spring - 如何在应用程序/xml中接受假装响应

问题描述

我正在调用以 XML 格式返回响应的第 3 方 API。由于我没有创建任何 POJO 来在我使用java.lang.Object的消费者服务中保持响应。

我收到以下错误。

org.springframework.web.client.UnknownContentTypeException: Could not extract response: no suitable HttpMessageConverter found for response type [class java.lang.Object] and content type [application/xml]
    at org.springframework.web.client.HttpMessageConverterExtractor.extractData(HttpMessageConverterExtractor.java:126) ~[spring-web-5.2.10.RELEASE.jar:5.2.10.RELEASE]
    at org.springframework.cloud.openfeign.support.SpringDecoder.decode(SpringDecoder.java:59) ~[spring-cloud-openfeign-core-2.2.5.RELEASE.jar:2.2.5.RELEASE]
    at org.springframework.cloud.openfeign.support.ResponseEntityDecoder.decode(ResponseEntityDecoder.java:62) ~[spring-cloud-openfeign-core-2.2.5.RELEASE.jar:2.2.5.RELEASE]

我的假客户端代码

@FeignClient(value = "SERVICE", url = "https://goog.dummyservice/api1/v1", decode404 = true)
public interface UserFeign {

    @GetMapping(value = "/docs/{profile}/{protocol}", consumes = MediaType.APPLICATION_XML_VALUE)
    Object getUserData(@RequestHeader("Authorization") String token,
                         @PathVariable("profile") String profile,
                         @PathVariable("protocol") String protocol);
}

我想知道如何通过 feign 来保存 XML 响应。

解决方案

FeignClientConfiguration.java

@Configuration
@RequiredArgsConstructor
public class FeignClientConfiguration {

private final ObjectFactory<HttpMessageConverters> messageConverters;

@Bean
public Encoder feignFormEncoder() {
    return new FormEncoder(new SpringEncoder(messageConverters));
}

/*@Bean
public Decoder feignDecoder() {
    MappingJackson2XmlHttpMessageConverter c = new MappingJackson2XmlHttpMessageConverter();
    ObjectFactory<HttpMessageConverters> objectFactory = () ->new HttpMessageConverters(c);
    return new ResponseEntityDecoder(new SpringDecoder(objectFactory));
}*/

}

咨询客户端.java

    @FeignClient(url = "${api.serpro.url}",
            name = "name",
            configuration = FeignClientConfiguration.class)
    public interface ConsultaClient {

    @PostMapping(consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE, produces = MediaType.APPLICATION_XML_VALUE)
    @Headers("Content-Type: application/x-www-form-urlencoded")
    List<DocumentoDTO> getData(ParamsDTO params);
}
