Custom RequestMappingHandlerMapping with MockMvc

I have a custom RequestMappingHandlerMapping class that interprets a special annotation as part of its mapping criteria. It is being instantiated as a bean thusly:

@Configuration
@EnableWebMvc
public class ConfigServletConfig extends WebMvcConfigurerAdapter {
    @Bean
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        RequestMappingHandlerMapping handlerMapping = new VersionRangeRequestMappingHandlerMapping();
        handlerMapping.setOrder(0);
        return handlerMapping;
    }
}

But when I create a MockMvc object for testing (with standaloneSetup) this mapping handler isn't being used. Without the extra annotation being taken into account, the mapping fails because I have multiple controller methods with the same @RequestMapping. The annotation is what differentiates them.

How can I configure MockMvc to use this custom mapping handler?

For those who's still in search, since Spring updated to version 5.0 (I believe) the custom MockMvc requestHandlerMapping configuration was introduced.

Example of usage:

MockMvcBuilders.standaloneSetup(new MyAwesomeController())
        .setCustomHandlerMapping(() -> new MyAwesomeRequestMappingHandlerMapping())
        .build();

You can configure with override getRequestMappingHandlerMapping method of WebMvcConfigurerAdapter. 

@Configuration
public class ConfigServletConfig extends WebMvcConfigurerAdapter {

    @Override
    public RequestMappingHandlerMapping getRequestMappingHandlerMapping() {
        RequestMappingHandlerMapping handlerMapping = new VersionRangeRequestMappingHandlerMapping();
        handlerMapping.setOrder(0);
        return handlerMapping;
    }
}

As of Spring Framework 4.3.x, it is currently not possible to register a custom RequestMappingHandlerMapping with the standaloneSetup() builder for MockMvc.

However, the team is considering adding such support in Spring Framework 5.0.

See SPR-15472 for further details.
