容器级别的)
