Send multiple key in Feign Client

I have a nxt request POST with form url encoded using Feign Client

@FeignClient(
        url = "${url}", configuration = NxtApi.Configuration.class)
public interface NxtApi {

    @PostMapping(value = "nxt", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
    String new(
            @RequestParam String requestType, @RequestBody Map<String, ?> payload);

    class Configuration {

        @Bean
        Encoder feignFormEncoder(ObjectFactory<HttpMessageConverters> converters) {
            return new SpringFormEncoder(new SpringEncoder(converters));
        }

        @Bean
        Logger.Level feignLoggerLevel() {
            return Logger.Level.FULL;
        }

    }
}

I want to send the same key with two values

  Map<String, Object> param = new HashMap<>();
  param.put("filter", valueOne);
  param.put("filter", valueTwo);
  api.new("asset",param);

I need something like that

filter=valueOne&filter=valueTwo

But it's being sent like this (Request response in the log)

filter=[valueOne,valueTwo]

Thanks for any help.

You will have to use a List of String values instead of a Map.

@PostMapping(value = "nxt", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
String new(@RequestParam String requestType, @RequestParam("filter") List<String> filter, @RequestBody Map<String, ?> payload);

as I found it here: Spring Cloud Feign Client @RequestParam with List parameter creates a wrong request
