Get Json object from Itis with spring boot - json

Question

I try to get a Json object from Itis Webservice (https://www.itis.gov/ITISWebService/jsonservice/getHierarchyUpFromTSN?tsn=164282).
I use the following class to store the Json object:
public class Genus {
#JsonProperty("tsn")
private int tsn;
#JsonProperty("taxonName")
private String taxonName;
public Genus() {
super();
}
public int getTsn() {
return tsn;
}
public void setTsn(int tsn) {
this.tsn = tsn;
}
public String getCombinedName() {
return taxonName;
}
public void setCombinedName(String taxonName) {
this.taxonName = taxonName;
}
#Override
public String toString() {
return "Genus [tsn=" + tsn + ", taxonName=" + taxonName + "]";
}
}
My main method:
public static void main(String[] args) {
RestTemplate restTemplate = new RestTemplate();
Genus quote = restTemplate.getForObject("https://www.itis.gov/ITISWebService/jsonservice/getHierarchyUpFromTSN?tsn=164282", Genus.class);
System.out.println(quote.toString());
}
As result I get the following exception:
Exception in thread "main"
org.springframework.web.client.RestClientException: Could not extract
response: no suitable HttpMessageConverter found for response type
[class de.aquaristikguru.taxonomy.itisObjects.Genus] and content type
[text/json;charset=ISO-8859-1
How can I fixed it?
