2.Specified by: setBeanClassLoader(...) in BeanClassLoaderAware
3.Specified by: setBeanFactory(...) in BeanFactoryAware
4.Specified by: setApplicationContext(...) in ApplicationContextAware
5.Specified by: afterPropertiesSet() in InitializingBean
6.Specified by: postProcessBeanDefinitionRegistry(...) in BeanDefinitionRegistryPostProcessor
7.Specified by: postProcessBeanFactory(...) in BeanFactoryPostProcessor
