It Seems that annotation DubboReference.providedBy takes no effect on version 3.3.2, it searched "org.apache.dubbo.samples.microservices.sc.feign.UserServiceFeign" but not "dubbo-provider-for-dubbo" which was given by DubboReference.providedBy as codes below:

@DubboReference(providedBy = "dubbo-provider-for-dubbo", check = false) //RAJA
private UserServiceFeign userServiceFeign;

What you expected to happen

expected the annotation DubboReference.providedBy takes effect to search the given value

Anything else

Every time it occurs, wish this will be fixed , because it is a good way to migrate from springcloud to dubbo with little effort(no need to rewrite the business codes which will have very much cost). Maybe I will submit a pull request, I'm not sure.

Are you willing to submit a pull request to fix on your own?

Yes I am willing to submit a pull request on my own!

@aofall It takes no effect too, is it because of the below codes(the full path of UserServiceFeign is org.apache.dubbo.samples.microservices.sc.rest.UserServiceFeign)?

@DubboReference(providedBy = "spring-cloud-provider-for-dubbo", check = false)
private UserServiceFeign userService;

The error message below described that no provider available for service org.apache.dubbo.samples.microservices.sc.rest.UserServiceFeign：

@aofall Can DubboReference.providedBy takes effort when I want to switch the underlying protocol of feignclient from rest to triple?

laywin · 2024-12-25T03:34:05Z

@aofall Can DubboReference.providedBy takes effort when I want to switch the underlying protocol of feignclient from rest to triple?

no, DubboReference.providedBy is just a mapping between interface and instanceName, http is used in fact.

i think you can use @resource annotation when use UserServiceFeign, so the invoke mode just spring cloud invoke dubbo.
