I am trying to set up a simple spring cloud consul app.
I have a "distribution" service up and registered in consul (with the spring.application.name property set to "distribution")
I have an "acquisition" service that is trying to make a call to the "distribution" service using feign.
Here is my main class
@Configuration
@EnableAutoConfiguration
@EnableDiscoveryClient
@RestController
@EnableFeignClients
@EnableHystrix
public class Acquisition {
@Autowired
private DiscoveryClient discoveryClient;
@Autowired
private DistributionClient distributionClient;
@RequestMapping("/use-feign")
public String sendData() {
distributionClient.sendData(new Data("Hello World"));
return "sent";
}
@RequestMapping("/disco")
public String disco() {
List<ServiceInstance> list = discoveryClient.getInstances("distribution");
if (list != null && list.size() > 0) {
return list.get(0).getUri().toString();
}
return null;
}
public static void main(String[] args) {
SpringApplication.run(Acquisition.class, args);
}
}
here is my feign client
@FeignClient(value = "distribution")
interface DistributionClient {
@RequestMapping(method = RequestMethod.POST, value = "/data", consumes = "application/json")
void sendData(Data data);
}
and here is my pom.xml
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-consul-all</artifactId>

<groupId>org.springframework.cloud</groupId>

<artifactId>spring-cloud-consul-dependencies</artifactId>
<version>1.0.1.RELEASE</version>
<type>pom</type>

When I request the "/disco" Url, the url of the "distribution" service is properly retrieved, which means that the whole discovery thing is working as expected.
But, when I request the "/use-feign" url, I get the following exception :
com.netflix.client.ClientException: Load balancer does not have available server for client: distribution at com.netflix.loadbalancer.LoadBalancerContext.getServerFromLoadBalancer(LoadBalancerContext.java:468) ~[ribbon-loadbalancer-2.2.0.jar:2.2.0] at com.netflix.loadbalancer.reactive.LoadBalancerCommand$1.call(LoadBalancerCommand.java:184) ~[ribbon-loadbalancer-2.2.0.jar:2.2.0] at com.netflix.loadbalancer.reactive.LoadBalancerCommand$1.call(LoadBalancerCommand.java:180) ~[ribbon-loadbalancer-2.2.0.jar:2.2.0] at rx.Observable.unsafeSubscribe(Observable.java:8460) ~[rxjava-1.1.5.jar:1.1.5] at rx.internal.operators.OnSubscribeConcatMap.call(OnSubscribeConcatMap.java:94) ~[rxjava-1.1.5.jar:1.1.5] at rx.internal.operators.OnSubscribeConcatMap.call(OnSubscribeConcatMap.java:42) ~[rxjava-1.1.5.jar:1.1.5]
Am I missing any configuration ?
Thank you for your help.
