How can I change the feign URL during the runtime?

Question

@FeignClient(name = "test", url="http://xxxx")

How can I change the feign URL (url="http://xxxx") during the runtime? because the URL can only be determined at run time.

Answer 1

You can add an unannotated URI parameter (that can potentially be determined at runtime) and that will be the base path that will be used for the request. E.g.:

    @FeignClient(name = "dummy-name", url = "https://this-is-a-placeholder.com")     public interface MyClient {         @PostMapping(path = "/create")         UserDto createUser(URI baseUrl, @RequestBody UserDto userDto);     } 

And then the usage will be:

    @Autowired      private MyClient myClient;     ...     URI determinedBasePathUri = URI.create("https://my-determined-host.com");     myClient.createUser(determinedBasePathUri, userDto); 

This will send a POST request to https://my-determined-host.com/create (source).
