提问by aayushkr
I am trying capture the response of an HTTP request made by my java client code. The response has a content-type of application/pdf. In the logs I can see that the server sent a response in
我正在尝试捕获由我的 java 客户端代码发出的 HTTP 请求的响应。响应的内容类型为application/pdf。在日志中，我可以看到服务器在
Object result = getRestTemplate().postForObject(urlString, formDataHttpEntity, returnClassObject, parametersMapStringString);
and I get the following JUnit error:
我收到以下 JUnit 错误：
org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [java.lang.Object] and content type [application/pdf]
org.springframework.web.client.RestClientException：无法提取响应：没有找到适合响应类型 [java.lang.Object] 和内容类型 [application/pdf] 的 HttpMessageConverter
What do I need to do to get past this? My ultimate goal is to take this in a byte[]and push it in a DB table field of blob type
我需要做什么才能度过难关？我的最终目标是将其放入 abyte[]并将其推送到blob 类型的数据库表字段中
Note: I get the following response header from the server
注意：我从服务器得到以下响应头
HTTP/1.1 200 OK Cache-Control: max-age=0,must-revalidate
Content-Disposition: attachment; filename="Executive Summary.PDF"
Content-Type: application/pdf
HTTP/1.1 200 OK Cache-Control: max-age=0,must-revalidate

Thanks Thomas it worked.
谢谢托马斯，它奏效了。
I added ByteArrayHttpMessageConverter to the RestTemplate and it worked.
我将 ByteArrayHttpMessageConverter 添加到 RestTemplate 并且它起作用了。
Code I added:
我添加的代码：
ByteArrayHttpMessageConverter byteArrayHttpMessageConverter = new ByteArrayHttpMessageConverter();
List<MediaType> supportedApplicationTypes = new ArrayList<MediaType>();
MediaType pdfApplication = new MediaType("application","pdf");
supportedApplicationTypes.add(pdfApplication);
byteArrayHttpMessageConverter.setSupportedMediaTypes(supportedApplicationTypes);
List<HttpMessageConverter<?>> messageConverters = new ArrayList<HttpMessageConverter<?>>();
messageConverters.add(byteArrayHttpMessageConverter);
restTemplate = new RestTemplate();
restTemplate.setMessageConverters(messageConverters);
Object result = getRestTemplate().getForObject(url, returnClass, parameters);
byte[] resultByteArr = (byte[])result;
