在线支付的步骤：

1.index.jsp：是个表单界面，有你要支付的订单号和支付金额，并叫你选择银行开始支付行为。点击“确认支付”后跳转至PaymentRequest

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body><form action="PaymentRequest" method="post" name="paymentform">订单号：<INPUT TYPE="text" NAME="orderid"> 应付金额：￥<INPUT TYPE="text" NAME="amount" size="6">元 <br>请您选择在线支付银行 <br><input TYPE="radio" NAME="pd_FrpId" value="CMBCHINA-NET">招商银行 <br><input TYPE="radio" NAME="pd_FrpId" value="ICBC-NET">工商银行 <br><input TYPE="radio" NAME="pd_FrpId" value="ABC-NET">农业银行 <br><input TYPE="radio" NAME="pd_FrpId" value="CCB-NET">建设银行 <br><input type="submit" value=" 确认支付 " /></form></body></html>

2.PaymentRequestl：从index.jsp表单界面获取数据，再将其设置为request的属性，最后跳转至connection.jsp页面。

package wang.payment.servlet;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import wang.payment.utils.ConfigInfo;import wang.payment.utils.PaymentUtil;/** * Servlet implementation class PaymentRequest */public class PaymentRequest extends HttpServlet {private static final long serialVersionUID = 1L;           /**     * @see HttpServlet#HttpServlet()     */    public PaymentRequest() {        super();        // TODO Auto-generated constructor stub    }/** * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response) */protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {// TODO Auto-generated method stub}/** * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response) */protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {String orderid = request.getParameter("orderid");//订单号String amount = request.getParameter("amount");//支付金额String pd_FrpId = request.getParameter("pd_FrpId");//选择的支付银行String p1_MerId = ConfigInfo.getValue("p1_MerId");String keyValue = ConfigInfo.getValue("keyValue");String merchantCallbackURL = ConfigInfo.getValue("merchantCallbackURL");String messageType = "Buy"; // 请求命令,在线支付固定为BuyString currency = "CNY"; // 货币单位String productDesc = ""; // 商品描述String productCat = ""; // 商品种类String productId = ""; // 商品IDString addressFlag = "0"; // 需要填写送货信息 0：不需要 1:需要String sMctProperties = ""; // 商家扩展信息String pr_NeedResponse = "0"; // 应答机制String md5hmac = PaymentUtil.buildHmac(messageType, p1_MerId, orderid, amount, currency,productId, productCat, productDesc, merchantCallbackURL, addressFlag, sMctProperties, pd_FrpId, pr_NeedResponse, keyValue);request.setAttribute("messageType", messageType);request.setAttribute("merchantID", p1_MerId);request.setAttribute("orderId", orderid);request.setAttribute("amount", amount);request.setAttribute("currency", currency);request.setAttribute("productId", productId);request.setAttribute("productCat", productCat);request.setAttribute("productDesc", productDesc);request.setAttribute("merchantCallbackURL", merchantCallbackURL);request.setAttribute("addressFlag", addressFlag);request.setAttribute("sMctProperties", sMctProperties);request.setAttribute("frpId", pd_FrpId);request.setAttribute("pr_NeedResponse", pr_NeedResponse);request.setAttribute("hmac", md5hmac);request.getRequestDispatcher("connection.jsp").forward(request, response);}}

3.connection.jsp：向银行发起支付请求。从request属性通过EL表达式获取数据，然后通过隐藏表单发给易宝网。

<%@ page language="java" pageEncoding="GBK"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>    <title>发起支付请求</title>    <meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0">      </head>    <body onload="javascript:document.forms[0].submit()">  <!-- http://tech.yeepay.com:8080/robot/debug.action --><form name="yeepay" action="https://www.yeepay.com/app-merchant-proxy/node" method='post'><input type='hidden' name='p0_Cmd'   value="${messageType}"> <!-- 请求命令,在线支付固定为Buy --><input type='hidden' name='p1_MerId' value="${merchantID}"> <!-- 商家ID --><input type="hidden" name="p2_Order" value="${orderId}"> <!-- 商家的交易定单号 --><input type='hidden' name='p3_Amt'   value="${amount}"> <!-- 订单金额 --><input type='hidden' name='p4_Cur'   value="${currency}"> <!-- 货币单位 --><input type='hidden' name='p5_Pid'   value="${productId}"> <!-- 商品ID --><input type='hidden' name='p6_Pcat'  value="${productCat}"> <!-- 商品种类 --><input type='hidden' name='p7_Pdesc' value="${productDesc}"> <!-- 商品描述 --><input type='hidden' name='p8_Url'   value="${merchantCallbackURL}"> <!-- 交易结果通知地址 --><input type='hidden' name='p9_SAF'   value="${addressFlag}"> <!-- 需要填写送货信息 0：不需要 1:需要 --><input type='hidden' name='pa_MP'    value="${sMctProperties}"> <!-- 商家扩展信息 --><input type='hidden' name='pd_FrpId' value="${frpId}"> <!-- 银行ID --><!-- 应答机制 为“1”: 需要应答机制;为“0”: 不需要应答机制 --><input type="hidden" name="pr_NeedResponse"  value="0"><input type='hidden' name='hmac' value="${hmac}"><!-- MD5-hmac验证码 --></form>  </body></html>

4.银行完成支付之后，会给用户返回一些订单处理信息。这时我们要获取这些信息，并判断支付是否成功，若成功，则显示成功页面。

package cn.itcast.servlet;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import cn.itcast.utils.ConfigInfo;import cn.itcast.utils.PanymentUtil;/** * 响应银行支付结果请求 * @author 传智播客 * */public class PaymentResutlResponse extends HttpServlet {public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {this.doPost(request, response);}public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {request.setCharacterEncoding("GBK");String merchantID = ConfigInfo.getValue("p1_MerId"); // 商家IDString keyValue = ConfigInfo.getValue("keyValue"); // 商家密钥String sCmd = request.getParameter("r0_Cmd"); //业务类型String sResultCode = request.getParameter("r1_Code"); //扣款结果,该字段值为1时表示扣款成功.String sTrxId = request.getParameter("r2_TrxId"); //YeePay易宝交易订单号String amount = request.getParameter("r3_Amt");//扣款金额,交易结束后,YeePay易宝交易系统将实际扣款金额返回给商户String currency = request.getParameter("r4_Cur");//交易币种,人民币为CNYString productId = request.getParameter("r5_Pid");//商品IDString orderId = request.getParameter("r6_Order");//商户订单号String userId = request.getParameter("r7_Uid");//YeePay易宝会员IDString mp  = request.getParameter("r8_MP");//商户扩展信息,可以任意填写1K 的字符串,交易返回时将原样返回String bType = request.getParameter("r9_BType");//交易结果通知类型,1: 交易成功回调(浏览器重定向)2: 交易成功主动通知(服务器点对点通讯)String rb_BankId  = request.getParameter("rb_BankId");//支付银行String rp_PayDate = request.getParameter("rp_PayDate");//在银行支付时的时间String hmac = request.getParameter("hmac");//MD5交易签名boolean result = PanymentUtil.verifyCallback(hmac, merchantID, sCmd, sResultCode, sTrxId, amount,currency, productId, orderId, userId, mp, bType, keyValue);if(result){if("1".equals(sResultCode)){//你们这个地方应该把数据库中订单的支付状态设置成已经支付.String message = "订单号为:"+ orderId+ "的订单支付成功了";message += ",用户支付了"+ amount +"元";message +=",交易结果通知类型:";if("1".equals(bType)){ message += "浏览器重定向";}else if("2".equals(bType)){ message += "易宝支付网关后台程序通知";}message += ",易宝订单系统中的订单号为:"+ sTrxId;request.setAttribute("message", message);}else{request.setAttribute("message", "用户支付失败");}}else{request.setAttribute("message", "数据来源不合法");}request.getRequestDispatcher("/WEB-INF/page/paymentResult.jsp").forward(request, response);}}

注：省略了对数据加密的类和读取配置文件的类（ConfigInfo）。
