2024-02-26 01:14:03 56

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

packagecom.learning.web.servlet;

importjava.io.IOException;
importjava.util.ResourceBundle;

importjavax.servlet.ServletException;
importjavax.servlet.annotation.WebServlet;
importjavax.servlet.http.HttpServlet;
importjavax.servlet.http.HttpServletRequest;
importjavax.servlet.http.HttpServletResponse;

importcom.learning.utils.PaymentUtil;

@WebServlet("/payOnline")
publicclassPayOnlineextendsHttpServlet{
privatestaticfinallongserialVersionUID=1L;

protectedvoiddoGet(HttpServletRequestrequest,HttpServletResponseresponse)throwsServletException,IOException{
doPost(request,response);
}


protectedvoiddoPost(HttpServletRequestrequest,HttpServletResponseresponse)throwsServletException,IOException{

Stringorderid=request.getParameter("orderid");
Stringmoney=request.getParameter("money");

//银行
Stringpd_FrpId=request.getParameter("pd_FrpId");

//发给支付公司需要哪些数据
Stringp0_Cmd="Buy";
Stringp1_MerId=ResourceBundle.getBundle("/WEB-INF/classes/merchantInfo").getString(
"p1_MerId");
Stringp2_Order=orderid;
Stringp3_Amt=money;
Stringp4_Cur="CNY";
Stringp5_Pid="";
Stringp6_Pcat="";
Stringp7_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)
Stringp8_Url="http://115.170.37.189/day19pay/callback";
Stringp9_SAF="";
Stringpa_MP="";
Stringpr_NeedResponse="1";
//加密hmac需要密钥
StringkeyValue=ResourceBundle.getBundle("merchantInfo").getString(
"keyValue");
Stringhmac=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）

<%@pagelanguage="java"contentType="text/html;charset=UTF-8"
pageEncoding="UTF-8"%>

<%@taglibprefix="p"uri="http://www.itcast.cn/tag"%>




Inserttitlehere





订单号：${p2_Order},付款金额：${p3_Amt}

3.网站获得第三方支付的信息

importjavax.servlet.ServletException;
importjavax.servlet.http.HttpServlet;
importjavax.servlet.http.HttpServletRequest;

importcom.learning.utils.PaymentUtil;


/**

publicclassCallbackServletextendsHttpServlet{

publicvoiddoGet(HttpServletRequestrequest,HttpServletResponseresponse)
throwsServletException,IOException{
//获得回调所有数据
Stringp1_MerId=request.getParameter("p1_MerId");
Stringr0_Cmd=request.getParameter("r0_Cmd");
Stringr1_Code=request.getParameter("r1_Code");
Stringr2_TrxId=request.getParameter("r2_TrxId");
Stringr3_Amt=request.getParameter("r3_Amt");
Stringr4_Cur=request.getParameter("r4_Cur");

Stringr8_MP=request.getParameter("r8_MP");
Stringr9_BType=request.getParameter("r9_BType");
Stringrb_BankId=request.getParameter("rb_BankId");
Stringro_BankOrderId=request.getParameter("ro_BankOrderId");
Stringrp_PayDate=request.getParameter("rp_PayDate");
Stringrq_CardNo=request.getParameter("rq_CardNo");
Stringru_Trxtime=request.getParameter("ru_Trxtime");
//身份校验---判断是不是支付公司通知你
Stringhmac=request.getParameter("hmac");
StringkeyValue=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
booleanisValid=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("付款成功！等待商城进一步操作！等待收货...");
}elseif(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
OrderServiceorderService=newOrderService();
orderService.modifyOrderState(p1_MerId);

//回复支付公司
response.getWriter().print("success");
}
}else{
//数据无效
System.out.println("数据被篡改！");
}
}

publicvoiddoPost(HttpServletRequestrequest,HttpServletResponseresponse)
throwsServletException,IOException{
doGet(request,response);
}

}
