How to correctly write a JSON string from a request?

Question

Java

Hello.
Tell me please.
There is a GET request, in response to which there is a JSON string. What is needed to correctly write this response into an object - what class, and what deserializer?
Request:
api.fixer.io/latest?callback=?
Thank you very much in advance!

Answer 1

For this to be correct JSON, you need a call to api.fixer.io/latest
Take GSON

public static void main(final String[] args) {
    final Gson gson = new Gson();

    final Response response = gson.fromJson("{base: EUR, date:1, rates:{AUD: 1.3762,BGN: 1.9558}}", Response.class);
    System.out.println(response);
  }

  static class Response {
    String base;
    String date;
                Map<String, String> rates;
    @Override
    public String toString() {
      return "Response [base=" + base + ", date=" + date + ", rates=" + rates + "]";
    }
  
  }

Answer 2

Everything turned out to be simple. It was necessary to make a custom deserializer)
