Some Route Predicates Don't Work With Regex Patterns

[ryanjbaxter]

The cookie, header, and query route predicate factories don't match .* patterns and instead return a 404. At the very least it should return a 500, but I believe these patterns should match

spring:  
  cloud:    
    gateway:      
      routes:      
      - id: query_route        
         uri: https://example.org        
         predicates:        
         - Query=test, a.*b

spring:  
  cloud:    
    gateway:      
      routes:      
      - id: header_route        
         uri: https://example.org        
         predicates:        
         - Header=Test, a.*b

spring:  
  cloud:    
    gateway:      
      routes:      
      - id: header_route        
         uri: https://example.org        
         predicates:        
         - Cookie=test, a.*b

Could you please specify exact steps to reproduce the problem? What is your Spring Boot/Spring Cloud version? I tried to reproduce the issue myself, but I didn't. Here's a small MRE that doesn't reproduce it

package com.example.gatewaydemo.routeDefinition;

import org.junit.jupiter.api.Test;
import reactor.core.publisher.Mono;
import reactor.test.StepVerifier;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.web.server.LocalServerPort;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.ResponseEntity;
import org.springframework.web.reactive.function.client.WebClient;

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
public class RouteDefinitionRouteLocatorTest {
	@LocalServerPort
	int port;

	@Test
	void test_ab() {
		testWithTestHeaderValue("ab");
	}

	@Test
	void test_aab() {
		testWithTestHeaderValue("aab");
	}

	private void testWithTestHeaderValue(String headerValue) {
		Mono<ResponseEntity<Void>> responseEntityMono = WebClient.builder()
				.baseUrl("http://localhost:" + port)
				.build()
				.get()
				.header("test", headerValue)
				.retrieve()
				.toBodilessEntity();
		StepVerifier.create(responseEntityMono)
				.expectNextMatches(r -> r.getStatusCode().is2xxSuccessful())
				.verifyComplete();
	}

	@Configuration
	@EnableAutoConfiguration
	static class RouteDefinitionRouteLocatorConfig {
	}
}
