            System.out.println("调用成功！");
        }else {
            System.out.println("调用失败！");
        }
         
        System.out.println(response.getBody());
}
     
    /**
     * 随机生成订单号

    private static String getoutOrderNo() {
        // TODO Auto-generated method stub
         SimpleDateFormat simpleDateFormat;
         simpleDateFormat = new SimpleDateFormat("yyyyMMddHHmmss");
         Date date = new Date();
         String str = simpleDateFormat.format(date);
         Random random = new Random();
         int rannum = (int) (random.nextDouble() * (999 - 100 + 1)) + 100;// 获取5位随机数
         return str+rannum;// 当前时间
    }
}

如果没有权限，则会返回

调用失败！
{"alipay_fund_coupon_order_agreement_pay_response":{"code":"40004","msg":"Business Failed","sub_code":"ERROR_BALANCE_PAYMENT_DISABLE","sub_msg":"余额支付功能关闭","amount":"0.01","auth_no":"2018010410002001540285562705","operation_id":"20180104462225275402","out_order_no":"20180104145007943","out_request_no":"20180104145007657test","status":"INIT"},"sign":"XXXX"}

由于这边权限过期了，所以没有成功返回的信息，但是代码运行是没问题的 该接口是直接使用的alipayClient.execute(request);，几个红包接口调用的方法都不一样，大家要区别开来，不要混用了。 如有其它问题，欢迎论坛评论留言，如有不足之处也欢迎多多吐槽！！！
