# JSONQuery 
[![Maven Central](https://maven-badges.herokuapp.com/maven-central/me.kagura/JSONQuery/badge.svg)](https://maven-badges.herokuapp.com/maven-central/me.kagura/JSONQuery)

Easier to use Gson to parse json.

### Example：
~~~java
public void Test() throws TypeNotMismatchException, FieldNotExistException {
        String json = "" +
                "{\n" +
                "  \"errno\": 0,\n" +
                "  \"errmsg\": 成功,\n" +
                "  \"user\": \"{\\\"user_id\\\":643361255,\\\"user_name\\\":\\\"鹞之神乐\\\",\\\"user_sex\\\":1,\\\"user_status\\\":1}\",\n" +
                "  \"comment_info\": [\n" +
                "    {\n" +
                "      \"thread_id\": \"5504460056\",\n" +
                "      \"post_id\": \"116776960983\",\n" +
                "      \"comment_id\": \"116857893053\"\n" +
                "    },\n" +
                "    {\n" +
                "      \"thread_id\": \"5504460056\",\n" +
                "      \"post_id\": \"116776960983\",\n" +
                "      \"comment_id\": \"116858057626\"\n" +
                "    },\n" +
                "    {\n" +
                "      \"thread_id\": \"5504460056\",\n" +
                "      \"post_id\": \"116776960983\",\n" +
                "      \"comment_id\": \"116880757453\"\n" +
                "    }\n" +
                "  ],\n" +
                "  \"data\": {\n" +
                "    \"comment_list\": {\n" +
                "      \"116776891765\": {\n" +
                "        \"comment_num\": 3,\n" +
                "        \"comment_list_num\": 4\n" +
                "      },\n" +
                "      \"116776960983\": {\n" +
                "        \"comment_num\": 4,\n" +
                "        \"comment_list_num\": 4\n" +
                "      }\n" +
                "    }\n" +
                "  }\n" +
                "}";

        //获取根元素errno
        JsonResult jsonResult = JSONQuery.select(json, "errno");
        //获取根元素errno，并转换为int
        int errno = jsonResult.getAsInt();
        //获取根元素data中的comment_list
        jsonResult = JSONQuery.select(json, "data > comment_list");
        //正则过滤出属性数组，针对一部分拿对象当数组用的情况
        jsonResult = JSONQuery.select(json, "data > comment_list > [\\d+]");
        //获取数组指定位置的元素
        jsonResult = JSONQuery.select(json, "comment_info > [2]");
        //获取数组指定位置的元素 负数坐标
        jsonResult = JSONQuery.select(json, "comment_info > [-1]");
        //针对某个字符串属性的值又是个json字符串的情况
        jsonResult = JSONQuery.select(json, "user > user_name");
        //jsonResult作为参数替代json字符串
        JsonResult data = JSONQuery.select(json, "data");
        jsonResult = JSONQuery.select(data, "comment_list");
