SSH开发银联在线支付

1.首先导入jar

     netpayclient.jar

2.导入需要的公钥和商户私钥

3.application.properties配置

CHINAPAY_MERCHANT_NO=xxxxxxxxxx      #商户号
PUBLIC_KEY_PATH=/chinapay/PgPubk_new.key   #公钥路径
MERCHANT_KEY_PATH=/chinapay/MerPrK_808080301002146.key    #私钥路径
CHINAPAY_Version=20141120       #版本号
CHINAPAY_OrderHead=000002146    #订单头
CHINAPAY_CuryId=156       #交易币种
CHINAPAY_TransType=0001   #交易类型（付款）
CHINAPAY_BgRetUrl=https://www.hhr360.com/user_recharge/bgRet.htm         #回调后台地址
CHINAPAY_PageRetUrl=https://www.hhr360.com/user_recharge/pageRet.htm     #回调前台地址
CHINAPAY_GateId=         #支付网关号，可选
CHINAPAY_Priv1=hhr360    #商户私有域，可选
CHINAPAY_QueryUrl=http://console.chinapay.com/QueryWeb/processQuery.jsp  #查询地址

4.支付action

    /**
	 * 银联充值申请成功
	 * 
	 * @return
	 * @throws Exception
	 */
	@Action("quickSucced")
	public String quickSucced() {
		try {
			FuRecharge recharge = fuRechargeService.get(id);
			if (recharge != null) {
				chinapay.PrivateKey key1 = new chinapay.PrivateKey();
				chinapay.SecureLink t;
				// 注意要用哪一个商户号签名就要用对应的key文件
				key1.buildKey(Property.getProperty("CHINAPAY_MERCHANT_NO"), 0, this.getServletContext().getRealPath(Property.getProperty("MERCHANT_KEY_PATH"))); 
				t = new chinapay.SecureLink(key1);
				SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
				NumberFormat ndf1 = new DecimalFormat("0000000");
				NumberFormat ndf2 = new DecimalFormat("000000000000");
				// 支付订单数据准备
				String MerId = Property.getProperty("CHINAPAY_MERCHANT_NO");
				String OrdId = Property.getProperty("CHINAPAY_OrderHead") + ndf1.format(recharge.getId());// 000002146+0000074
				String TransDate = sdf.format(new Date());
				String Version = Property.getProperty("CHINAPAY_Version");
				String TransAmt = ndf2.format(recharge.getRechargeMoney().multiply(new BigDecimal(100)));
				String CuryId = Property.getProperty("CHINAPAY_CuryId");
				String TransType = Property.getProperty("CHINAPAY_TransType");
				String BgRetUrl = Property.getProperty("CHINAPAY_BgRetUrl");
				String PageRetUrl = Property.getProperty("CHINAPAY_PageRetUrl");
				String GateId = Property.getProperty("CHINAPAY_GateId");
				String Priv1 = Property.getProperty("CHINAPAY_Priv1");
				String ChkValue = t.Sign(MerId + OrdId + TransAmt + CuryId + TransDate + TransType + Version + BgRetUrl + PageRetUrl + GateId + Priv1);
				
				JSONObject obj = new JSONObject();
				obj.put("MerId", MerId);
				obj.put("OrdId", OrdId);
				obj.put("TransAmt", TransAmt);
				obj.put("CuryId", CuryId);
				obj.put("TransDate", TransDate);
				obj.put("TransType", TransType);
				obj.put("Version", Version);
				obj.put("BgRetUrl", BgRetUrl);
				obj.put("PageRetUrl", PageRetUrl);
				obj.put("GateId", GateId);
				obj.put("Priv1", Priv1);
				obj.put("ChkValue", ChkValue);
				this.getActionContext().put("obj", obj);
			}
			this.getActionContext().put("poundageMoney", poundageMoney);//上一个页面传过来的参数：手续费
		} catch (Exception e) {
			e.printStackTrace();
		}
		return SUCCESS;
	}

5.提交表单给银联

<div id="one_1" class="display-b">
         <form action="https://payment.chinapay.com/pay/TransGet" target="_blank" id="chinaForm" METHOD=POST>
			<input type=hidden name="MerId" id="MerId" value="${obj.MerId }">

     </div>

6.回调action，根据支付返回的状态码做相关业务处理
