Stéphane Leroy This service route mapper use Java 7 RegEx named group feature to rewrite a discovered service Id into a route. Ex : If we want to map service Id [rest-service-v1] to /v1/rest-service/** route service pattern : "(?.*)-(?v.*$)" route pattern : "${version}/${name}" This implementation uses Matcher.replaceFirst so only one match will be replaced.
