java - RestClientException Could not extract response: no suitable HttpMessageConverter found for response type -

i have following pojo:

@data @builder @noargsconstructor @allargsconstructor public class kostenpflichtigebuchung {     private string buchungzahlungsid;      private string warenkorbid;      private string pseudocardpan;      private zahlungsmittel zahlungsmittel;      private string landkreditkarteninhaber;      private string namekreditkarteninhaber;      private string touchpointid;      private string vertriebspartnerid;      private kundendaten kundendaten;      private fulfillmentart fulfillmentart;      private final list<reisender> reisenderlist = new arraylist<>();      @jsonignore     private map<string, object> payload;      @jsonanygetter     public map<string, object> getpayload() {         return payload;     }      @jsonanysetter     public void setpayload(string name, object value) {          if (payload == null) {             payload = new hashmap<>();         }         payload.put(name, value);     } } 

when execute cucumber test on it, following exception:

org.springframework.web.client.restclientexception: not extract response: no suitable httpmessageconverter found response type [class de.db.vendo.bue.buchung.model.kostenpflichtigebuchung] , content type [application/json;charset=utf-8]      @ org.springframework.web.client.httpmessageconverterextractor.extractdata(httpmessageconverterextractor.java:109)     @ org.springframework.web.client.resttemplate$responseentityresponseextractor.extractdata(resttemplate.java:917)     @ org.springframework.web.client.resttemplate$responseentityresponseextractor.extractdata(resttemplate.java:901)     @ org.springframework.web.client.resttemplate.doexecute(resttemplate.java:655)     @ org.springframework.web.client.resttemplate.execute(resttemplate.java:613)     @ org.springframework.web.client.resttemplate.exchange(resttemplate.java:531)
