1 PostProcessorRegistrationDelegate 类简介 PostProcessorRegistrationDelegate 是一个静态工具类,包访问权限,AbstractApplicationContext's

SpringBoot启动的时候 按照链路执行到方法 AbstractApplicationContext -> refresh ->invokeBeanFactoryPostProcessors -> PostProcessorRegistrationDelegate...ConfigurationClassPostProcessor#processConfigBeanDefinitions->ImportBeanDefinitionRegistrar#registerBeanDefinitions /** PostProcessorRegistrationDelegate
AbstractApplicationContext#refresh -> 2.激活各种BeanFactory处理器： invokeBeanFactoryPostProcessors -> 3.循环扫描bean定义：PostProcessorRegistrationDelegate...#invokeBeanFactoryPostProcessors -> 4.调用bean定义注册处理器：PostProcessorRegistrationDelegate#invokeBeanDefinitionRegistryPostProcessors

AbstractApplicationContext#refresh()方法 相信大家已经比较熟悉了 进入invokeBeanFactoryPostProcessors()调用BeanFactory后置处理器方法 进入PostProcessorRegistrationDelegate...juejin/drink 那么此方法会递归调用扫描com/juejin/drink下的所有类和目录 如果是需要注册的bean 那么放入new的LinkedHashSet中返回 经过如上步骤 程序会返回到PostProcessorRegistrationDelegate

而InitializingBean和DisposableBean接口是针对单个bean的 springboot refresh 各种post processor 在refresh中调用了PostProcessorRegistrationDelegate.invokeBeanFactoryPostProcessors...PostProcessorRegistrationDelegate是AbstractApplicationContext委托执行post processors任务的工具类。
beanName) throws BeansException; } 调用逻辑 AbstractAutowireCapableBeanFactory.initializeBean 注册逻辑 PostProcessorRegistrationDelegate.registerBeanPostProcessors...调用逻辑： AbstractApplicationContext.refresh() AbstractApplicationContext.invokeBeanFactoryPostProcessors PostProcessorRegistrationDelegate.invokeBeanFactoryPostProcessors
this.beanFactoryPostProcessors; // 这些是直接注册到上下文中的BeanFactoryPostProcessor } 这里其实主要分为两部分逻辑： 借助后处理器委托类 PostProcessorRegistrationDelegate...1、后置处理委托类 这里又出现了一个新类 PostProcessorRegistrationDelegate，该类实际上是一个静态工具类，专门提供静态方法以用于处理上下文的后处理操作的，该类总共提供了两个方法...该方法用于对 BeanFactory 进行后置处理； registerBeanPostProcessors()：该方法用于向上下文中注册 Bean 的后置处理器； 2、对BeanFactory进行后置处理 PostProcessorRegistrationDelegate.invokeBeanFactoryPostProcessors...这一步与调用 BeanFactory 一样，都通过后置处理委托类 PostProcessorRegistrationDelegate 进行： protected void registerBeanPostProcessors...(ConfigurableListableBeanFactory beanFactory) { PostProcessorRegistrationDelegate.registerBeanPostProcessors
