Openfeign calling issue
Details: Openfeign client added to access method but facing issue while calling in another service method using a proxy, and other methods in a controller are working fine which are same service methods.
@EnableFeignClients @SpringBootApplication public class UserServiceV2Application {
public static void main(String[] args) {
SpringApplication.run(UserServiceV2Application.class, args);
}
}
@FeignClient(name="donation-service") public interface CharityDonationServiceProxy {
@GetMapping("/donation")
public List<Donation> getAllDonations();
// @GetMapping("/donation/all/{id}") // public List<Donation> getAllDonationsByName(@PathVariable(value="id") Long id);
