springMVC中使用支付宝支付,沙箱环境

之前的一篇博客已经介绍过了支付宝的官方Demo,

支付宝沙箱环境测试

把Demo放到springMVC环境下

引入依赖

<dependency>
	<groupId>org.apache.commons</groupId>
	<artifactId>commons-logging</artifactId>
	<version>1.1.1</version>
</dependency>

<dependency>
	<groupId>com.alipay.sdk</groupId>
	<artifactId>alipay-sdk-java</artifactId>
	<version>4.7.1.ALL</version>
</dependency>
<dependency>
	<groupId>com.alibaba</groupId>
	<artifactId>fastjson</artifactId>
	<version>1.2.60</version>
</dependency>
<dependency>
	<groupId>org.bouncycastle</groupId>
	<artifactId>bcprov-jdk15on</artifactId>
	<version>1.63</version>
</dependency>

把Demo中的已经填好数据的AlipayConfig类拿过来放到新建的config包中

index.jsp页面拿过来放到自己指定的springMVC的jsp文件存放路径下

我这里是

随便写一个controller用于跳转到index页面

新建一个controller 名为AlipayDemo

内容如下,支付、交易查询、退款、退款查询、交易关闭都在这里。

每个方法的返回值都是ModelAndView,我这里新建了一个temp.jsp页面,都去这个页面显示数据了。支付宝这几个接口返回的数据result,支付接口返回的result是一个HTML字符串,里面有一个表单一句JS脚本用来提交表单。其他接口的是json串。我直接显示在页面上了。

index页面的表单action路径,由于我这里转发到index页面的路径是user/fun。是user下面的,所以去上层目录找alipay接口

比如支付这里支付这里我写的是../alipay/pay,其他的也是这样写。

temp.jsp 页面只有一句<%=request.getAttribute("result") %>

return_url.jsp 页面

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<%
	String trade_no = (String)request.getAttribute("trade_no");
	String out_trade_no = (String)request.getAttribute("out_trade_no");
	String total_amount = (String)request.getAttribute("total_amount");
	if(trade_no == null && out_trade_no == null && total_amount == null){
%>
		验证失败
<%
	}
	out.println("商户订单号:"+trade_no);
	out.println("支付宝交易号:"+out_trade_no);
	out.println("付款金额:"+total_amount);
%>
</body>
</html>
