web沙箱支付宝功能（详细）非maven版

今天简单实现下支付宝的沙箱支付，萌新，还不会用maven，还是手动导入的jar包。jar包和代码大部分来自支付宝演示demo，我下面贴上下载链接

链接：支付宝演示demo

首先下载支付宝开发平台软件，生成密匙
支付宝沙箱链接
点击链接然后登陆，开启那个自定义密匙，



这里输入前面生成的公匙

生成之后一套公共的配置数据就全了。
配置一下公共can’shucanshu

public class AlipayConfig {
    // 商户appid
    public static String APPID = "2021000119624409";
    // 私钥 pkcs8格式的

}

这里通过servlet调用支付宝sdk

       String addaccount=request.getParameter("addaccount");//这是我从前端获取的数据，可以不写
            String ordernumber= UtilId.getGUID();


            int addaccount1=Integer.parseInt(addaccount);
            HttpSession session=request.getSession();
            Customer customer=(Customer) session.getAttribute("customer");
            String id_name=customer.getId_name();
            System.out.println(addaccount);
            request.setCharacterEncoding("utf-8");
            response.setContentType("text/html;charset=utf-8");
            //初始化
            AlipayClient alipayClient = new DefaultAlipayClient(AlipayConfig.URL,
                    AlipayConfig.APPID,
                    AlipayConfig.RSA_PRIVATE_KEY,
                    AlipayConfig.FORMAT,
                    AlipayConfig.CHARSET,
                    AlipayConfig.ALIPAY_PUBLIC_KEY,
                    AlipayConfig.SIGNTYPE);
            //创建API对应的request
            AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest();
            //在公共参数中设置回跳和通知地址
            alipayRequest.setReturnUrl(AlipayConfig.return_url);
            alipayRequest.setNotifyUrl(AlipayConfig.notify_url);
            System.out.println(1);
                 //填充业务参数

            //必填
            //商户订单号，需保证在商户端不重复
            String out_trade_no = ordernumber;
            //销售产品码，与支付宝签约的产品码名称。目前仅支持FAST_INSTANT_TRADE_PAY
            String product_code = "FAST_INSTANT_TRADE_PAY";
            //订单总金额，单位为元，精确到小数点后两位，取值范围[0.01,100000000]。
            String total_amount =addaccount;
            //订单标题
            String subject = "账户充值";

            //选填
            //商品描述，可空
            String body = "商品描述";
            System.out.println(2);

            alipayRequest.setBizContent("{" +
                    ""out_trade_no":"" + out_trade_no + ""," +
                    ""product_code":"" + product_code + ""," +
                    ""total_amount":"" + total_amount + ""," +
                    ""subject":"" + subject + ""," +
                    ""body":"" + body + ""}");
            //请求
            String form = "";
            try {
                form = alipayClient.pageExecute(alipayRequest).getBody();//调用SDK生成表单

            } catch (AlipayApiException e) {
                e.printStackTrace();
                response.getWriter().write("捕获异常出错");
                response.getWriter().flush();
                response.getWriter().close();
            }
            response.setContentType("text/html;charset=" + AlipayConfig.CHARSET);
            response.getWriter().write(form);//直接将完整的表单html输出到页面
            response.getWriter().flush();
            response.getWriter().close();
z

        }

至于异步通知，同步通知的信息根据自己项目需求来验证。
