首先,我已经在stackoverflow中阅读了与此主题相关的所有问题,但我找不到解决方案.我已经做了好几天了.

我有这个restFull网络应用程序用spring mvc构建.当我尝试检索用户时,我收到此错误:

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]

请求永远不会到达服务器,因此问题不是响应内容类型,因为没有响应.所以我在那里失去了.我在这里展示我的课程和配置,如果遗漏了一些信息,请告诉我,我会更新问题.谢谢!

客户控制器:

@Controller
public class HomeController extends GenericAbstractController{

@RequestMapping(value = "/home", method = RequestMethod.GET)
public String getHome(HttpServletRequest request, Model model) {
    Principal userPrincipal = request.getUserPrincipal();

    List<MediaType> acceptableMediaTypes = new ArrayList<MediaType>();
    acceptableMediaTypes.add(MediaType.APPLICATION_XML);

    HttpHeaders headers = new HttpHeaders(); …
