I want to extract json object with restassured, and response is generic like:

@Data
public class ExtractBase<T> {
    private Class<T> result; // here I can expect different classes 
    private String targetUrl;
    private Boolean success;
    private String error;
    private Boolean unAuthorizedRequest;
    private Boolean __abp;

}

and I want extract it and get result each time with different class:

.extract().body().as(ExtractBase.class).getResult(); // and here I want to have possibility to choose class which should be exctracted depends on my request

I have tried to use TypeToken but with no result :(

any tips for extracting generic classes from JSON responses?

Use ObjectMapper to map from Objects response to custom type. Example objectMapper.readValue(json.getBoody(), YourType.class) Remember, that objectMaper mustbe register module on methot objectMaper

private final ObjectMapper mapper = new ObjectMapper().findAndRegisterModules();

and your response shouldby

private T result;  - witout "class"
