关于枚举的使用心得，直接上代码

    public static Map<String,Object> calculateParam(List<QRecord> qRecordList){
        return ListUtils.toMap(qRecordList,q -> q.field.name()+" "+q.opt.operator , q -> q.val);
    }
    
    public static void main(String[] args) {
        enum GoodsField{ price, name, category }

        System.out.println(JSONUtil.toJsonPrettyStr(
            calculateParam(
                List.of(

                    new QRecord(GoodsField.price,Opt.greater_equal,129.9D),
                    new QRecord(GoodsField.price,Opt.less_equal,299.9D)
                )
