Spring boot & Swagger 2 UI & custom requestmappinghandlermapping - mapping issue

I have own RequestMappingHandlerMapping and I am using springfox-swagger-ui. After adding my custom mapping, I am not able to achieve swagger ui at http://localhost:8080/swagger-ui.html. Any ideas?

This is my configuration.

    @Configuration
       public class WebMvcConfig extends WebMvcConfigurationSupport {
    @Override
    @Bean
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        return new ApiVersionRequestMappingHandlerMapping("v");
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry
          .addResourceHandler("/webjars/**")
          .addResourceLocations("(META-INF/resources/webjars");
    }
}

Here's my pom.xml:

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.hateoas</groupId>
        <artifactId>spring-hateoas</artifactId>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>2.4.0</version>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>2.4.0</version>
    </dependency>
    <dependency>
        <groupId>javax.inject</groupId>
        <artifactId>javax.inject</artifactId>
        <version>1</version>
    </dependency>

I finally find it! The right configuration is this:

@Configuration
public class VersioningMappingHandlerConfig {

    @Bean
    public ApiVersionRequestMappingHandlerMapping customMappingHandlerMapping() {
        ApiVersionRequestMappingHandlerMapping handler = new ApiVersionRequestMappingHandlerMapping("v", 1, 1);
        handler.setOrder(-1);
        return handler;
    }

}

Note: there is no extends WebMvcConfigurationSupport and bean name is customMappingHandlerMapping
