405メソッドが許可されていませんが、RestEasyでHTTPステータス500となっています

Question

RestEasy Frameworkを使用したRestful Serviceの開発中です。 javax.ws.rs.NotAllowedException: RESTEASY003650: No resource method found for POST, return 405 with Allow header.

すでにExceptionMapperを使用してNotAllowedExceptionためにErrorHandlerを書かれ、javax.ws.rs.core.Applicationを拡張ルートアプリケーションでプロバイダを登録 - それは405が取り扱うことになるとのトラブルに直面して

。

しかし、それでも500エラーを返し、HTTPステータスを405ではなく500に設定します.400と404用に書かれた他のハンドラは正常に動作しますが、 RESTEasyのの最新バージョン使用

：3.0.16.Final

はここNotAllowedExceptionHandlerとアプリケーションで同じを登録するためのコードです。

シナリオ：誤ったHTTPメソッドを使用してリソースURLを実行しようとしました - PATCHの代わりにPOST。ここで

は同じのための例外スタックトレースです：

この点で助けてください。

RestEasyは処理方法を知らないAPIResponse。

Response.status(response.getStatus()).entity(response).type(MediaType.<type>).build(); 

JSONタイプ用などのためのコードは以下のようになります：

Response.status(response.getStatus()).entity(response).type(MediaType.APPLICATION_JSON).build(); 

詳しい方法：

@Provider 
    public class NotAllowedExceptionHandler implements ExceptionMapper <NotAllowedException> 
     { 
      @Override 
      public Response toResponse(NotAllowedException exception) 
       { 
        String bodyOfResponse = exception.getMessage(); 
        APIResponse response = new APIResponse(false , null , Status.METHOD_NOT_ALLOWED , HttpServletResponse.SC_METHOD_NOT_ALLOWED , 
          bodyOfResponse); 
        return Response.status(response.getStatus()).entity(response).type(MediaType.APPLICATION_JSON).build(); 
       } 
     }
