spring cloud unable to route to internal application

Question

I am using spring cloud to route application but unable to do so below are the details

Gateway configuration

   port: 8080
debug: true
spring:
   application:
      name: cloud-gateway
   cloud:
      gateway:
         discovery:
            locator:
               enabled: true
               lower-case-senstive: true
      routes:
      -  id: product-composite
         uri: localhost:7000
         predicates:
         -  Path: /product-composite/**

eureka:

   instance:
      hostname: localhost
   client:
      registerWithEureka: false
      fetchRegistry: false
      serviceUrl:
         defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
server:
   port: 8761
   waitTimeInMsWhenSyncEmpty: 0
   response-cache-update-interval: 5000
management.endpoints.web.exposure.include: '*'

Product Composite Service* (I am trying to call)

   port: 7000
spring:
   application:
      name: product-composite
eureka:
   client:
      serviceUrl:
         defaultZone: http://localhost:8761/eureka/
         initialInstanceInfoReplicationIntervalSeconds: 5
         registryFetchIntervalSeconds: 5
      register-with-eureka: true
      fetch-registery: true
   instance:
      leaseRenewalIntervalInSeconds: 5
      leaseExpirationDurationInSeconds: 5

Path

@RestController
public class ProductCompositeServiceController {

    @GetMapping
    public String getString() {
        return "Hello grom product CompositeController";
    }
}

Can you help? If needed I can provide more details Note: if product-composite-servcie is called without eureka I am getting response but with eureka I am getting

404 Resource not found

Edit Below is the stacktrace I am getting so far:

2020-06-24 22:22:05.252 DEBUG 38876 --- [or-http-epoll-2] o.s.w.r.handler.SimpleUrlHandlerMapping  : [63939523-1] Mapped to ResourceWebHandler ["classpath:/META-INF/resources/", "classpath:/resources/", "classpath:/static/", "classpath:/public/"]

I also tried to add path as

routes:
      -  id: product-composite
         uri: localhost:7000
         predicates:
         -  Path: /product-composite/**
         filters:
         - RewritePath: /product-composite/(?<segment>.*), /$\{segment}

It looks like your service responds to "/" but your route is "/product-composite" which would 404. You need to modify the path using StripPath, SetPath or RewritePath. — spencergibb
@spencergibb, Thank you for your comment. but seems like I am missing some small detail here. Tried to Add your mentioned suggestions but it seems like not working — emotionlessbananas
adding spring.webflux.base-path=product-composite to product-composite-service solved my problem — emotionlessbananas

You don't have a path in your controller. Try

@GetMapping("/product-composite")
