Service Registry Issue in Eureka Server

I'm facing issue with Spring Boot Registry with Eureka Server. The discovery service is registered and the other one is not registered.

My application.yml for discovery as below,


spring:
  application:
    name: swimming-pool-discovery-client
server:
  port: 8761
eureka:
  client:
    registerWithEureka: true
    fetchRegistry: true
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
  instance:
    preferIpAddress: true

The registration service application.yml as below.


spring:
  application:
    name: swimming-pool-reservation-service
server:
  port: 8181
eureka:
  client:
    registerWithEureka: true
    fetchRegistry: true
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
  instance:
    preferIpAddress: true

Discovery pom.xml as below,

Java Classes are,

@EnableEurekaServer
@SpringBootApplication
public class DisoveryApplication {

    public static void main(String[] args) {
        SpringApplication.run(DisoveryApplication.class, args);
    }
}

@SpringBootApplication
@EnableDiscoveryClient
@EnableEurekaClient
public class ReservationApplication {

    public static void main(String[] args) {
        SpringApplication.run(ReservationApplication.class, args);
    }
}

The below exception am facing,

Configuration of your discovery service is not correct. Change your application.yml to be like this 

spring:
  application:
    name: swimming-pool-discovery-client
server:
  port: 8761
eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false

Your configuration for registration service is correct. But you don't need @EnableDiscoveryClient and @EnableEurekaClient both. Just use @EnableEurekaClient
