如果把CustomizedBeanDefinitionRegistryPostProcessor标记为@Configuration，会报如下警告。
信息: Cannot enhance @Configuration bean definition ‘customizedBeanDefinitionRegistryPostProcessor’ since its singleton instance has been created too early. The typical cause is a non-static @Bean method with a BeanDefinitionRegistryPostProcessor return type: Consider declaring such methods as ‘static’.

如果把标记改为@Component就不会有这个问题。
请问这个警告是为啥会出现？为什么看视频里您的环境没有提示这个警告？
