no suitable HttpMessageConverter found for response type [com.src.model.UserDTO] and content type [text/html;charset=UTF-8] - rest

Question

first of all, i've already read all questions related with this topic in stackoverflow, but i can't find the solution. I have been working on this for days.
I have this restFull web app built with spring mvc. When i try to retrieve a User i get this error:
org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [com.src.model.UserDTO] and content type [text/html;charset=UTF-8]

The request never reach the server, so the problem isn't the response content-type, because there is no response. So i am loss there. I show here my classes and configs, if some info is missed, please let me know, and i will update the question. Thanks!

ResponseEntity<UserDTO> result = restTemplate.exchange("http://localhost:8080/rideon/users/{id}",
HttpMethod.GET, entity, UserDTO.class, userPrincipal.getName());

return "home";
}

Answer 1

Ok I finally found the problem. The response is actually an html error page generated by a wrong security configuration. Indeed the above code seems to be ok. Thanks!
