無法提取響應：沒有合適HttpMessageConverter找到的響應類型[java.util.Map]和內容類型[應用/ JavaScript的]

我消耗的web服務返回未JSONP對象是這樣的：無法提取響應：沒有合適HttpMessageConverter找到的響應類型[java.util.Map]和內容類型[應用/ JavaScript的]

在我的代碼，我調用弗朗這樣：

Object respuesta = restTemplate.getForObject(urlSearch, Map.class, parametros); 
//parametros is of type Map<String, Object>

我獲得以下錯誤：

我一直在努力，包括應用程序/ JavaScript的支持：

MappingJackson2HttpMessageConverter converterJSONP = new MappingJackson2HttpMessageConverter(); 
      converterJSONP.setSupportedMediaTypes(Arrays.asList(new MediaType("application/javascript"))); 
      restTemplate.getMessageConverters().add(converterJSONP);

我以爲會解決問題，但不這樣做，我得到這個錯誤：

Invalid token character '/' in token "application/javascript"

那麼，我可以如何配置我的web應用程序可以con sume返回JSONP對象的Web服務。

在此先感謝！

從@abaghel以下建議，我得到這個錯誤（我想我要創造我自己的HttpMessageConverter）：

嘗試其他客戶端的JSONP像下面。

RestTemplate restTemplate = new RestTemplate(); 
String result = restTemplate.getForObject(url, String.class, params); 
System.out.println(result);

您應該像下面那樣創建MediaType以避免錯誤消息。

MediaType mt = new MediaType("application", "javascript");

您還可以參考SO與應用程序/ JavaScript和jsonp相關的帖子。這篇文章是針對Spring 4的，但你會得到關於jsonp和消息轉換器的信息。

我按照你的意見......但我得到一個新的錯誤。我想我必須實現我自己的HttpMessageConverter。它是否正確？ –

這應該與您爲響應對象使用字符串類型一樣工作。你可以使用restTemplate.getMessageConverters（）檢查你的MessageConverters是否可用於restTemplate？如果您使用Postman進行呼叫，webservice是否會返回正確的響應？ – abaghel

無法提取響應：沒有合適HttpMessageConverter找到的響應類型[java.util.Map]和內容類型[應用/ JavaScript的]
