From source file:org.springframework.cloud.gateway.handler.predicate.PathRoutePredicateFactory.java

@Override
public Predicate<ServerWebExchange> apply(Config config) {
    final ArrayList<PathPattern> pathPatterns = new ArrayList<>();
    synchronized (this.pathPatternParser) {
        pathPatternParser.setMatchOptionalTrailingSeparator(config.isMatchOptionalTrailingSeparator());
        config.getPatterns().forEach(pattern -> {
            PathPattern pathPattern = this.pathPatternParser.parse(pattern);
            pathPatterns.add(pathPattern);
        });/*  w  w w.  ja v a2s. com*/
    }
    return exchange -> {
        PathContainer path = parsePath(exchange.getRequest().getURI().getRawPath());

        Optional<PathPattern> optionalPathPattern = pathPatterns.stream()
                .filter(pattern -> pattern.matches(path)).findFirst();

        if (optionalPathPattern.isPresent()) {
            PathPattern pathPattern = optionalPathPattern.get();
            traceMatch("Pattern", pathPattern.getPatternString(), path, true);
            PathMatchInfo pathMatchInfo = pathPattern.matchAndExtract(path);
            putUriTemplateVariables(exchange, pathMatchInfo.getUriVariables());
            return true;
        } else {
            traceMatch("Pattern", config.getPatterns(), path, false);
            return false;
