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("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);
}
}
</div>
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">

<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">

</form>

</div>
3.网站获得第三方支付的信息
package com.learning.web.servlet;
import java.io.IOException;

import javax.servlet.http.HttpServletRequest;

import com.learning.service.OrderService;
import com.learning.utils.PaymentUtil;
/**
* 该Servlet会在支付成功后 进行调用----- 支付公司 、客户
*
* @author seawind

*/
public class CallbackServlet extends HttpServlet {

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hamc
boolean 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")) {
// 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！");
}
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

}
}
