Amazon web services – Can we use feign client with AWS API Gateway?

We have a couple of microservices managed using AWS API Gateway which also acts as a load balancer. We have not integrated spring cloud and eureka services to perform load balancing and invoke external service calls.

Does it make sense to replace RestTemplate with feign-client only for not writing unit test cases?

    Not sure how this is related to unit tests, but you can replace RestTemplate with Spring Cloud OpenFeign for a leaner, more readable API. It may also handle client-side load-balancing for you under the hood. However, you might wish to wait till Spring 6 release and switch to using the new Spring interface client instead.

    • We can use feign client without using the eureka server and config client. Feign client sits on top of the rest template.

    • So for better intercommunication between two microservices feign client works fine.

    • All you need to do is to supply additional parameter for url to the feign client @FeignClient along with name param

    • The port needs to be a fixed port and cannot be randomized provided by spring boot. So user server port

    @FeignClient(name = "user-profile-service",
    url="${client.user-profile-service.baseurl}")

    application.yml

    client:
  skill-service:
    baseurl: http://localhost:3202
