加入 spring-cloud-starter-dubbo-2021.0.1.0在gateway上运行，显示循环依赖

The dependencies of some of the beans in the application context form a cycle:

targeterBeanPostProcessor defined in class path resource [com/alibaba/cloud/dubbo/autoconfigure/DubboOpenFeignAutoConfiguration.class]
↓
com.alibaba.cloud.dubbo.metadata.repository.DubboServiceMetadataRepository (field private com.alibaba.cloud.dubbo.service.DubboMetadataServiceProxy com.alibaba.cloud.dubbo.metadata.repository.DubboServiceMetadataRepository.dubboMetadataConfigServiceProxy)
↓
com.alibaba.cloud.dubbo.service.DubboMetadataServiceProxy
┌─────┐
| com.alibaba.cloud.dubbo.autoconfigure.DubboMetadataAutoConfiguration (field private com.alibaba.cloud.dubbo.metadata.resolver.MetadataResolver com.alibaba.cloud.dubbo.autoconfigure.DubboMetadataAutoConfiguration.metadataResolver)
└─────┘

Reproduce the circular-dependency failure with spring-cloud-starter-dubbo-2021.0.1.0 on the gateway. Start with DubboOpenFeignAutoConfiguration, DubboServiceMetadataRepository, DubboMetadataServiceProxy, and DubboMetadataAutoConfiguration, then trace the dependency cycle shown in the report. Done means the gateway starts without this cycle.
