调用修补程序请求的Spring Resttemplate exchange方法

Question

我有一个带有spring框架的Java8应用程序。我们需要从应用程序中使用REST调用补丁操作。

代码片段如下：

import com.xyz.myobject.ResponseAdmission;
import com.xyz.myobject.RequestAdmission;

@Repository
public class AdmissionRepository {

   @Autowired
   private RestTemplate restTemplate;

   public ResponseObject updateAdmission(RequestAdmission requestAdmission, String admissionId) {

   UriBuilder uriBuilder =  UriBuilder.fromUri("https://admissionportal.com").path("admission").path("admissionId="+admissionId);

   HttpEntity<RequestAdmission> admissionEntity = new HttpEntity<>(requestAdmission, this.getHeaders);

   ResponseEntity<ResponseAdmission> responseEntity = this.restServiceESBSupport.exchange(uriBuilder.build(), HttpMethod.PATCH, admissionEntity , ResponseAdmission.class);

   return responseEntity.getBody();

}

public MultiValueMap<String, String> getHeaders() {
        MultiValueMap<String, String> headers = new LinkedMultiValueMap<>();
        headers.add("Accept", "application/xml");
        headers.add("Content-Type", "application/xml");
        return headers;
    }

}

ByteArrayHttpMessageConverter,
StringHttpMessageConverter,
ResourceHttpMessageConverter,
SourceHttpMessageConverter,
AllEncompassingFormHttpMessageConverter,
Jaxb2RootElementHttpMessageConverter,
MappingJackson2HttpMessageConverter

this.restTemplate.getMessageConverters().add(new Jaxb2RootElementHttpMessageConverter());

请指教。

您可以将自己的XML创建为字符串，并在您的请求中使用它，如下所示：

@Repository
public class AdmissionRepository {

   @Autowired
   private RestTemplate restTemplate;

   public ResponseObject updateAdmission(RequestAdmission requestAdmission, String admissionId) {

   UriBuilder uriBuilder =  UriBuilder.fromUri("https://admissionportal.com").path("admission").path("admissionId="+admissionId);
   String xmlString = // create an actual valid XML string with all the <tag>value</tag> and the whole structure.
   HttpEntity<String> admissionEntity = new HttpEntity<>(xmlString, this.getHeaders);

   ResponseEntity<ResponseAdmission> responseEntity = this.restServiceESBSupport.exchange(uriBuilder.build(), HttpMethod.PATCH, admissionEntity , ResponseAdmission.class);

   return responseEntity.getBody();

}
