Answer 1

首先，使用JSON字符串创建一个POJO类：

http://www.jsonschema2pojo.org/

然后，创建POJO类的实例。现在，使用GSON，您可以在实例中设置值。最后，您可以使用getter方法获取值

例如。

Usermodel usermodel = new Gson().fromJson(<JSON string>, UserModel.class);

Usermodel是我的POJO类。

Please check below:

    @Test
    public void getlikecount() {
        String JSON = "{\r\n" + 
                "    \"count\": 1,\r\n" + 
                "    \"next\": null,\r\n" + 
                "    \"previous\": null,\r\n" + 
                "    \"results\": [\r\n" + 
                "        {\r\n" + 
                "            \"likecount\": 0,\r\n" + 
                "            \"unlikeCount\": 0,\r\n" + 
                "            \"shareCount\": 0,\r\n" + 
                "            \"i_id\": 297,\r\n" + 
                "            \"p_id\": 297,\r\n" + 
                "            \"name\": \"Airport  runways  columbia  hon\",\r\n" + 
                "            \"description\": \"Airport  runways  columbia  hongkong  aviation  airplanes  aeroplanes\",\r\n" + 
                "            \"c_id\": 1,\r\n" + 
                "            \"status_id\": 1,\r\n" + 
                "            \"source_id\": 149,\r\n" + 
                "            \"date_created\": null,\r\n" + 
                "            \"parentinfograph\": \"Staffing insurance  liability  \",\r\n" + 
                "            \"internal_url\": \"http://167.99.86.81:8000/media/DQ297.jpg\",\r\n" + 
                "            \"external_url\": \"http://www.aertecsolutions.com/wp-content/uploads/2017/03/Infographic-Runway-ENG.jpg\",\r\n" + 
                "            \"mt_id\": 1,\r\n" + 
                "            \"mtcode\": \"Business\"\r\n" + 
                "        }\r\n" + 
                "    ]\r\n" + 
                "}";

         JsonPath jsonpath = new JsonPath(JSON);
         System.out.println("value of key->likecount: "+jsonpath.getString("results.likecount[0]"));



    }

Output: value of key->likecount: 0
