no suitable HttpMessageConverter found for response type
You could also simply tell your RestTemplate
to accept all media types:
@Bean
public RestTemplate restTemplate() {
final RestTemplate restTemplate = new RestTemplate();
List<HttpMessageConverter<?>> messageConverters = new ArrayList<>();
MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
converter.setSupportedMediaTypes(Collections.singletonList(MediaType.ALL));
messageConverters.add(converter);
restTemplate.setMessageConverters(messageConverters);
return restTemplate;
}
From a Spring point of view, none of the HttpMessageConverter
instances registered with the RestTemplate
can convert text/html
content to a ProductList
object. The method of interest is HttpMessageConverter#canRead(Class, MediaType)
. The implementation for all of the above returns false
, including Jaxb2RootElementHttpMessageConverter
.
Since no HttpMessageConverter
can read your HTTP response, processing fails with an exception.
If you can control the server response, modify it to set the Content-type
to application/xml
, text/xml
, or something matching application/*+xml
.
If you don't control the server response, you'll need to write and register your own HttpMessageConverter
(which can extend the Spring classes, see AbstractXmlHttpMessageConverter
and its sub classes) that can read and convert text/html
.
