春季休息模板引发了以下异常

org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [class [Lcom.flightsms.core.dto.AirlineResponseDTO;] and content type [text/html;charset=UTF-8]

这是我的 json 响应

  "iataPrefixAccounting": "1",
  "codeIcaoAirline": "AAL",

  "founding": "1934",
  "codeHub": "DFW",
  "nameCountry": "United States",
  "codeIso2Country": "US"
 }
]

dto类

@Data
public class AirlineResponseDTO {
  private String airlineId;

我的代码：

MultiValueMap<String, String> headers = new LinkedMultiValueMap<String, String>();
headers.add("Content-Type", "application/camiant-msr-v2.0+xml");

HttpEntity<?> entity = new HttpEntity<Object>(headers);
