As mentioned by @g00glen00b in comments Eureka is not used for communication between microservices. Its for service discovery. There are two ways that I know ofthrough which you can communicate with other Microservices :

1. RestTemplate
2. Feign Client

RestTemplate is very simple to use. It does not require configurations.

e.g.

   ResponseType obj=  new RestTemplate().getForObject(URL, ResponseType.class, params);

url - the URL

responseType - the type of the return value

params- the variables to expand the template
