How to use regexmapper based routing in Zuul? PatternServiceRouteMapper not working? - spring-cloud

Question

What I try to achieve is a routing for example:
http://zuul-host:8080/v1/foo/hello to my service foo-v1, resource hello
I'm trying out the regexmapper example described at http://cloud.spring.io/spring-cloud-netflix/spring-cloud-netflix.html
My problem is that I see that a service called foo-v1 gets mapped to /v1/foo in the PatternServiceRouteMapper but then I'm not able to call that route. It's also no visible at /mappings. Do I have to activate that route somewhere?
Setup
Foo Service
application.properties
server.port=9092
spring.application.name=foo-v1
eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/
eureka.instance.healthcheck.enable=true
Zuul
My configuration class Routings.java. I added some sysout log output for the service mapping and I get foo-v1 -> v1/foo in the log. Therefore this mapping should be active.
#Configuration
public class Routings {
#Bean
public PatternServiceRouteMapper serviceRouteMapper() {
return new PatternServiceRouteMapper(
"(?<name>^.+)-(?<version>v.+$)",
"${version}/${name}") {
#Override
public String apply(final String serviceId) {
String route = super.apply(serviceId);
System.out.println(serviceId + " -> " +route);
return route;
}
};
}
}
My ZuulApplication.java
#SpringBootApplication
#EnableZuulProxy
#ComponentScan
public class ZuulApplication {
public static void main(String[] args) {
SpringApplication.run(ZuulApplication.class, args);
}
#RefreshScope
#ConfigurationProperties("zuul")
public ZuulProperties zuulProperties() {
return new ZuulProperties();
}
}

Ok, found the solution.
Remove ignoredServices: '*' from the zuul config.
This happens if you work through the examples. They start with explicitly configured routes and ignore dynamic routings. It's in the documentation but made no sense to me at that point :-)
To skip having a service automatically added, set zuul.ignored-services to a list of service id patterns.
When using the regexmapper we start using services that get added automatically and that's the feature we disabled with ignoredServices: '*'
