We can also inherit interfaces to avoid boilerplate code for the same type of services. Feign allows grouping common operations into convenient base interfaces. Let's see the following example:
@FeignClient(name="account-service")
public interface AccountService {
@GetMapping(value = "/account/customer/{customer}")
List<Account> findByCutomer (@PathVariable("customer") Integer customer);
...
}
We can inherit this interface in the creation of another FeignClient service:
@FeignClient("users")
public interface AdminAccountService extends AccountService {
...
}
