RestTemplate PATCH request

Question

I have the following definition for PersonDTO:

public class PersonDTO
{
    private String id
    private String firstName;
    private String lastName;
             


        

Answer 1

I have added the below code in the java file. It worked for me.

String url="Your API URL";
RestTemplate restTemplate = new RestTemplate();
HttpClient httpClient = HttpClientBuilder.create().build();
restTemplate.setRequestFactory(new 
HttpComponentsClientHttpRequestFactory(httpClient));    
HttpHeaders reqHeaders = new HttpHeaders();
reqHeaders.setContentType(MediaType.APPLICATION_JSON);
HttpEntity requestEntity = new HttpEntity(requestJson, reqHeaders);
ResponseEntity responseEntity=restTemplate.exchange(url, HttpMethod.PATCH, 
requestEntity, String.class);

Also, need to add the below dependency in the pom.xml file.

    org.apache.httpcomponents
    httpclient
