Configured adapter for `@HttpExchange` proxy group is ignored (Boot 4)

[ch4mpy]

I'm trying to integrate my existing RestClient and WebClient auto-configuration with what is added to Boot 4. However, whatever I configure with the following is ignored:

@Configuration
@ImportHttpServices(group = "bidule", types = {BiduleApi.class})
@ImportHttpServices(group = "machin", types = {MachinApi.class})
public class RestConfiguration {

  @Bean
  RestClientHttpServiceGroupConfigurer groupConfigurer(RestClient biduleClient,
      RestClient machinClient) {
    return groups -> {
      groups.forEachGroup((group, clientBuilder, factoryBuilder) -> {
        if ("bidule".equals(group.name())) {
          factoryBuilder.exchangeAdapter(RestClientAdapter.create(biduleClient));
        } else if ("machin".equals(group.name())) {
          factoryBuilder.exchangeAdapter(RestClientAdapter.create(machinClient));
        }
      });
    };
  }
}

Shouldn't the ProxyHttpServiceGroup::createProxies method set the proxyFactoryBuilder's exchangeAdapter only if it isn't set already?

I think that's an issue you'll need to raise on the spring-framework issue tracker. ProxyHttpServiceGroup is part of that repository.

I'm afraid I can't transfer the issue.
