吐槽一下：

支付宝的接口和微信的DEMO和文档真心太难看懂了，乱七八糟，都不知道去哪里找自己要的东西，最近几天我们公司需要做类似的开发，我作为先锋，率先解决java集成支付宝支付和微信支付接口工作。

我们的工作环境：JSP网站+支付接口，目前工作的支付宝接口为20160912，微信为V3版本，如遇到版本升级，请联系相关机构的客户服务人员升级。

本文介绍JSP+支付宝接口，本文非原创。

新手注意：

1、本文使用的接口地址和参数为沙箱的地址，无论你在使用沙箱或者正式地址，务必核实使用接口地址和参数，不要想当然。

2、本文使用JAR包：

alipay-sdk-java20160912220103.jar
commons-codec-1.6.jar
commons-httpclient-3.0.1.jar
commons-logging-1.1.1.jar
fastjson-1.2.7.jar
json-lib-2.2.3-jdk13.jar
json.jar
jsp-api.jar
servlet-api.jar

说明：

alipay-sdk-java 是官方支付SDK，请到官方下载，本文使用版本20160912

首页调用：
