I have created a custom `RequestMappingHandlerMapping` with the latest version of Spring as follows so I can define a custom version annotation.

WebConfiguration,

```
@Configuration
@ConditionalOnClass({ ApiVersionedResource.class })
public class WebConfiguration  {

    @Bean
    @Primary
    public ContentNegotiationManager contentNegotiationManager() {
        ContentNegotiationManagerFactoryBean contentNegotiationManagerFactoryBean = new ContentNegotiationManagerFactoryBean();
        Map<String, MediaType> mediaTypes = new HashMap<>();
        mediaTypes.put("json", MediaType.APPLICATION_JSON);
        contentNegotiationManagerFactoryBean.addMediaTypes(mediaTypes);
        contentNegotiationManagerFactoryBean.afterPropertiesSet();
        return contentNegotiationManagerFactoryBean.getObject();
    }

    @Bean
    public WebMvcRegistrationsAdapter webMvcRegistrationsHandlerMapping() {
        return new WebMvcRegistrationsAdapter() {
            @Override
            public RequestMappingHandlerMapping getRequestMappingHandlerMapping() {
                CustomRequestMappingHandlerMapping handlerMapping = new CustomRequestMappingHandlerMapping();
                handlerMapping.setOrder(0);
                handlerMapping.setRemoveSemicolonContent(false);
                handlerMapping.setContentNegotiationManager(contentNegotiationManager());
                return handlerMapping;
            }
        };
    }
}

```

CustomRequestMappingHandlerMapping,

```
public class CustomRequestMappingHandlerMapping extends RequestMappingHandlerMapping {
    @Override
    protected RequestCondition<?> getCustomTypeCondition(Class<?> handlerType) {
        ApiVersionedResource typeAnnotation = AnnotationUtils.findAnnotation(handlerType, ApiVersionedResource.class);
        return createCondition(typeAnnotation);
    }

    @Override
    protected RequestCondition<?> getCustomMethodCondition(Method method) {
        ApiVersionedResource methodAnnotation = AnnotationUtils.findAnnotation(method, ApiVersionedResource.class);
        return createCondition(methodAnnotation);
    }

    @Override
    protected boolean isHandler(Class<?> beanType) {
        return super.isHandler(beanType) && (AnnotationUtils.findAnnotation(beanType, ApiVersionedResource.class) != null);
    }

    private RequestCondition<?> createCondition(ApiVersionedResource versionMapping) {
        if (versionMapping != null) {
            return new ApiVersionedResourceRequestCondition(versionMapping.media(), versionMapping.version());
        }

        return null;
    }
}

```

However, this is causing the following error during compilation and I have no idea what is causing it.

```

Description:

The bean 'requestMappingHandlerMapping' could not be injected as a 'org.springframework.web.servlet.mvc.method.RequestMappingInfoHandlerMapping' because it is a JDK dynamic proxy that implements:

Action:

Consider injecting the bean as one of its interfaces or forcing the use of CGLib-based proxies by setting proxyTargetClass=true on @EnableAsync and/or @EnableCaching.
