使用java迭代JSON响应中出现的最后一个值

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonIterator {
    public static void main(String[] args) {
        String jsonResponse = "{\"name\":\"John\",\"age\":30,\"city\":\"New York\"}";

        ObjectMapper objectMapper = new ObjectMapper();
        try {
            JsonNode jsonNode = objectMapper.readTree(jsonResponse);
            iterateJson(jsonNode);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static void iterateJson(JsonNode jsonNode) {
        if (jsonNode.isObject()) {
            jsonNode.fields().forEachRemaining(entry -> {
                String key = entry.getKey();
                JsonNode value = entry.getValue();

                if (value.isObject()) {
                    iterateJson(value);
                } else {
                    System.out.println("Key: " + key + ", Value: " + value);
                }
            });
        }
    }
}
