LoadBalancerRestClientHttpServiceGroupConfigurer does not set baseUrl for @ImportHttpServices groups

[goalfy1030]

Description:

Environment

• Spring Boot: 4.0.0
• Spring Cloud: 2025.1.0
• Spring Cloud Alibaba: 2025.1.0.0-SNAPSHOT

Problem

When using @ImportHttpServices with a service discovery name, the LoadBalancerRestClientHttpServiceGroupConfigurer does not set the baseUrl correctly, resulting in "Target host is not specified" error.

Configuration

@ImportHttpServices(group = "traffic-service", types = TrafficFeignService.class)
@SpringBootApplication
public class LinkApplication { }

@HttpExchange
public interface TrafficFeignService {
    @PostExchange("/api/traffic/v1/reduce")
    JsonData useTraffic(@RequestBody UseTrafficRequest request);
}

Expected

The LoadBalancerRestClientHttpServiceGroupConfigurer should automatically set
baseUrl = "http://traffic-service" based on the group name.

Actual

Caused by: org.apache.hc.core5.http.ProtocolException: Target host is not specified

Workaround

Manually create the HTTP Service proxy with @LoadBalanced RestClient.Builder.
