spring 如何将XML响应从Roku Tv API转换为JSON？

我试图构建一个使用Roku Tv ECP API命令的应用程序。我试图进行的特定调用获取所有已安装频道的列表，并以XML格式返回。每当我调用此API时，在提取响应时都会收到错误。
下面是我如何进行API调用：

  1. public class ConsumeXMLResponse {
  3.         private RestTemplate restTemplate;
  5.         private final Logger log = LoggerFactory.getLogger(ConsumeXMLResponse.class);
  7.         public ConsumeXMLResponse(RestTemplate restTemplate) {
  8.             this.restTemplate = restTemplate;
  9.         }
  11.         public ResponseEntity<Apps> get() {
  12.             this.restTemplate = new RestTemplateBuilder().build();
  13.             List<HttpMessageConverter<?>> messageConverters = new ArrayList<>();
  14.             MappingJackson2HttpMessageConverter converter = new              MappingJackson2HttpMessageConverter();
  15.             converter.setSupportedMediaTypes(Collections.singletonList(MediaType.ALL));
  16.             messageConverters.add(converter);
  17.             this.restTemplate.setMessageConverters(messageConverters);
  19.             log.info("This worked!");
  20.             return this.restTemplate.getForEntity("http://10.0.0.229:8060/query/apps",
  21.                     Apps.class);
  23.         }
  25.     }

个字符
我试图从响应中重新创建的对象：

  1. @XmlRootElement(name = "apps")
  2. @XmlAccessorType(XmlAccessType.FIELD)
  3. public class Apps {
  5.     @XmlElement(name = "app")
  6.     private List<App> app;
  7. }
  1. @XmlAccessorType(XmlAccessType.FIELD)
  2. public class App {
  4.     @XmlAttribute(name = "id")
  5.     public String id;
  7.     @XmlAttribute(name = "type")
  8.     public String type;
  10.     @XmlAttribute(name = "version")
  11.     public String version;
  13. }

的字符串
下面是在postman中直接调用API时XML的示例：

  1. <?xml version="1.0" encoding="UTF-8" ?>
  2. <apps>
  3.     <app id="tvinput.hdmi3" type="tvin" version="1.0.0">firestick</app>
  4.     <app id="tvinput.hdmi1" type="tvin" version="1.0.0">Xbox</app>
  5.     <app id="tvinput.hdmi2" type="tvin" version="1.0.0">Nintendo Switch</app>
  6.     <app id="tvinput.dtv" type="tvin" version="1.0.0">Live TV</app>
  7.     <app id="12" type="appl" version="5.1.120088002">Netflix</app>
  8.     <app id="61322" type="appl" version="55.2.0">Max</app>
  9.     <app id="13" type="appl" version="14.1.2023092022">Prime Video</app>

我尝试调用返回XML响应的API，然后将其转换为Map到Apps类的Java对象。
这是一个错误：

事实证明，将@JacksonXmlElementWrapper添加到我的应用程序列表属性上的Apps类解决了这个问题。

  1. @JacksonXmlElementWrapper(useWrapping = false)
  2. private List<App> app;

字符串
我也不需要消息转换器。

  1. public Apps getXMLOutput() {
  3.     ResponseEntity<Apps> responseEntity
  4.             = this.restTemplate.getForEntity("http://10.0.0.229:8060/query/apps",
  5.             Apps.class);
  7.     Apps apps = responseEntity.getBody();
  9.     log.info(apps.toString());
  10.     return appsRepository.save(apps);
  11. }
