两个实体类

        // 该笔订单允许的最晚付款时间，逾期将关闭交易。取值范围：1m～15d。m-分钟，h-小时，d-天，1c-当天（1c-当天的情况下，无论交易何时创建，都在0点关闭）。 该参数数值不接受小数点， 如 1.5h，可转换为 90m。
        String timeout_express = "1c";

    }

    }

        System.out.println("请求支付宝查询接口返回的结果为:"+response.getBody());

主要方法

//支付
    @RequestMapping(value = "addOrder", produces = "text/html; charset=UTF-8")
    @ResponseBody
    public String goPay(Torder torder) throws AlipayApiException {
        String order = AlibabapayGateWayUtils.createOrder("订单号", "总金额"   ,"商品名称", "描述");
        return order;
    }
