xml/注解方式定义的消费服务bean如何配合@Conditional相关注解

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？

No source file or test is named. Start by tracing registerBD and the condition-annotation bean-definition scan with the shown @ConditionalOnMissingBean case, then reproduce the XML/annotation-defined service using a generic ReferenceBean; done means the condition matches the intended bean despite the generic RootBD.
