Handler层的支持：

@RequestMapping("/pay") public void pay(String id, String money, HttpServletResponse response) throws Exception { //获得初始化的AlipayClient AlipayClient alipayClient = new DefaultAlipayClient(AlipayConfig.gatewayUrl, AlipayConfig.app_id, AlipayConfig.merchant_private_key, "json", AlipayConfig.charset, AlipayConfig.alipay_public_key, AlipayConfig.sign_type); //设置请求参数 AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest(); alipayRequest.setReturnUrl(AlipayConfig.return_url); alipayRequest.setNotifyUrl(AlipayConfig.notify_url); //商户订单号，商户网站订单系统中唯一订单号，必填 String out_trade_no = id; //付款金额，必填 String total_amount = money; //订单名称，必填 String subject = id; //商品描述，可空 String body = ""; alipayRequest.setBizContent("{\"out_trade_no\":\"" + out_trade_no + "\"," + "\"total_amount\":\"" + total_amount + "\"," + "\"subject\":\"" + subject + "\"," + "\"body\":\"" + body + "\"," + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}"); //若想给BizContent增加其他可选请求参数，以增加自定义超时时间参数timeout_express来举例说明 //alipayRequest.setBizContent("{\"out_trade_no\":\""+ out_trade_no +"\"," // + "\"total_amount\":\""+ total_amount +"\"," // + "\"subject\":\""+ subject +"\"," // + "\"body\":\""+ body +"\"," // + "\"timeout_express\":\"10m\"," // + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}"); //请求参数可查阅【电脑网站支付的API文档-alipay.trade.page.pay-请求参数】章节 //请求 String result = alipayClient.pageExecute(alipayRequest).getBody(); //输出 //out.println(result); response.setContentType("text/html"); response.getWriter().println(result); }

支付成功后修改支付状态为1：

@RequestMapping("/paysuccess") public String paysuccess(HttpServletRequest request) throws Exception { //获取支付宝GET过来反馈信息 Map<String, String> params = new HashMap<String, String>(); Map<String, String[]> requestParams = request.getParameterMap(); for (Iterator<String> iter = requestParams.keySet().iterator(); iter.hasNext(); ) { String name = (String) iter.next(); String[] values = (String[]) requestParams.get(name); String valueStr = ""; for (int i = 0; i < values.length; i++) { valueStr = (i == values.length - 1) ? valueStr + values[i] : valueStr + values[i] + ","; } //乱码解决，这段代码在出现乱码时使用 valueStr = new String(valueStr.getBytes("ISO-8859-1"), "utf-8"); params.put(name, valueStr); } boolean signVerified = AlipaySignature.rsaCheckV1(params, AlipayConfig.alipay_public_key, AlipayConfig.charset, AlipayConfig.sign_type); //调用SDK验证签名 //——请在这里编写您的程序（以下代码仅作参考）—— if (signVerified) { //商户订单号 String order_id = new String(request.getParameter("out_trade_no").getBytes("ISO-8859-1"), "UTF-8"); //支付宝交易号 String trade_no = new String(request.getParameter("trade_no").getBytes("ISO-8859-1"), "UTF-8"); //付款金额 String total_amount = new String(request.getParameter("total_amount").getBytes("ISO-8859-1"), "UTF-8"); //实现支付状态的修改,改为已支付,paystate=1 orderService.paySuccess(order_id); return "redirect:/client/paysuccess.jsp"; // out.println("trade_no:"+trade_no+"<br/>out_trade_no:"+out_trade_no+"<br/>total_amount:"+total_amount); } else { return "redirect:/client/fail.jsp"; // out.println("验签失败"); } } <update id="updatePayState"> update orders set paystate = 1 where id = #{order_id} </update>
