jax-rs客戶端下載文件

在我的項目中，我打電話給一個休息服務，它返回MediaType.APPLICATION_OCTET_STREAM。我已經爲此寫了一個球衣客戶端。但我沒有得到500錯誤。在日誌中我看到的錯誤：jax-rs客戶端下載文件

SEVERE: MessageBodyWriter not found for media type=application/octet-stream, type=class java.io.ByteArrayOutputStream, genericType=class java.io.ByteArrayOutputStream.

編寫的代碼如下，

ClientConfig clientConfig = null; 
     Client client = null; 
     WebTarget webTarget = null; 
     Invocation.Builder invocationBuilder = null; 
     Response response = null; 
     InputStream inputStream = null; 
     OutputStream outputStream = null; 
     int responseCode; 
     String responseMessageFromServer = null; 
     String responseString = null; 
     String qualifiedDownloadFilePath = null; 

     try{ 
      // invoke service after setting necessary parameters 
      clientConfig = new ClientConfig(); 
      // clientConfig.register(MultiPartWriter.class); 
      //clientConfig.register(MessageBodyWriter.class); 
      clientConfig.register(MultiPartFeature.class); 


      client = ClientBuilder.newClient(clientConfig); 
      client.property("accept", "application/octet-stream"); 
      webTarget = client.target("http://localhost:8080/EarchivePOC/archive/1"); 

      // invoke service 
      invocationBuilder = webTarget.request(); 
      //   invocationBuilder.header("Authorization", "Basic " + authorization); 
      response = invocationBuilder.get(); 

      // get response code 
      responseCode = response.getStatus(); 
      System.out.println("Response code: " + responseCode);

可能有人請幫助，如果我失去了一些東西。

由於提前，小鷹

試着這麼做：

ByteArrayInputStream bais = response.readEntity(ByteArrayInputStream.class); 
ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
IOUtils.copy(bais, baos); // IOUtils from commons-io
