エラー406とSpring MVCとBlueimp jQueryファイルアップロード

Question

私はBlueimp jQuery File Upload + Spring MVCを使用しています。私はアプリケーションをビルドするためにthis exampleに従っています。

画像をアップロードするために複数のファイルがアップロードされています。 画像は正常にアップロードされましたが、サーバーはエラー406を返しています。

私の問題はコントローラーメソッドの戻り値の型またはアプリケーションの設定ですが、修正できませんでした。

jQueryファイルアップロードはAJAXを使用してファイルをアップロードします。おそらくAJAXが問題の原因ですか？

@Controller 
public class UploadController { 

    private static final Logger logger = LoggerFactory 
      .getLogger(UploadController.class); 

    @Autowired 
    private ImagenManager imagenManager;

    @RequestMapping(value = "/uploadImagen.htm", method = RequestMethod.GET, headers="Accept=application/json") 
    public @ResponseBody Map listImagen() { 
     logger.debug("uploadGet called"); 
     List<Imagen> list = imagenManager.getImagenList(); 
     for (Imagen image : list) { 
      image.setUrl("/picture/" + image.getId()); 
      image.setThumbnailUrl("/thumbnail/" + image.getId());

Luke Woodwardがthis answerで説明しているように、/ uploadImagenで/uploadImagen.htmを置き換えると、エラー406は消えます。
