Map Json to POJO class using Rest Template exchange method - json

Question

This is my POST request to an API
ResponseEntity<String> result = rt.exchange(url, HttpMethod.POST, httpEntity, String.class);
The response i am getting is below
{
"headers": {
"Cache-Control": [
"no-store"
],
"Content-Type": [
"application/json;charset=UTF-8"
],
"Date": [
"Thu, 20 Jun 2019 12:50:08 GMT"
],
"Pragma": [
"no-cache"
],
"Server": [
"val"
],
"X-Content-Type-Options": [
"nosniff"
],
"X-Frame-Options": [
"DENY"
],
"X-Xss-Protection": [
"1; mode=block"
],
"Content-Length": [
"331"
]
},
"body": {
"access_token": "token_value,
"scope": "KYC",
"token_type": "bearer",
"expires_in": 49900,
"jti": "jti_val"
},
"statusCode": "OK",
"statusCodeValue": 200
}
I need to get extract
access_token,scope,token_type,statusCodeValue
So what should be structure of my POJO class to map the response ?Or how can i get the values from JSON for those fields ?
ResponseEntity<PojoClass> result = rt.exchange(url, HttpMethod.POST, httpEntity, PojoClass.class);

Answer 1

Body can get through the snippet posted above and status code can be retrieved using "response.getStatus()"

Answer 2

try this:updated
ResponseEntity<Response> response = rt.exchange(url, HttpMethod.POST, httpEntity, Response.class);
Class definition:
Body Class:
public class Body implements Serializable{
private String access_token;
private String scope;
private String token_type;
private long expires_in;
private String jti;
//standard getters and setters
}
Response class:
#JsonIgnoreProperties(ignoreUnknown = true)
public class Response implements Serializable{
private String statusCode;
private int statusCodeValue;
private Body body;
//standard getters and setters
}
Now:
you should access your desired values using their respective getters method.
like:
String token=response.getBody.getAccessToken();
String statusCode= respnse.getStatusCode();
