下面就拿我项目中的部分代码来实践一下.
支付请求
首先,是提交表单
fund.jsp(这里我表单只需要用户填交易金额,其他的订单号之类的全部后台生成)
<form id="deposit" name= "alipaysubmit" method="post" target="_blank">
<input type="hidden" name="user.id" value= "<shiro:principal property="id"/>" />
<table cellpadding="10">
<tr>
<td>账户余额</td>
<td class="balance" id="userBalance"></td>
</tr>
<tr>
<td><i class="zfb"></i></td>
<td style="padding-bottom: 0px;">亲爱的<span
class="suppliment_user" id="suppliment_user"></span>,您可以使用支付宝充值积善分,请填写以下信息
</td>
</tr>
<tr>
<td></td>
<td><label class="radio inline"> <input type="radio"
name="amount" id="optionsRadios7" value="option7">自定义<input
class="compliment_count" name="amount" placeholder="充值金额">元
</label></td>
</tr>
<tr>
<td></td>
<td class="warm_prompt">温馨提示:<br />1.采用支付宝充值,1元可以充值1积善值。<br />2.若出现已充值成功的提示,但积善值未到账,可能是网络或者系统繁忙导致,我们会在2个工作日内核对后为您充值<br />3在充值过程中如出现网页错误或打开缓慢时,请先查询支付宝的交易记录,检查扣款是否成功;然后查看积善之家账户是否成功充值。若没有确认,请不要反复刷新页面,以防止重复购买。
</td>
</tr>
<tr>
<td></td>
<td><button class="affirm-donate" id="rechange">立即充值</button></td>
</tr>
</table>
</form>
fund.js
$('#rechange').click(function(e) {
//$this = $("#deposit");
e.preventDefault();
var postData = $.toJSON(form2js('deposit', '.', true));
console.log(postData);
$.ajax({
url : $CONFIG.base_url+ "/api/fund_detail/web/deposit",
type : "POST",
data : postData,
contentType : "application/json",
success : function(data) { data.total_fee = data.total_fee/100;//测试成功后请删除
console.log(data);
console.log(data.sHtmlText);
$("#deposit").append(data.sHtmlText);//后台会返回一个新的交易表单,并自动提交。所以随便放一个地方就OK
},
error : function() {
}
});
});
下面就是后台代码:
AlipayController.java(里面的User FundDetail都是我自己定义的实体类,与支付本身没有关系)部分配置在AlipayConfig中,
@RequestMapping(value = "/web/deposit", method = RequestMethod.POST)
public ResponseEntity<HttpEntity> deposit(@RequestBody FundDetail newfundDetail,Model model) {
Date date = new Date();
User user = new User();
FundDetail fundDetail = new FundDetail();
Map<String, String> sParaTemp = new HashMap<String, String>();
// 支付类型
// 必填,不能修改
String payment_type = "1";
// 服务器异步通知页面路径
// 需http://格式的完整路径,不能加?id=123这类自定义参数
String notify_url = "http://jishanjia.lanbaoo.com/api/alipay/async";
// 页面跳转同步通知页面路径
// 需http://格式的完整路径,不能加?id=123这类自定义参数,不能写成http://localhost/
String return_url = "http://jishanjia.lanbaoo.com/alipay/return_url";
// 商户订单号.
// 商户网站订单系统中唯一订单号,必填
//String out_trade_no = date.getTime() + "";
// 订单名称
// 必填
String subject = "充值积善值";
// 防钓鱼时间戳
// 若要使用请调用类文件submit中的query_timestamp函数
String anti_phishing_key = "";
// 客户端的IP地址
// 非局域网的外网IP地址,如:221.0.0.1
String exter_invoke_ip = ""; user = userService.getUser(newfundDetail.getUser().getId());
fundDetail.setUser(user);
fundDetail.setActionType(3);
fundDetail.setTradeNo(date.getTime()+user.getId().toString());
fundDetail.setAmount(newfundDetail.getAmount());
fundDetailService.addFundDetail(fundDetail); Double total_fee = (double) (fundDetail.getAmount()/100d);//测试结束后删除
sParaTemp.put("total_fee", total_fee.toString());
sParaTemp.put("service", "create_direct_pay_by_user");
sParaTemp.put("partner", AlipayConfig.partner);
sParaTemp.put("_input_charset", AlipayConfig.input_charset);
sParaTemp.put("payment_type", payment_type);
sParaTemp.put("notify_url", notify_url);
sParaTemp.put("return_url", return_url);
sParaTemp.put("seller_id", AlipayConfig.seller_id);
sParaTemp.put("out_trade_no", date.getTime()+user.getId().toString());
sParaTemp.put("subject", subject);
sParaTemp.put("anti_phishing_key", anti_phishing_key);
sParaTemp.put("exter_invoke_ip", exter_invoke_ip);
sParaTemp.put("key", AlipayConfig.key); String sHtmlText = AlipaySubmit.buildRequest(sParaTemp,"get","确认"); model.addAttribute("sHtmlText", sHtmlText);
model.addAttribute("fundDetail", fundDetail); return new ResponseEntity(model, HttpStatus.OK);
}
到此一次交易就成功了
异步通知和跳转:
AlipayNotifyController.java(对应上面的notify_url)
@RequestMapping(value = "/async",method = RequestMethod.GET)
@ResponseBody
public String async(HttpServletRequest request){
Map<String,String> params = new HashMap<String,String>();
Map requestParams = request.getParameterMap();
for (Iterator iter = requestParams.keySet().iterator(); iter.hasNext();) {
String name = (String) iter.next();
String[] values = (String[]) requestParams.get(name);
String valueStr = "";
for (int i = 0; i < values.length; i++) {
valueStr = (i == values.length - 1) ? valueStr + values[i]: valueStr + values[i] + ",";
}
//乱码解决,这段代码在出现乱码时使用。如果mysign和sign不相等也可以使用这段代码转化
//valueStr = new String(valueStr.getBytes("ISO-8859-1"), "gbk");
params.put(name, valueStr);
}
String tradeNo = request.getParameter("out_trade_no");
String tradeStatus = request.getParameter("trade_status");
//String notifyId = request.getParameter("notify_id");
if(AlipayNotify.verify(params)){//验证成功
if(tradeStatus.equals("TRADE_FINISHED") || tradeStatus.equals("TRADE_SUCCESS")) {
FundDetail fundDetail = new FundDetail();
fundDetail = fundDetailService.getFundDetail(tradeNo);
fundDetail.setActionType(1);
fundDetailService.updateFundDetail(fundDetail);
User user = new User();
user = userService.getUser(fundDetail.getUser().getId());
user.setFund(user.getFund() + fundDetail.getAmount());
userService.updateUser(user);
System.out.println(">>>>>充值成功" + tradeNo);
}
return "success";
}else{//验证失败
return "fail";
}
}
return_url跟notify_url差不多。在return_url控制交易成功后的跳转页面就可以了.
至此,一次支付宝即时到账交易就完成了
