Spring Cloud OpenFeign

Feign is a declarative web service client. It makes writing web service clients easier. To use Feign create an interface and annotate it.

With Feign, URLs are not hardcoded and Feign integrates with Ribbon and Eureka automatically. To use it you must add this dependency:

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

Then, you must add the @EnableFeignClients annotation to the main class and declare a Feign client using the @FeignClient annotation in the interface:

@FeignClient(name = "other-service-name")
public interface Proxy {

  @GetMapping("/other-service-uri/{variable}")
  public Response getResponse(
      @PathVariable String variable);

}

Now, you can use it:

Response response = proxy.getResponse(variable);
