FastJSON解析JSON字符串数据

 需要解析的JSON数据如下：

解析代码：

 public static void main(String[] args) {

        String result = "{\"msg\":\"success\",\"code\":0,\"data\":[{\"invoice_code\":\"3700194130\",\"total_amount\":22090.39,\"total_amount_excluding_tax\":20266.41,\"total_tax_amount\":1823.98}],\"count\":1}";

        JSONObject obj = JSONObject.parseObject(result);
        if (obj == null || !"0".equals(ObjectUtils.nullSafeToString(obj.get("code")))) {
            System.out.println("查询失败");
        }
        if(org.apache.commons.lang.StringUtils.isNotBlank(obj.getString("data"))){
            JSONArray list = JSON.parseArray(obj.getString("data"));
            for (int i = 0; i < list.size(); i++) {
                JSONObject object =  JSON.parseObject(org.apache.commons.lang.ObjectUtils.toString(list.get(i))) ;
                System.out.println(object.getString("invoice_code"));
                System.out.println(object.getString("total_amount"));
                System.out.println(object.getString("total_amount_excluding_tax"));
                System.out.println(object.getString("total_tax_amount"));
            }
        }
        System.out.println("解析结束");
    }
