Rest-assured. Is it possible to extract value from request json?

Question

I'm getting response this way:

Response response = expect().statusCode(200).given().body(requestBody).contentType("application/json") .when().post("/admin"); String responseBody = response.getBody().asString(); 

I have a json in responseBody:

{"user_id":39} 

Could I extract to string using rest-assured's method only this value = 39?

You can also do like this if you're only interested in extracting the "user_id":

String userId =  given().         contentType("application/json").         body(requestBody). when().         post("/admin"). then().         statusCode(200). extract().         path("user_id"); 

In its simplest form it looks like this:

String userId = get("/person").path("person.userId");
