gateway with eureka discovery only match upper case url

Just test Finchley.RC1, and eureka server version is 1.4.4.RELEASE. use lower case service id will got 404, only upper case can find service.

find in DiscoveryClientRouteDefinitionLocator:

String serviceId = instance.getServiceId();

there get the upper case serviceId, and predicate will be ‘Path=/SERVICE_ID/**’.

Setting spring.cloud.gateway.discovery.locator.lowerCaseServiceId=true in gateway service will make your service id lowercase by default

After 3d2364a you can now do this:

spring.cloud.gateway.discovery.locator:
  filters: 
    - name: RewritePath
      args: 
        regexp: "'/' + serviceId.toLowerCase() + '/(?<remaining>.*)'"
        replacement: "'/$\\{remaining}'"
      
  predicates: 
    - name: Path
      args: 
        pattern: "'/'+serviceId.toLowerCase()+'/**'"

Though that is a lot of boiler plate for an option that will be used fairly often, so more to come.
