Usage

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 -> {//from w ww  .j  av  a  2s  .com
        mapping.getHandlerMap().forEach((pattern, handler) -> {
            if (handler instanceof ResourceWebHandler) {
                ResourceWebHandler resourceHandler = (ResourceWebHandler) handler;
                if (logger.isDebugEnabled()) {
                    logger.debug("Found resource handler mapping: URL pattern=\"" + pattern + "\", "
                            + "locations=" + resourceHandler.getLocations() + ", " + "resolvers="

                this.handlerMap.put(pattern, resourceHandler);
