java动态读取json文件插入到数据库

@GetMapping("getJson")
    public Result getJson(String id) {
        System.out.println(DateUtil.formatTime(new Date()));
        HashMap<String, Object> expertInfoQueryMap = new HashMap<>();
        FileReader fileReader = new FileReader("G:\\BaiduNetdiskDownload\\医疗软件\\医疗代码\\02-尚医通后端代码\\yygh_parent\\service\\service_cmn\\src\\main\\java\\com\\atguigu\\yygh\\cmn\\controller"  + "/testsql.json");
        String result = fileReader.readString();
        cn.hutool.json.JSONObject jsonObject = JSONUtil.parseObj(result);
        Set<String> strings = jsonObject.keySet();
      //针对读取的json文件进行强制转换
        String ziudan = (String) jsonObject.get("ziudan");
        String biaoming = (String) jsonObject.get("biaoming");
        List<Map<String, Object>> date = (List<Map<String, Object>>) jsonObject.get("date");
        Map<String, Object> map = date.get(0);
        //获取map的所有key进行动态拼接
        Set<String> keySet = map.keySet();
        String ss="";
        for (String s : keySet) {
            ss+="#{map."+s+"},";
        }
        //截取指定的字符串,并进行拼接
        String substring = ss.substring(0, ss.lastIndexOf(","));
        String substring1= "("+substring+ ")";
        System.out.println(substring1);

        dictService.getJson(ziudan,biaoming,date,substring1);
        // String dictName = dictService.getDictName("",value);
        return Result.ok(expertInfoQueryMap);
    }

  <insert id="add3">
        insert into ${biaoming}(${ziudan}) values
        <foreach collection="date" item="map" separator=",">
           ${substring1}
        </foreach>
    </insert>

json文件结构 得加入糊涂工具类
