discovery.locator.enabled caused routes.filters invalid

Spring:
  Cloud:
    Gateway:
       # Setting discovery.locator.enabled=true will invalidate filters
      Discovery:
        Locator:
          Enabled: true
      Routes:
      - id: service_appraisal
        Uri: lb://appraisal
        Predicates:
        - Path=/appraisal/**
        Filters:
        - name: Hystrix
          Args:
            Name: fallbackcmd
            fallbackUri: forward:/fallback
        - name: Retry
          Args:
            Retries: 3
            Statuses: BAD_GATEWAY

The above configuration will cause the filters part to be invalid. Request http://localhost:5678/APPRAISAL/test, the routing result is as follows (Debug result):

There is no hystrix and retry related filter in the route.

In order to use filter, the current solution is as follows:

Spring:
  Cloud:
    Gateway:
       # Do not enable discovery.locator.enabled
# discovery:
# locator:
# enabled: true
      Routes:
      - id: service_appraisal
        Uri: lb://appraisal
        Predicates:
        - Path=/appraisal/**
        Filters:
        # Solve the path problem
        - RewritePath=/appraisal/(?.*), /$\{segment}
        - name: Hystrix
          Args:
            Name: fallbackcmd
            fallbackUri: forward:/fallback
        - name: Retry
          Args:
            Retries: 3
            Statuses: BAD_GATEWAY

** As configured above, request http://localhost:5678/APPRAISAL/test, the routing result is as follows (Debug result)**:

The route contains hystrix and retry related filters

Start with the RouteDefinitionRouteLocator and RoutePredicateHandlerMapping behavior shown in the logs, comparing a configured route with the discovery-generated route when discovery.locator.enabled is true. Reproduce the configuration using the Spring Boot 2.0.3 and Spring Cloud Finchley.SR1 versions given; done when discovery-generated routes retain the configured Hystrix and Retry filters.
