Spring Cloud Netflix How do I handle exceptions in case of connection error for the eureka client ?

I 'm using the eureka-client in the spring boot2. However, the eureka server is off and a connection error is output. I want to catch the error and do something else. How do I handle exceptions in case of connection error for the eureka client ?

-------------- exception ------------------

No need to cross post https://github.com/Netflix/eureka/issues/1111

How are you using the eureka client?

Comment From: JangCool

i'm using the openfeign and the eureka-client.

Maybe. I think will work behind at the eureka-client when using the openfeign.

I want to handle exceptions for connection errors.

----application -----

@SpringBootApplication @EnableFeignClients public class Application {

---- openfeign call -------

@FeignClient(name = "gateway") public interface SampleClient {

@RequestMapping(method=RequestMethod.GET, value="/article/sports/{category}")
public String getData(@PathVariable("category") String category);

}

---- pom.xml ----

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-openfeign</artifactId>
    </dependency>

Eureka client works asynchronously. There is no way to handle those errors.

@spencergibb Is there any active way to catch such errors？Do I only wait other server happen error?
