        map.put("claimVoucher",claimVoucherBiz.get(id));
        map.put("items",claimVoucherBiz.getItems(id));
        map.put("records",claimVoucherBiz.getRecords(id));
        DealRecord dealRecord =new DealRecord();
        dealRecord.setClaimVoucherId(id);
        map.put("record",dealRecord);        //通过map返回modelAttribute对应的实体对象
        return "claim_voucher_check";
    }
