本文实例为大家分享了javaweb在线支付功能的具体实现代码，供大家参考，具体内容如下

package com.learning.web.servlet;import java.io.IOException;import java.util.ResourceBundle;import javax.servlet.ServletException;import javax.servlet.annotation.WebServlet;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import com.learning.utils.PaymentUtil;@WebServlet("/payOnline")public class PayOnline extends HttpServlet {  private static final long serialVersionUID = 1L;      protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {      doPost(request, response);  }  protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {      String orderid = request.getParameter("orderid");    String money = request.getParameter("money");            // 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("/WEB-INF/classes/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(本项目网址)        String p8_Url = "http://115.170.37.189/day19pay/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);        // 生成url --- url?        request.setAttribute("pd_FrpId", pd_FrpId);        request.setAttribute("p0_Cmd", p0_Cmd);        request.setAttribute("p1_MerId", p1_MerId);        request.setAttribute("p2_Order", p2_Order);        request.setAttribute("p3_Amt", p3_Amt);        request.setAttribute("p4_Cur", p4_Cur);        request.setAttribute("p5_Pid", p5_Pid);        request.setAttribute("p6_Pcat", p6_Pcat);        request.setAttribute("p7_Pdesc", p7_Pdesc);        request.setAttribute("p8_Url", p8_Url);        request.setAttribute("p9_SAF", p9_SAF);        request.setAttribute("pa_MP", pa_MP);        request.setAttribute("pr_NeedResponse", pr_NeedResponse);        request.setAttribute("hmac", hmac);        request.getRequestDispatcher("/confirm.jsp").forward(request, response);          }}

2.用户确认提交的信息（confirm.jsp）

<%@ page language="java" contentType="text/html; charset=UTF-8"  pageEncoding="UTF-8"%><%@taglib prefix="p" uri="http://www.itcast.cn/tag"%><!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>  <p:user />  <!-- 确认支付form -->  <form action="https://www.yeepay.com/app-merchant-proxy/node"    method="get">    <h3>订单号：${p2_Order},付款金额 ：${p3_Amt }</h3>    <input type="hidden" name="pd_FrpId" value="${pd_FrpId }" /> <input      type="hidden" name="p0_Cmd" value="${p0_Cmd }" /> <input      type="hidden" name="p1_MerId" value="${p1_MerId }" /> <input      type="hidden" name="p2_Order" value="${p2_Order }" /> <input      type="hidden" name="p3_Amt" value="${p3_Amt }" /> <input      type="hidden" name="p4_Cur" value="${p4_Cur }" /> <input      type="hidden" name="p5_Pid" value="${p5_Pid }" /> <input      type="hidden" name="p6_Pcat" value="${p6_Pcat }" /> <input      type="hidden" name="p7_Pdesc" value="${p7_Pdesc }" /> <input      type="hidden" name="p8_Url" value="${p8_Url }" /> <input      type="hidden" name="p9_SAF" value="${p9_SAF }" /> <input      type="hidden" name="pa_MP" value="${pa_MP }" /> <input type="hidden"      name="pr_NeedResponse" value="${pr_NeedResponse }" /> <input      type="hidden" name="hmac" value="${hmac }" /> <input type="submit"      value="确认支付" />  </form></body></html>

3.网站获得第三方支付的信息
