At present, when using spring-cloud-starter-dubbo, "dubbo.registry.address" is not configured as "spring-cloud://localhost" and registry are specified separately, there will be two instances of "org.apache.dubbo.config.RegistryConfig" in the spring container, which will cause this problem.
But using "spring-cloud://localhost" will become application level registration. If you do not want to use application level registration and continue to use interface level registration, it is recommended to use "dubbo-spring-boot-starter" instead of "spring-cloud-starter-dubbo".

I have found the cause of the problem in your demo, which will be fixed in the next version.
The current interim solution is not to pass `dubbo.provider.group` to specify a global group, use the group attribute in the @ DubboService annotation
