1. 引入gradle依賴：

 // https://mvnrepository.com/artifact/cn.hutool/hutool-all
 implementation group: 'cn.hutool', name: 'hutool-all', version: '5.7.18'

2.進(jìn)行解析轉(zhuǎn)為對(duì)象

    public static void main(String[] args) throws Exception {
        //文件路徑
        String url = "C:\\Users\\Focusmedia\\Downloads\\newjson.json";
        //判斷文件是否存在
       if (!FileUtil.isFile(url)) {
            System.out.println("文件路徑不存在");
            return;
        }
        //解析讀到j(luò)son文件字符串
        String s = FileUtil.readString(url, Charset.forName("UTF-8"));
        //轉(zhuǎn)為對(duì)象
        GalaxyMultiQueryResponse response = JSONUtil.toBean(s, GalaxyMultiQueryResponse.class);
        //數(shù)據(jù)處理
        for (GalaxyMultiQueryResponseDetail datum : response.getData()) {
            System.out.println("\"" + datum.getBuildingId() + "\"");
        }
    }
