调用流程

  1. 创建Environment（StandardEnvironment）
  2. 创建BeanFactory（DefaultListableBeanFactory）
  3. 注册BeanPostProcessor以及注册环境的Bean
  4. 执行基础的BeanDefinitionRegistryPostProcessor#postProcessBeanDefinitionRegistry
  5. 排序自定义BeanDefinitionRegistryPostProcessor，PriorityOrdered这个优先级先排
  6. 执行的BeanDefinitionRegistryPostProcessor#postProcessBeanDefinitionRegistry
  7. 排序自定义BeanDefinitionRegistryPostProcessor，Ordered这个优先级
  8. 执行的BeanDefinitionRegistryPostProcessor#postProcessBeanDefinitionRegistry
  9. 排序其他自定义BeanDefinitionRegistryPostProcessor
  10. 执行的BeanDefinitionRegistryPostProcessor#postProcessBeanDefinitionRegistry
  11. 执行自定义的BeanDefinitionRegistryPostProcessor#postProcessBeanFactory
  12. 执行基础的BeanDefinitionRegistryPostProcessor#postProcessBeanFactory
  13. 根据PriorityOrdered、Ordered排序以及其他执行BeanFactoryPostProcessor#postProcessBeanFactory
  14. 根据PriorityOrdered、Ordered排序以及其他注册BeanPostProcessor
  15. 根据PriorityOrdered、Ordered排序以及其他注册MergedBeanDefinitionPostProcessor
