java - Is it possible to extend WebMvcConfigurationSupport and use WebMvcAutoConfiguration?

Question

I need to extend the WebMvcConfigurationSupport class too modify two things:

@Configuration
public class WebConfig extends WebMvcConfigurationSupport {
    @Override
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        RequestMappingHandlerMapping handlerMapping = super.requestMappingHandlerMapping();
        handlerMapping.setRemoveSemicolonContent(false);
        handlerMapping.setOrder(1);
        return handlerMapping;
    }
}

I like the defaults that are registered from the WebMvcAutoConfiguration class but due to the conditional annotation on the class, when I extend the WebMvcConfigurationSupport class it prevents the auto configuration from happening.

@Configuration
@ConditionalOnWebApplication
@ConditionalOnClass({ Servlet.class, DispatcherServlet.class,
    WebMvcConfigurerAdapter.class })
@ConditionalOnMissingBean(WebMvcConfigurationSupport.class)
@Order(Ordered.HIGHEST_PRECEDENCE + 10)
@AutoConfigureAfter(DispatcherServletAutoConfiguration.class)
public class WebMvcAutoConfiguration {...}

Is there to have the WebMvcAutoConfiguration class load without having to essentially copy/paste most of the code in that class?

Or is it possible to call RequestMappingHandlerMapping setOrder() and setRemoveSemicolonContent() from somewhere else so I can just use the @EnableWebMvc annotation and have the autoconfiguration class run without any issues?

Thanks in advance!

Extend from DelegatingWebMvcConfiguration instead of WebMvcConfigurationSupport, it will not prevent the autoconfig to take place:

@Configuration
public class WebConfig extends DelegatingWebMvcConfiguration {
    @Override
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        RequestMappingHandlerMapping handlerMapping = super.requestMappingHandlerMapping();
        handlerMapping.setRemoveSemicolonContent(false);
        handlerMapping.setOrder(1);
        return handlerMapping;
    }
}
