webflux equivalent of WebMvcConfigurer

Question

I'm migrating an app form spring mvc to spring webflux and I can't figure out what's the equivalent of this webMvc conf :

@Configuration
public class PathMatchingConfigurationAdapter implements WebMvcConfigurer {

    @Override
    public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
        configurer.favorPathExtension(false);
    }
}

any idea is welcome

Answer 1

Spring WebFlux does not support suffix pattern matching, see SPR-15639 for more information on the rationale behind that decision.

As a replacement, you can use a ParameterContentTypeResolver which does the same thing but with a query parameter like format=json. You can configure this with:

@Configuration
public class WebFluxConfig implements WebFluxConfigurer {

  public void configureContentTypeResolver(RequestedContentTypeResolverBuilder builder) {
    builder.parameterResolver().headerResolver();
  }
}
