这种情况要怎样将数据返回

这种情况下要怎么将数据返回给askbillBodyDataTable

protected void assembleDatatable() {
        askbillHeadDataTable.set(askbillhead1);
        askbillHeadDataTable.setSelect(new Integer[]{0});
        askbillBodyDataTable.set(askbillbodys1);
        askbillBodyDataTable.setTotalPages(1);//songpeng 增加物料规格和型号（根据物料id--product_id查询）;产品描述（product_desc）、表体备注（bmemo）；
        askbillBodyDataTable.setPageIndex(0);
        askbillBodyDataTable.setPageSize(1);
        priceDataTable.set(compareInfos1);//承兑价，现金价，报价说明，交货期
        priceDataTable.setTotalPages(1);
        priceDataTable.setPageIndex(0);
        priceDataTable.setPageSize(1);
        if (talksDataTable != null && quotationOffers1 != null) {
            talksDataTable.set(quotationOffers1.toArray(new QuotationOffer[0]));
            talksDataTable.setSelect(new Integer[]{0});
        }
        //上期成交价(含税)
        //askbillBodyDataTable-rows-data-extFields-historySupplyPrice- LASTPRICE
        Row[] rows = askbillBodyDataTable.getRows();
        for (Row str : rows) {
            Map < String, Field > data = str.getFields();
            Field extFields = data.get("extFields");
            HashMap value = (HashMap) extFields.getValue();
            HashMap historySupplyPrice = (HashMap) value.get("historySupplyPrice");
            Double lastprice1 = (java.lang.Double) historySupplyPrice.get("LASTPRICE");
            double d = lastprice1;
            int d2 = (int) d;
            String s1 = String.valueOf(d);
            if (s1.contains(".") && d2 != d) {
                int i = s1.indexOf(".");
                for (int j = i; j < s1.length() - 1; j++) {
                    int lastIndex = s1.charAt(s1.length() - 1);
                    int io = s1.lastIndexOf("0");
                    if (lastIndex == io) {
                        s1 = s1.substring(0, s1.length() - 1);
                    }
                }
            } else {
                s1 += "0";
            }
            logger.info("s1:" + s1);
        }

将你这段代码封装在一个json数组里，然后返回

for (Row str : rows) {
            Map < String, Field > data = str.getFields();
            Field extFields = data.get("extFields");
            HashMap value = (HashMap) extFields.getValue();
            HashMap historySupplyPrice = (HashMap) value.get("historySupplyPrice");
            Double lastprice1 = (java.lang.Double) historySupplyPrice.get("LASTPRICE");
            double d = lastprice1;
            int d2 = (int) d;
            String s1 = String.valueOf(d);
            if (s1.contains(".") && d2 != d) {
                int i = s1.indexOf(".");
                for (int j = i; j < s1.length() - 1; j++) {
                    int lastIndex = s1.charAt(s1.length() - 1);
                    int io = s1.lastIndexOf("0");
                    if (lastIndex == io) {
                        s1 = s1.substring(0, s1.length() - 1);
                    }
                }
            } else {
                s1 += "0";
            }
            logger.info("s1:" + s1);

没太看懂，askbillBodyDataTable这个是你定义的全局变量么，你想把for循环里的数据给这个变量，这个变量需要有个属性，askbillBodyDataTable.set属性（s1）

askbillBodyDataTable 是个啥.我看你有getRow方法.那你把其他值塞进去呗

askbillBodyDataTable是什么啊

把void改为AskbillBodyDataTable，之后再返回你set的那些数据return askbillBodyDataTable，或者也可以不用返回，你在哪里用得到askbillBodyDataTable，就在哪里调用你现在写这个assembleDatatable()方法就行

看不懂

askbillBodyDataTable 可以用getRow

你是前后端分离吗
