1.添加依赖
<dependency> <groupId>com.alipay.sdk</groupId> <artifactId>alipay-sdk-java</artifactId> <version>3.7.4.ALL</version></dependency> 2.进行配置基本的支付信息
package com.bookstore.utils; import java.io.FileWriter; import java.io.IOException; public class AlipayConfig { // 应用ID,您的APPID,收款账号既是您的APPID对应支付宝账号 public static String app_id = ""; // 商户私钥,您的PKCS8格式RSA2私钥 public static String merchant_private_key = ""; // 支付宝公钥,查看地址:https://openhome.alipay.com/platform/keyManage.htm 对应APPID下的支付宝公钥。 public static String alipay_public_key = ""; // 服务器异步通知页面路径 需http://格式的完整路径,不能加?id=123这类自定义参数,必须外网可以正常访问 public static String notify_url = "http://localhost:xxxx/alipay.trade.page.pay-JAVA-UTF-8/notify_url.jsp"; // 页面跳转同步通知页面路径 需http://格式的完整路径,不能加?id=123这类自定义参数,必须外网可以正常访问 //扫码成功之后跳到哪个处理器方法 public static String return_url = "http://localhost:xxxx/xx/xx.do"; // 签名方式 public static String sign_type = "RSA2"; // 字符编码格式 public static String charset = "utf-8"; // 支付宝网关 public static String gatewayUrl ="https://openapi.alipaydev.com/gateway.do"; // 支付宝网关 public static String log_path = "C:\\"; //↑↑↑↑↑↑↑↑↑↑请在这里配置您的基本信息↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑ /** * 写日志,方便测试(看网站需求,也可以改成把记录存入数据库) * @param sWord 要写入日志里的文本内容 */ public static void logResult(String sWord) { FileWriter writer = null; try { writer = new FileWriter(log_path + "alipay_log_" + System.currentTimeMillis()+".txt"); writer.write(sWord); } catch (Exception e) { e.printStackTrace(); } finally { if (writer != null) { try { writer.close(); } catch (IOException e) { e.printStackTrace(); } } } } }
3.提交的.do方法
@RequestMapping("/pay.do") public void pay(String id, String money, String name, HttpServletResponse response) throws Exception { 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 = name; //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(); response.setContentType("text/html;charset=UTF-8"); //输出 response.getWriter().println(result); }
4.支付成功之后,跳转到商城首页
@RequestMapping("/paysuccess.do") 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 out_trade_no = 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"); productService.paysuccess(out_trade_no); 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 "/client/fail.jsp"; //out.println("验签失败"); } }
