       Bean factory implementations should support the standard bean lifecycle interfaces as far as possible. The full set of initialization methods and their standard order is:
       1. BeanNameAware's setBeanName
       2. BeanClassLoaderAware's setBeanClassLoader
       3. BeanFactoryAware's setBeanFactory
       4. ResourceLoaderAware's setResourceLoader (only applicable when running in an application context)
       5. ApplicationEventPublisherAware's setApplicationEventPublisher (only applicable when running in an application context)
       6. MessageSourceAware's setMessageSource (only applicable when running in an application context)
       7. ApplicationContextAware's setApplicationContext (only applicable when running in an application context)
       8. ServletContextAware's setServletContext (only applicable when running in a web application context)
       9. postProcessBeforeInitialization methods of BeanPostProcessors
       10. InitializingBean's afterPropertiesSet
       11. a custom init-method definition
       12. postProcessAfterInitialization methods of BeanPostProcessors

       On shutdown of a bean factory, the following lifecycle methods apply:
       1. DisposableBean's destroy
       2. a custom destroy-method definition
