@EnableDiscoveryClient doesn't register properly

[Kaffeekaethe]

I hope this is the right place with my issue.

I've set up a Spring Boot Application two Classes.

The ServiceClass has the Annotations

@SpringBootApplication
@EnableDiscoveryClient

And I have a seperate ControllerClass with the Annotations

@EnableAutoConfiguration
@Controller

I run it with SpringApplication.run(ControllerClass.class, args);

If I use the @EnableDiscoveryClient at the ControllerClass I get the Error:

but if I use it for the ServiceClass it compiles and starts.

However, I connect to my Consul-Server, but I do not register. The only thing that is send is:

'2016/04/17 12:33:46 [DEBUG] http: Request GET /v1/kv/config/service/?recurse&token=<hidden> (0) from=127.0.0.1:52166

but from what I understand, my service would actually need to send a Post Request with the information in JSON-Format.

I do not really understand where I am going wrong or if there's something wrong with the annotation.

I ran into the same issue. In my case, it happened because of a collision with a transitive dependency. I had to setup an exclusion rule for the transitive dependency:

compile("org.springframework.cloud:spring-cloud-starter-consul-all") {
    exclude(group: 'org.springframework.cloud', module: 'spring-cloud-netflix-core')
}

[spencergibb]

@n3integration that's actually bad, because you won't get ribbon support. Are you using the spring boot dependency management plugin?

[spencergibb]

@Kaffeekaethe can you show your configuration?

[n3integration]

@spencergibb - Thanks for the tip and being so responsive. In one of my use cases, I may need ribbon support. Also, I am using the spring boot dependency management plugin. I was receiving a similar stack trace as @Kaffeekaethe, because of the Eureka and Consul discovery clients, so I excluded the netflix-core dependency to work around the conflict. Is there another way around this without excluding the dependency?

[spencergibb]

You'll have to share a project that duplicates the problem.

[n3integration]

I apologize for the delay in getting back. In my case, I am also importing spring-cloud-starter-zuul, which also imports the ribbon dependency. So I should be all set, correct?

[spencergibb]

You should be, but if you're still having the problem, I'll need to see a sample project.
