Feign - Hystrix - feign.RetryableException: Connection refused: no further information executing GET

Question

I have

@FeignClient(name="verbservice", fallback = VerbClientFallback.class)
public interface VerbClient {
    @GetMapping
    public String getVerbWord();
}

and

@Component
public class VerbClientFallback implements VerbClient {
    @Override
    public String getVerbWord() {
        return "fallback";
    }
}

App

@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
@EnableHystrix
public class SentenceAppApplication {
...}

Controller

@Autowired
private VerbClient verbClient;
....
return verbClient.getVerbWord() + ....other;

application.properties

feign.hystrix.enabled=true

Versions

Spring boot 2.5.4

<properties>
    <java.version>11</java.version>
    <spring-cloud.version>2020.0.3</spring-cloud.version>
</properties>

Goal: stop the verb service and see if fallback is invoked or not.

Problem:

nested exception is feign.RetryableException: Connection refused: no further information executing GET http://verbservice] with root cause

I tried steps in this link...but it is not working Feign Hystrix fallback not working

Answer 1

It seems the property

feign.hystrix.enabled=true

is changed to

feign.circuitbreaker.enabled=true
