Using enum as #PathVariable in FeignClient - spring

Question

I don't know how to make FeignClient working with enum serialization as #PathVariable.
I have enum type representing Access Type:
public enum StorageFileAccessType {
TOKEN(0),
SMSCODE(1);
private final int id;
private StorageFileAccessType(int id) {
this.id = id;
}
#JsonValue
public int getId() {
return id;
}
...
}
Each enum value has corresponding int value, which should be used during serialization.
Then I have FeignClient with one method for uploading file: it uploads file for given user and sets access type (token or smscode).
#FeignClient(value = "uploadClient", url = "${serverUrl}", configuration = { ClientConfig.class })
public interface UploadClient {
#RequestMapping(method = RequestMethod.POST, value = "files/write/{user}/{accessType}", consumes = MediaType.MULTIPART_FORM_DATA_VALUE,
produces = MediaType.APPLICATION_JSON_VALUE)
public Result uploadFile(#PathVariable("user") String user,
#PathVariable("accessType") StorageFileAccessType accessType,
#RequestPart("file") MultipartFile file);
}
Now when I call method, e.g:
feignClient.uploadFile("user", StorageFileAccessType.TOKEN, file);
I expect request is sent with URI: ${serverUrl}/files/write/user/0
but instead it is sent with URI: ${serverUrl}/files/write/user/TOKEN what means Enum serialization to integer is not performed and enum name is used.
When I use enum inside #RequestPart, serialization to int works correctly.
Is there any way to make this Enum serialization working also for #PathVariable?
Of course I can change method parameter to:
#PathVariable("accessType") int accessType
and pass int directly - and it works, but If possible I prefer using enum - as more cleaner solution.
