本文實例為大家分享了java網上商城支付模塊的具體代碼，供大家參考，具體內容如下

1.支付準備

public String paymentPre(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { req.setAttribute("order", orderService.load(req.getParameter("oid"))); return "f:/jsps/order/pay.jsp";}

2.支付方法

public String payment(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { Properties props = new Properties(); props.load(this.getClass().getClassLoader().getResourceAsStream("payment.properties")); /* * 1. 準備13個參數*/ String p0_Cmd = "Buy";//業務類型，固定值Buy String p1_MerId = props.getProperty("p1_MerId");//商號編碼，在易寶的唯一標識String p2_Order = req.getParameter("oid");//訂單編碼String p3_Amt = "0.01";//支付金額String p4_Cur = "CNY";//交易幣種，固定值CNY String p5_Pid = "";//商品名稱String p6_Pcat = "";//商品種類String p7_Pdesc = "";//商品描述String p8_Url = props.getProperty("p8_Url");//在支付成功後，易寶會訪問這個地址。 String p9_SAF = "";//送貨地址String pa_MP = "";//擴展信息String pd_FrpId = req.getParameter("yh");//支付通道String pr_NeedResponse = "1";//應答機制，固定值1 /* * 2. 計算hmac * 需要13個參數* 需要keyValue * 需要加密算法*/ String keyValue = props.getProperty("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); /* * 3. 重定向到易寶的支付網關*/ StringBuilder sb = new StringBuilder("https://www.yeepay.com/app-merchant-proxy/node"); sb.append("?").append("p0_Cmd=").append(p0_Cmd); sb.append("&").append("p1_MerId=").append(p1_MerId); sb.append("&").append("p2_Order=").append(p2_Order); sb.append("&").append("p3_Amt=").append(p3_Amt); sb.append("&").append("p4_Cur=").append(p4_Cur); sb.append("&").append("p5_Pid=").append(p5_Pid); sb.append("&").append("p6_Pcat=").append(p6_Pcat); sb.append("&").append("p7_Pdesc=").append(p7_Pdesc); sb.append("&").append("p8_Url=").append(p8_Url); sb.append("&").append("p9_SAF=").append(p9_SAF); sb.append("&").append("pa_MP=").append(pa_MP); sb.append("&").append("pd_FrpId=").append(pd_FrpId); sb.append("&").append("pr_NeedResponse=").append(pr_NeedResponse); sb.append("&").append("hmac=").append(hmac); resp.sendRedirect(sb.toString()); return null;}

3.回饋方法

當支付成功時，易寶會訪問這裡用兩種方法訪問：
1. 引導用戶的瀏覽器重定向(如果用戶關閉了瀏覽器，就不能訪問這裡了)
2. 易寶的服務器會使用點對點通訊的方法訪問這個方法。（必須回饋success，不然易寶服務器會一直調用這個方法）

 public String back(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { /* * 1. 獲取12個參數*/ String p1_MerId = req.getParameter("p1_MerId"); String r0_Cmd = req.getParameter("r0_Cmd"); String r1_Code = req.getParameter("r1_Code"); String r2_TrxId = req.getParameter("r2_TrxId"); String r3_Amt = req.getParameter("r3_Amt"); String r4_Cur = req.getParameter("r4_Cur"); String r5_Pid = req.getParameter("r5_Pid"); String r6_Order = req.getParameter("r6_Order"); String r7_Uid = req.getParameter("r7_Uid"); String r8_MP = req.getParameter("r8_MP"); String r9_BType = req.getParameter("r9_BType"); String hmac = req.getParameter("hmac"); /* * 2. 獲取keyValue */ Properties props = new Properties(); props.load(this.getClass().getClassLoader().getResourceAsStream("payment.properties")); String keyValue = props.getProperty("keyValue"); /* * 3. 調用PaymentUtil的校驗方法來校驗調用者的身份* >如果校驗失敗：保存錯誤信息，轉發到msg.jsp * >如果校驗通過： * * 判斷訪問的方法是重定向還是點對點，如果要是重定向* 修改訂單狀態，保存成功信息，轉發到msg.jsp * * 如果是點對點：修改訂單狀態，返回success */ boolean bool = 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(!bool) { req.setAttribute("code", "error"); req.setAttribute("msg", "無效的簽名，支付失敗！ （你不是好人）"); return "f:/jsps/msg.jsp"; } if(r1_Code.equals("1")) { orderService.updateStatus(r6_Order, 2); if(r9_BType.equals("1")) { req.setAttribute("code", "success"); req.setAttribute("msg", "恭喜，支付成功！"); return "f:/jsps/msg.jsp"; } else if(r9_BType.equals("2")) { resp.getWriter().print("success"); } } return null;}
