multipart won't work with amazon-lambda-rest?

[lianghua1987]

Are those two compatabile with each other? I always get null when trying upload files through rest api. Remove
amazon-lambda-rest dependency resolve the form upload issue, but how can I deploy to AWS lambda? Any suggestion would be appricated.

public class MultipartBody {
    @FormParam("file")
    @PartType(MediaType.WILDCARD)
    public InputStream file;

    @FormParam("fileName")
    @PartType(MediaType.TEXT_PLAIN)
    public String fileName;
}

@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
public void upload(@MultipartForm MultipartBody body) throws IOException {
     System.out.println(body.file.available()); // Null Pointer Exception here
}
