dubbo with sentinel && @dubbotransported

[halower]

Which Component Dubbo

Describe the bug

1. the 0.9.0 version uses @dubbotransported () to find that it does not appear to have been invoked through Dubbo because the service provider's RpcContext.getContext (). getUrl () is always null

2. if used Sentinel and @FeignClient at the same time, fallback will be ineffective, remove Dubbo will return to normal, but hystrix no problem

To Reproduce Steps to reproduce the behavior: to Scenario 1:

@FeignClient(value = "demo-service",fallback = UserServiceMock.class)
@DubboTransported()
public interface TestService{
    @PostMapping("/api/user/hello")
    String login(@RequestBody LoginUserDto userDto);
}

@Service
@RestController
public class DubboTestService implements TestService {

    @Override
    public String login(LoginUserDto userDto) {
        return RpcContext.getContext().getUrl() + "[echo]:" + userDto.toString();
    }
}

to Scenario 2:

implementation ("org.springframework.cloud:spring-cloud-alibaba-dubbo:sentinel:0.9.0.RELEASE")
implementation ("org.springframework.cloud:spring-cloud-starter-alibaba-sentinel:0.9.0.RELEASE")

feign:
  sentinel:
    enabled: true

Maybe it is not compatibility with Sentinel.

I will check it soon.
