1.首先需要有支付宝企业账号
2.账号完成认证
3.下载即时到账接口DEMO
http://aopsdkdownload.cn-hangzhou.alipay-pub.aliyun-inc.com/demo/alipaydirect.zip?spm=a219a.7629140.0.0.jBjnRi&file=alipaydirect.zip
4.打开支付宝配置文件AlipayConfig.java
package com.alipay.config;修改里面的信息。
/* *
*类名：AlipayConfig
*功能：基础配置类
*详细：设置帐户有关信息及返回路径
*版本：3.4
*修改日期：2016-03-08
*说明：
*以下代码只是为了方便商户测试而提供的样例代码，商户可以根据自己网站的需要，按照技术文档编写,并非一定要使用该代码。
*该代码仅供学习和研究支付宝接口使用，只是提供一个参考。

9.异步回调接口
<%这样就OK 了。RES签名必须使用支付宝提供的工具生成并上传公私到支付宝里面。

功能：支付宝服务器异步通知页面
版本：3.3
日期：2012-08-17
说明：
以下代码只是为了方便商户测试而提供的样例代码，商户可以根据自己网站的需要，按照技术文档编写,并非一定要使用该代码。
该代码仅供学习和研究支付宝接口使用，只是提供一个参考。
//***********页面功能说明***********
创建该页面文件时，请留心该页面文件中无任何HTML代码及空格。
该页面不能在本机电脑测试，请到服务器上做测试。请确保外部可以访问该页面。
该页面调试工具请使用写文本函数logResult，该函数在com.alipay.util文件夹的AlipayNotify.java类文件中
如果没有收到该页面返回的 success 信息，支付宝会在24小时内按一定的时间策略重发通知
