From source file:org.springframework.web.reactive.resource.ResourceUrlProvider.java

private void detectResourceHandlers(ApplicationContext context) {
    logger.debug("Looking for resource handler mappings");

    Map<String, SimpleUrlHandlerMapping> beans = context.getBeansOfType(SimpleUrlHandlerMapping.class);
    List<SimpleUrlHandlerMapping> mappings = new ArrayList<>(beans.values());
    AnnotationAwareOrderComparator.sort(mappings);

    mappings.forEach(mapping -> {/* w w  w . jav a2 s .  c om*/
        mapping.getHandlerMap().forEach((pattern, handler) -> {
