Description

如题，在@ConditionalOnBean/@ConditionalOnMissingBean下：

@ConditionalOnMissingBean(value = UserService.class, parameterizedContainer = {ReferenceBean.class})

失效，在Condition相关注解扫描beanDefination时，获取的RootBD是Reference<?>，导致不能匹配，是否在registerBD时，未考虑泛型问题？

Contributor guide

Research direction
Investigate how ReferenceBean is registered as a bean definition and whether generic type information is preserved when scanning for @Conditional annotations. Check the BeanDefinitionRegistryPostProcessor or similar that processes @Reference and ensure the root bean definition type is correctly set to the parameterized type of ReferenceBean.
