javaEE MVC模式 提交订单和支付功能

这次使用的是易宝支付接口。

1.确认订单功能的实现。

1）OrderDao类

//更新订单public void updateOrder(Orders order) throws SQLException{QueryRunner runner=new QueryRunner(DataSourceUtils.getDataSource());String sql="update orders set address=?,name=?,telephone=? where oid=?";runner.update(sql, order.getAddress(),order.getName(),order.getTelephone(),order.getOid());}

2）OrderService类

//更新订单public void updateOrder(Orders order){try {orderDao.updateOrder(order);} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();}}

3）OrderServlet类

public void confirmSubmitOrder(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException{  Map<String,String[]> properties=  request.getParameterMap();  Orders order=new Orders();  try {BeanUtils.populate(order, properties);} catch (IllegalAccessException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (InvocationTargetException e) {// TODO Auto-generated catch blocke.printStackTrace();}orderService.updateOrder(order);

}

4）前台页面就不写出来了。

2.使用易宝支付

1）导入merchantInfo.properties 放在src目录下

p1_MerId=10015111600keyValue=69cl522AV6q613Ii4W6u8K6XuW8vM1N6bFgyv769220IuYe9u37N4y7rI4Plcallback=http://localhost:8080/ShopStore/callback

2）导入PaymentUtil.java工具类

package com.yinhe.utils;import java.io.UnsupportedEncodingException;import java.security.MessageDigest;import java.security.NoSuchAlgorithmException;import java.util.Arrays;public class PaymentUtil {private static String encodingCharset = "UTF-8";/** * 生成hmac方法 *  * @param p0_Cmd 业务类型 * @param p1_MerId 商户编号 * @param p2_Order 商户订单号 * @param p3_Amt 支付金额 * @param p4_Cur 交易币种 * @param p5_Pid 商品名称 * @param p6_Pcat 商品种类 * @param p7_Pdesc 商品描述 * @param p8_Url 商户接收支付成功数据的地址 * @param p9_SAF 送货地址 * @param pa_MP 商户扩展信息 * @param pd_FrpId 银行编码 * @param pr_NeedResponse 应答机制 * @param keyValue 商户密钥 * @return */public static String buildHmac(String p0_Cmd,String p1_MerId,String p2_Order, String p3_Amt, String p4_Cur,String p5_Pid, String p6_Pcat,String p7_Pdesc,String p8_Url, String p9_SAF,String pa_MP,String pd_FrpId,String pr_NeedResponse,String keyValue) {StringBuilder sValue = new StringBuilder();// 业务类型sValue.append(p0_Cmd);// 商户编号sValue.append(p1_MerId);// 商户订单号sValue.append(p2_Order);// 支付金额sValue.append(p3_Amt);// 交易币种sValue.append(p4_Cur);// 商品名称sValue.append(p5_Pid);// 商品种类sValue.append(p6_Pcat);// 商品描述sValue.append(p7_Pdesc);// 商户接收支付成功数据的地址sValue.append(p8_Url);// 送货地址sValue.append(p9_SAF);// 商户扩展信息sValue.append(pa_MP);// 银行编码sValue.append(pd_FrpId);// 应答机制sValue.append(pr_NeedResponse);return PaymentUtil.hmacSign(sValue.toString(), keyValue);}/** * 返回校验hmac方法 *  * @param hmac 支付网关发来的加密验证码 * @param p1_MerId 商户编号 * @param r0_Cmd 业务类型 * @param r1_Code 支付结果 * @param r2_TrxId 易宝支付交易流水号 * @param r3_Amt 支付金额 * @param r4_Cur 交易币种 * @param r5_Pid 商品名称 * @param r6_Order 商户订单号 * @param r7_Uid 易宝支付会员ID * @param r8_MP 商户扩展信息 * @param r9_BType 交易结果返回类型 * @param keyValue 密钥 * @return */public static boolean verifyCallback(String hmac, String p1_MerId,String r0_Cmd, String r1_Code, String r2_TrxId, String r3_Amt,String r4_Cur, String r5_Pid, String r6_Order, String r7_Uid,String r8_MP, String r9_BType, String keyValue) {StringBuilder sValue = new StringBuilder();// 商户编号sValue.append(p1_MerId);// 业务类型sValue.append(r0_Cmd);// 支付结果sValue.append(r1_Code);// 易宝支付交易流水号sValue.append(r2_TrxId);// 支付金额sValue.append(r3_Amt);// 交易币种sValue.append(r4_Cur);// 商品名称sValue.append(r5_Pid);// 商户订单号sValue.append(r6_Order);// 易宝支付会员IDsValue.append(r7_Uid);// 商户扩展信息sValue.append(r8_MP);// 交易结果返回类型sValue.append(r9_BType);String sNewString = PaymentUtil.hmacSign(sValue.toString(), keyValue);return sNewString.equals(hmac);}/** * @param aValue * @param aKey * @return */public static String hmacSign(String aValue, String aKey) {byte k_ipad[] = new byte[64];byte k_opad[] = new byte[64];byte keyb[];byte value[];try {keyb = aKey.getBytes(encodingCharset);value = aValue.getBytes(encodingCharset);} catch (UnsupportedEncodingException e) {keyb = aKey.getBytes();value = aValue.getBytes();}Arrays.fill(k_ipad, keyb.length, 64, (byte) 54);Arrays.fill(k_opad, keyb.length, 64, (byte) 92);for (int i = 0; i < keyb.length; i++) {k_ipad[i] = (byte) (keyb[i] ^ 0x36);k_opad[i] = (byte) (keyb[i] ^ 0x5c);}MessageDigest md = null;try {md = MessageDigest.getInstance("MD5");} catch (NoSuchAlgorithmException e) {return null;}md.update(k_ipad);md.update(value);byte dg[] = md.digest();md.reset();md.update(k_opad);md.update(dg, 0, 16);dg = md.digest();return toHex(dg);}public static String toHex(byte input[]) {if (input == null)return null;StringBuffer output = new StringBuffer(input.length * 2);for (int i = 0; i < input.length; i++) {int current = input[i] & 0xff;if (current < 16)output.append("0");output.append(Integer.toString(current, 16));}return output.toString();}/** *  * @param args * @param key * @return */public static String getHmac(String[] args, String key) {if (args == null || args.length == 0) {return (null);}StringBuffer str = new StringBuffer();for (int i = 0; i < args.length; i++) {str.append(args[i]);}return (hmacSign(str.toString(), key));}/** * @param aValue * @return */public static String digest(String aValue) {aValue = aValue.trim();byte value[];try {value = aValue.getBytes(encodingCharset);} catch (UnsupportedEncodingException e) {value = aValue.getBytes();}MessageDigest md = null;try {md = MessageDigest.getInstance("SHA");} catch (NoSuchAlgorithmException e) {e.printStackTrace();return null;}return toHex(md.digest(value));}//public static void main(String[] args) {//System.out.println(hmacSign("AnnulCard1000043252120080620160450.0http://localhost/SZXpro/callback.asp杩?4564868265473632445648682654736324511","8UPp0KE8sq73zVP370vko7C39403rtK1YwX40Td6irH216036H27Eb12792t"));//}}

3）OrderServlet类

//确认订单public void confirmSubmitOrder(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException{...//上述代码省略//只接入一个接口，这个接口已经集成所有的银行接口了  ，这个接口是第三方支付平台提供的//接入的是易宝支付// 获得 支付必须基本数据String orderid = request.getParameter("oid");//String money = order.getTotal()+"";//支付金额String money = "0.01";//支付金额// 银行String pd_FrpId = request.getParameter("pd_FrpId");// 发给支付公司需要哪些数据String p0_Cmd = "Buy";String p1_MerId = ResourceBundle.getBundle("merchantInfo").getString("p1_MerId");String p2_Order = orderid;String p3_Amt = money;String p4_Cur = "CNY";String p5_Pid = "";String p6_Pcat = "";String p7_Pdesc = "";// 支付成功回调地址 ---- 第三方支付公司会访问、用户访问// 第三方支付可以访问网址String p8_Url = ResourceBundle.getBundle("merchantInfo").getString("callback");String p9_SAF = "";String pa_MP = "";String pr_NeedResponse = "1";// 加密hmac 需要密钥String keyValue = ResourceBundle.getBundle("merchantInfo").getString("keyValue");String hmac = PaymentUtil.buildHmac(p0_Cmd, p1_MerId, p2_Order, p3_Amt,p4_Cur, p5_Pid, p6_Pcat, p7_Pdesc, p8_Url, p9_SAF, pa_MP,pd_FrpId, pr_NeedResponse, keyValue);String url = "https://www.yeepay.com/app-merchant-proxy/node?pd_FrpId="+pd_FrpId+"&p0_Cmd="+p0_Cmd+"&p1_MerId="+p1_MerId+"&p2_Order="+p2_Order+"&p3_Amt="+p3_Amt+"&p4_Cur="+p4_Cur+"&p5_Pid="+p5_Pid+"&p6_Pcat="+p6_Pcat+"&p7_Pdesc="+p7_Pdesc+"&p8_Url="+p8_Url+"&p9_SAF="+p9_SAF+"&pa_MP="+pa_MP+"&pr_NeedResponse="+pr_NeedResponse+"&hmac="+hmac;//重定向到第三方支付平台response.sendRedirect(url);}

3.调用回调方法，处理订单状态

 1）OrderDao类

//更新订单public void updateOrder(Orders order) throws SQLException{QueryRunner runner=new QueryRunner(DataSourceUtils.getDataSource());String sql="update orders set address=?,name=?,telephone=? where oid=?";runner.update(sql, order.getAddress(),order.getName(),order.getTelephone(),order.getOid());}

2）OrderService类

//更新订单public void updateOrder(Orders order){try {orderDao.updateOrder(order);} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();}}

3）回调servlet类

public class CallbackServlet extends BaseServlet {protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {this.doPost(request, response);}protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {// 获得回调所有数据String p1_MerId = request.getParameter("p1_MerId");String r0_Cmd = request.getParameter("r0_Cmd");String r1_Code = request.getParameter("r1_Code");String r2_TrxId = request.getParameter("r2_TrxId");String r3_Amt = request.getParameter("r3_Amt");String r4_Cur = request.getParameter("r4_Cur");String r5_Pid = request.getParameter("r5_Pid");//订单编号String r6_Order = request.getParameter("r6_Order");String r7_Uid = request.getParameter("r7_Uid");String r8_MP = request.getParameter("r8_MP");String r9_BType = request.getParameter("r9_BType");String rb_BankId = request.getParameter("rb_BankId");String ro_BankOrderId = request.getParameter("ro_BankOrderId");String rp_PayDate = request.getParameter("rp_PayDate");String rq_CardNo = request.getParameter("rq_CardNo");String ru_Trxtime = request.getParameter("ru_Trxtime");// 身份校验 --- 判断是不是支付公司通知你String hmac = request.getParameter("hmac");String keyValue = ResourceBundle.getBundle("merchantInfo").getString("keyValue");// 自己对上面数据进行加密 --- 比较支付公司发过来hamcboolean isValid = PaymentUtil.verifyCallback(hmac, p1_MerId, r0_Cmd,r1_Code, r2_TrxId, r3_Amt, r4_Cur, r5_Pid, r6_Order, r7_Uid,r8_MP, r9_BType, keyValue);if (isValid) {// 响应数据有效if (r9_BType.equals("1")) {//修改订单状态OrderService orderService=new OrderService();orderService.updateOrderStateByOid(r6_Order);// 浏览器重定向response.setContentType("text/html;charset=utf-8");response.getWriter().println("<h1>付款成功！等待商城进一步操作！等待收货...</h1>");} else if (r9_BType.equals("2")) {// 服务器点对点 --- 支付公司通知你System.out.println("付款成功！");// 修改订单状态 为已付款// 回复支付公司response.getWriter().print("success");}} else {// 数据无效System.out.println("数据被篡改！");}}}
