Research direction

Investigate the ReferenceAnnotationBeanPostProcessor class in the Dubbo source code to understand how aliases are registered for @DubboReference beans. Compare the behavior with Dubbo 2.x to identify the change. The goal is to allow different bean types to be injected with the same property name without causing BeanNotOfRequiredTypeException. Consider implementing a unique alias strategy or leveraging Spring's type based injection. Review the linked issue #10443 and any related PRs or comments for additional context.
