        List<RouteDefinition> definitions = locator.getRouteDefinitions().collectList().block();
        if (definitions == null) {
            return Collections.emptySet();
        }
        definitions.stream().filter(routeDefinition -> routeDefinition.getId().matches(".*-service-impl")).forEach(routeDefinition -> {
            String name = (String) routeDefinition.getMetadata().get("name");
            List<PredicateDefinition> predicates = routeDefinition.getPredicates();
            PredicateDefinition predicateDefinition = predicates.getFirst();
            String pattern = predicateDefinition.getArgs().get("pattern");
            String prefix = pattern.replace("/**", "").replace("/", "");
            SwaggerUrl swaggerUrl = new SwaggerUrl(name, prefix + DEFAULT_API_DOCS_URL, null);
            urls.add(swaggerUrl);

v-file-service-impl:
application.yml

dubbo:
  application:
    name: ${spring.application.name}
    logger: slf4j
  protocol:
    name: tri
    port: 50053
  registry:
    address: nacos://@nacos.discovery.server-addr@

If I access the file service's api document address (http://localhost:8000/file/v3/api-docs) through the gateway, I will find that success and failure alternate. If I directly use the file service's ip:port to access the document address (http://localhost:11002/v3/api-docs), there will be no error.

success:

fail:

file-service is a dubbo provider. If you remove all the provider's @ DubboServices, no error will be reported.

What you expected to happen

There is no exception when requesting /v3/api-docs

Anything else

I guess the problem is caused by the adaptation of triple protocol to spring, but I am not very familiar with triple protocol. I would like to ask the developer to help me troubleshoot it.

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