MessageBodyWriter找不到在JerseyTest中的media type = multipart/form-data

我正在嘗試在澤西島程序的資源類中爲POST方法創建一個測試。MessageBodyWriter找不到在JerseyTest中的media type = multipart/form-data

這裏的資源POST方法：

@POST @Path("/new") 
@Consumes(MediaType.MULTIPART_FORM_DATA) 
public Response HTTPPostMethod(@FormDataParam("file") InputStream fileIS, 
          @FormDataParam("file") FormDataContentDisposition contentDispositionHeader) { 
    // ... some code that handles the InputStream 
}

我ResourceConfig通過以下方式創建：

public class MyApp extends ResourceConfig { 

    public MyApp(String param) { 
     register(createMoxyJsonResolver());  
     register(MultiPartFeature.class); 
     register(MyResource.class); 
    } 

    private static ContextResolver<MoxyJsonConfig> createMoxyJsonResolver() { 
     final MoxyJsonConfig moxyJsonConfig = new MoxyJsonConfig(); 
     Map<String, String> nsPrefixManager = new HashMap<String, String>(1); 
     nsPrefixManager.put("http://www.w3.org/2001/XMLSchema-instance", "xsi"); 
     moxyJsonConfig.setNamespacePrefixMapper(nsPrefixManager).setNamespaceSeparator(':'); 
     return moxyJsonConfig.resolver(); 
    } 

    /** 
    * Start the Grizzly HTTP Server 
    * 
    */ 
    public final void startHttpServer(int port) { 
     try { 
      final String url = "http://localhost:" + port + "/myapp"; 
      final HttpServer server = 
        GrizzlyHttpServerFactory 
         .createHttpServer(URI.create(url), this); 

      Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() { 
       public void run() { 
        server.shutdown(); 
       } 
      })); 
      Thread.currentThread().join(); 

     } catch (InterruptedException e) { 
      e.printStackTrace(); 
     } 
    } 

    public static void main(String[] args) { 
     try { 
      final MyApp app = new MyApp(args[1]); 
      int port = Integer.parseInt(args[0]); 
      app.startHttpServer(port); 
     } catch(NumberFormatException e) { 
      e.printStackTrace(); 
     } 
    } 
}

我的球衣測試設置：

public class TestBase extends JerseyTest { 

    protected Application app; 
    protected static final String param = "myparam"; 

    @Override 
    protected Application configure() { 
     // The MultiPartFeature is registered. 
     this.app = new MyApp(param); 
     return app; 
    } 
}

最後，測試這是造成問題：

public class MyResourceTest extends TestBase { 

// ... 

    @Test 
    public void testHTTPPost() { 

     try { 

      FileDataBodyPart filePart = new FileDataBodyPart("file", new File("path/to/a/file/i/know/exists")); 
      FormDataMultiPart formDataMultipart = new FormDataMultiPart(); 
      FormDataMultiPart multipart = (FormDataMultiPart)formDataMultipart.bodyPart(filePart); 

      Response result = target("/myResource/new").request().post(Entity.entity(multipart, multipart.getMediaType())); 
      formDataMultipart.close(); 
      multipart.close(); 

      assertEquals(Response.Status.OK.getStatusCode(), result.getStatus()); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 

// ... 

}

我總是得到錯誤：

我試圖在TestBase下面的代碼，但沒有奏效：

@Override 
    protected Application configure() { 
     ResourceConfig app = new ResourceConfig(); 
     app.register(MultiPartFeature.class); 
     app.register(MyResource.class); 
     this.app = app; 
     return app; 
    }

同樣的錯誤。我在這裏做錯了什麼？

這類似於https：//開頭計算器。 com/questions/19668426/how-to-resolve-messagebodywriter-not-found-for-media-type-multipart-form-data-er –

MultiPartFeature註冊所需的MessageBodyWriter/MessageBodyReader以處理多部分。您已經在服務器上註冊了它（它將使用讀取器反序列化入站請求實體），但是您還需要在客戶端（使用編寫器序列化出站請求實體）上註冊它。

實際上有幾個地方你可以註冊它。一對夫婦與WebTarget或Client。如果你想與客戶端進行註冊，就可以在JerseyTest

@Override 
public void configureClient(ClientConfig config) { 
    config.register(MultiPartFeature.class); 
}

覆蓋configureClient(ClientConfig)或者與WebTarget，你可以簡單地做

target(...).register(MultiPartFeature.class)..

謝謝！接受一分鐘。 'configureClient'方法並使它工作。 – luispcosta
