Java微信网站支付宝支付接口快速接入
此篇文章写的是微信网站支付宝支付，这篇文章写接入的完整过程和原码，如果需要支付宝完成支付后的异步通知相关的代码，请看下一篇博客。
支付宝API网站：https://docs.open.alipay.com/203/105285/
因为微信限制的原因，所以支付宝不能在微信的页面完成支付 ，所以我们要先将其转发到手机自带浏览器中，然后调用支付宝的接口，如果手机中下载了支付宝客户端，就会提示打开客户端，如果没有客户端就跳到支付宝浏览器登录页面，我实现的原理是用户点击了付款直接提示页。
这个页面时微信提供的页面，我们做了修改，此页面在安卓和苹果显示不同的样式，所以不用修改，此页面原码：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
//获取orderid
String orderid = (String)request.getParameter("orderid");
if(orderid!=null){
request.setAttribute("orderid", orderid);
}
%>

%>这个jsp执行完成后就会，就会输出一个form表单，包括form表单提交的相关js代码，浏览器会自动执行提交，注意此jsp中ReturnUrl是本地成功后转发的jsp，用户可以看到的，可以提示用户已经支付成功。NotifyUrl是用户支付成功后，支付宝会向你的服务器发请求，会把用户支付的参数通知给你，也就是支付宝的异步通知，如果需要这部分代码，请看下一篇文章。
这个jsp出现的页面是这样的。
然后便是支付宝客户端，打开付款。
支付宝异步通知原码，请看下一篇博客。
