How to convert HttpResponse to Class in Java with HttpClient?

Question

I am using the Java HttpClient (java.net.http) and I am sending a GET request.

The response I get is a JSON String of the class "UserDto".

HttpResponse send = httpClient.send(accept, HttpResponse.BodyHandlers.ofString());

I don't want to receive my response as a string but convert it directly into a "UserDto" object.

You can use gson package to map the string to your UserDto class like the following:

String result;  // JSON String of the class "UserDto".
UserDto userDto = gson.fromJson(result, UserDto.class);
return userDto;

jackson is also an option but I prefer gson as its really simple to map with.
