我正在使用一个返回非JSONP对象的Web服务，如下所示：

我正在使用Spring 3.1的RestTemplate对象

这是我的配置

在我的代码中，我以这种方式调用：

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

我收到以下错误：

09:45:22,668 ERROR [stderr] (http-localhost-127.0.0.1-8080-1) org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [java.util.Map] and content type [application/javascript]

我试图加入应用程序/ javascript支持：

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

我认为这会解决问题，但不要，我收到此错误：

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

那么，我如何为我的Web应用程序配置可以使用返回JSONP对象的Web服务。

提前致谢！

根据@abaghel的建议，我收到此错误（我想我必须创建自己的HttpMessageConverter）：

答案 0 :(得分：0)

尝试使用JSONP的rest客户端，如下所示。

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

您应该像下面一样创建MediaType以避免错误消息。

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

您还可以参考与{application / javascript和jsonp相关的SO帖子。这篇文章是针对Spring 4的，但是你将获得有关jsonp和消息转换器的信息。
