Can i use Java Feign client to request for another API?

I have microservice why do some calculations. And there is public api where i can get some data. Can i use Feign to do request to this API?

Solution

  • Yes, you can do that :

    Step 1: create feign client

    @FeignClient(name="DemoClient", url="url of the api")
public interface DemoClient {
    @GetMapping(value="/get-demo",consumes=MediaType.APPLICATION_JSON_VALUE)
    List<Model> getData();
}

    Step 2 : Create Model

    class Model {

}

    Step 3 : Create Service Layer

    class DemoService {

   @Autowired
   DemoClient demoClient;

   public void getData() {
       List<Model> objData = this.democlient.getData();
   }

}

    Hope this will help
