我正努力从我的Google Custom Search API查询中返回的JSON中找到创建JSON对象的方法。我目前使用下面的代码来执行搜索和搜索查询的结果作为字符串返回：如何从Google自定义搜索API创建JSON对象？
URL url = new URL(
"https://www.googleapis.com/customsearch/v1?key=" + key + "&cx=" + cx + "&q=" + qry + "&alt=json&queriefields=queries(request(totalResults))");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.setRequestProperty("Accept", "application/json");
BufferedReader br = new BufferedReader(new InputStreamReader(
(conn.getInputStream())));
System.out.println("Output from Server .... \n");
while ((output = br.readLine()) != null) {
System.out.println(output);
}
如何解析JSON使用杰克逊2 Java对象？我只主要想保留图像链接和描述。我如何使用Jackson 2来做到这一点？还是我需要使用别的东西？我的JSON响应的
一部分下面贴（整件事是巨大的）：
