Spring Context继承关系
ClassPathXmlApplicationContext->AbstractXmlApplicationContext->AbstractRefreshableConfigApplicationContext->AbstractRefreshableApplicationContext
->AbstractApplicationContext
而AbstractRefreshableApplicationContext 包含DefaultListableBeanFactory beanFactory
DefaultListableBeanFactory->AbstractAutowireCapableBeanFactory->AbstractBeanFactory->FactoryBeanRegistrySupport->DefaultSingletonBeanRegistry
AbstractBeanFactory有如下元素
final Map<String, RootBeanDefinition> mergedBeanDefinitions=new ConcurrentHashMap<String, RootBeanDefinition>(64);
final List<BeanPostProcessor> beanPostProcessors = new ArrayList<BeanPostProcessor>();
boolean hasInstantiationAwareBeanPostProcessors;
1)[ClassPathXmlApplicationContext] ClassPathXmlApplicationContext(String configLocation)
this(new String[] {configLocation}, true, null);
2)[ClassPathXmlApplicationContext] ClassPathXmlApplicationContext(String[] configLocations, boolean refresh, ApplicationContext parent)
if (refresh) { refresh(); }
3)[AbstractApplicationContext] refresh()
ConfigurableListableBeanFactory beanFactory=obtainFreshBeanFactory();//解析Xml组装eanDefinition
...
invokeBeanFactoryPostProcessors(beanFactory);
registerBeanPostProcessors(beanFactory);//注册BeanPostProcessors.
...
finishBeanFactoryInitialization(beanFactory);//根据BeanDefinition初始化Bean
