解决spring boot 2.6.4版本循环依赖问题

引用spring boot 2.6.4 版本 报循环依赖错误

***************************
APPLICATION FAILED TO START
***************************

Description:

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)
└─────┘

Action:

Relying upon circular references is discouraged and they are prohibited by default. Update your application to remove the dependency cycle between beans. As a last resort, it may be possible to break the cycle automatically by setting spring.main.allow-circular-references to true.

解决办法：

增加如下配置可解决

spring:
  main:
    allow-circular-references: true
