public Result insertAndItem(Water_booklet booklet, List<Water_booklet_item> items) {
        String[] userId = booklet.getUserId().split(",");   //针对多用户进行分割
        for (int i = 0;i < userId.length;i++){
            booklet.setUserId(userId[i]);
            if(i == 0){   //把第一个抄表人的信息存入抄表册
                // 保存抄表册主信息
                booklet = this.insert(booklet);
            }else {
