abc.json文件结构：

[{"name": John, "age": 18}, {"name": Joe, "age": 20}, {"name": Bob, "age": 80}, {"name": Green, "age": 30}]

File jsonFile = ResourceUtils.getFile("classpath:abc.json");

String json = FileUtils.readFileToString(jsonFile);
        JSONArray jsonArray = JSON.parseArray(json);
        for (Object obj : jsonArray) {
            JSONObject jobj = (JSONObject) obj;
            String iso = jobj.getString("***");
        }
