Feign Client cannot communicate with a method inside of eureka server - spring-boot

Question

I have a eureka server configured and inside that eureka server I have written a rest api. Now I have a eureka client service and I am trying to call one of the method of eureka service using feign from client service. But I am getting an error "Load balancer does not have available server for client: eureka-service".
But If I call api from a client service to another client service using feign then it is giving successful result. Just can't call API from eureka service.
eureka-service is application name of my eureka server.
#EnableEurekaServer
#SpringBootApplication
public class EurekaApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaApplication.class, args);
}
}
#RestController
#RequestMapping("test")
public class TestController {
#GetMapping
public String test(){
return "test success";
}
}
bootstrap.yml of eureka service
eureka:
client:
registerWithEureka: false
fetchRegistry: false
eureka-server-read-timeout-seconds: 60
eureka-server-connect-timeout-seconds: 60
serviceUrl:
defaultZone: http://localhost:8763/eureka/
dashboard:
enabled: true
spring:
application:
name: eureka-service
And client service is:
#SpringBootApplication
#EnableFeignClients
#EnableDiscoveryClient
public class ClientApplication {
public static void main(String[] args) {
SpringApplication.run(ClientApplication.class, args);
}
}
#FeignClient("eureka-service")
public interface TestFeign {
#GetMapping("test")
String test();
}
bootstrap.yml of client service
eureka:
client:
registerWithEureka: true
fetchRegistry: true
eureka-server-read-timeout-seconds: 60
eureka-server-connect-timeout-seconds: 60
serviceUrl:
defaultZone: http://localhost:8763/eureka/
spring:
application:
name: client-service
feign:
hystrix:
enabled: true
ERROR log : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is com.netflix.hystrix.exception.HystrixRuntimeException: TestFeign#test() failed and no fallback available.] with root cause
com.netflix.client.ClientException: Load balancer does not have available server for client: eureka-service.
How can we solve this issue. Thanks for help in advance.

You need to scan your interfaces that declare they are FeignClients with the #EnableFeignClients annotation in your main class and add the feign.hystrix.enabled=true property.
