Quarkus rest-client multipart file upload

Question

Following is the curl for a service

Service curl

curl --location --request POST 'https://someapi.com/api/v2/tickets' \
--header 'Authorization: Basic sdsdfsdfsdfsdf=' \
--header 'Cookie: _x_w=5_2' \
--form 'attachments[]=@"/home/Downloads/sample.pdf"' \
--form 'email="example@example.com"' 

The following setup works fine with Quarkus 2.12.2-Final, But it uploads the file with the static file name specified in @PartFileName(), my requirement is to upload the file with the dynamic name and content type, can someone please guide me on how can I update this to read the file name with extension dynamically?

Client

@Path("/v2/tickets")
@RegisterRestClient(configKey = "sampleKey")
public interface SampleClient {

    @POST
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    @Produces(MediaType.APPLICATION_JSON)
    SampleResponse create(
            @HeaderParam("Authorization") String authorization,
            @MultipartForm MultipartBody data);
}

MultipartBody

public class MultipartBody {

    @FormParam("attachments[]")
    @PartFilename("sample.pdf")
    @PartType(MediaType.APPLICATION_OCTET_STREAM)
    public File file;
    @FormParam("email")
    @PartType(MediaType.TEXT_PLAIN)
    public String email = "abcd@bixy.com";
}

Repository

public class SampleRepositoryImpl implements SampleRepository {

    @Inject
    @RestClient
    SampleClient client;

    @Override
    public SampleResponse create(MultipartBody request) {
        MultipartBody body = new MultipartBody();
        File f = new File("/home/Downloads/sample.pdf");
        body.setFile(f);
        return client.create(getAuthHeader(), body);
    }
}

Finally found the way, here it is

Updated client

@Path("/v2/tickets")
@RegisterRestClient(configKey = "sampleKey")
public interface SampleClient {

    @POST
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    @Produces(MediaType.APPLICATION_JSON)
    SampleResponse create(
            @HeaderParam("Authorization") String authorization,
            @MultipartForm MultipartFormDataOutput data);
}

Repository

public class SampleRepositoryImpl implements SampleRepository {
    @Inject
    @RestClient
    SampleClient client;

    @Override
    public void create(SampleData sampleData) {
        MultipartFormDataOutput dataOutput = new MultipartFormDataOutput();
        dataOutput.addFormData("email", sampleData.getData().getEmail(), MediaType.TEXT_PLAIN_TYPE);
        sampleData.getAttachments().forEach(x -> {
            dataOutput.addFormData(
                    "attachments[]",
                    x.getInputStream(),
                    MediaType.APPLICATION_OCTET_STREAM_TYPE,
                    x.getFileName());
        });
    }
}



public class Attachment {
    private InputStream inputStream;
    private String fileName;
    //getter setter
}

public class SampleData {
    private List<Attachment> attachments = new ArrayList<>();
    private OtherData data;
    public void addAttachment(Attachment attachment) {
        if (attachments == null) {
            attachments = new ArrayList<>();
        }
        attachments.add(attachment);
    }
    // getter setter
}
