Spring Cloud - Registry Service port customization

Question

I'd like to customize the Eureka port with Spring Cloud. With the default port below, the services registry sees itself right (within the provided GUI)

spring:
  application:
    name: services-registry
server:
  port: 8761

eureka:
  instance:
    hostname: localhost
    nonSecurePort: ${server.port}
  client:
    register-with-eureka: true
    fetch-registry: false
    service-url:
      default-zone: http://${eureka.instance.hostname}:${server.port}/eureka/

But if I just change server.port to 8787, no service can register itself, not even the services registry itself.

Can someone explain this issue and save my day? Thanks!

Ok, got it... the label after service-url property (which can be aliased as serviceUrl in YML) is a HashMap KEY, not a property label. So it has to be kept as a Camel Case tag in any ways!

eureka.client.service-url.defaultZone=http://[myIP@]:8787/eureka
