Usage

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

private Mono<String> resolveResourceUrl(PathContainer lookupPath) {
    return this.handlerMap
            .entrySet().stream().filter(entry -> entry.getKey().matches(lookupPath)).sorted((entry1,
                    entry2) -> PathPattern.SPECIFICITY_COMPARATOR.compare(entry1.getKey(), entry2.getKey()))
            .findFirst().map(entry -> {
                PathContainer path = entry.getKey().extractPathWithinPattern(lookupPath);
                int endIndex = lookupPath.elements().size() - path.elements().size();
                PathContainer mapping = lookupPath.subPath(0, endIndex);
                if (logger.isTraceEnabled()) {
