json - Spring rest 模板无法从 text/html 转换

Question

Spring 休息模板给我带来了以下异常(exception)情况

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

[
 {
  "airlineId": "1",
  "nameAirline": "American Airlines",
  "codeIataAirline": "AA",
  "iataPrefixAccounting": "1",
  "codeIcaoAirline": "AAL",
  "callsign": "AMERICAN",
  "type": "scheduled",
  "statusAirline": "active",
  "sizeAirline": "963",
  "ageFleet": "10.9",
  "founding": "1934",
  "codeHub": "DFW",
  "nameCountry": "United States",
  "codeIso2Country": "US"
 }
]

dto 类

@Data
public class AirlineResponseDTO {
  private String airlineId;
  private String nameAirline;
  private String codeIataAirline;
  private String iataPrefixAccounting;
  private String codeIcaoAirline;
  private String callsign;
  private String type;
  private String statusAirline;
  private String sizeAirline;
  private String ageFleet;
  private String founding;
  private String codeHub;
  private String nameCountry;
  private String codeIso2Country;
}

我怀疑问题出在转换器上。我更改了转换器配置，但这不起作用

@Configuration
public class MvcConfigSupport extends WebMvcConfigurationSupport {
    protected void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        converters.add(converter());
        addDefaultHttpMessageConverters(converters);
    }

    @Bean
    MappingJackson2HttpMessageConverter converter() {
        MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
        converter.setSupportedMediaTypes(Arrays.asList(MediaType.TEXT_HTML));
        return converter;
    }
}

问题解决了。

@Bean
public RestTemplate restTemplate() {
    RestTemplate restTemplate = new RestTemplate();
    MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
    converter.setSupportedMediaTypes(Collections.singletonList(MediaType.TEXT_HTML));
    restTemplate.getMessageConverters().add(converter);
    return restTemplate;
}
