如何使用retrofit发送包含多部分文件的requestparam？

public interface ApiService {
    @Multipart
    @POST("upload")
    Call<ResponseBody> uploadFiles(
        @Part("description") RequestBody description,
        @Part List<MultipartBody.Part> files
    );
}

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("https://api.example.com/")
    .build();

ApiService apiService = retrofit.create(ApiService.class);

RequestBody description = RequestBody.create(MediaType.parse("text/plain"), "File description");

List<MultipartBody.Part> files = new ArrayList<>();
for (String filePath : filePaths) {
    File file = new File(filePath);
    RequestBody fileRequestBody = RequestBody.create(MediaType.parse("image/*"), file);
    MultipartBody.Part filePart = MultipartBody.Part.createFormData("file", file.getName(), fileRequestBody);
    files.add(filePart);
}

Call<ResponseBody> call = apiService.uploadFiles(description, files);
call.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
        // 处理响应
    }

    @Override
    public void onFailure(Call<ResponseBody> call, Throwable t) {
        // 处理错误
    }
});
