实例介绍

【实例简介】

java版和php版都是经本人测试成功后上传，功能都没有问题。代码逻辑有困惑时可以参考开发文档，上面很清楚。

java版说明

1. 在开通微信支付的公众号下访问 htpp://服务器地址/mainServlet

2. 修改MainServlet.java和TopayServlet.java 里面的商户参数，授权返回地址和notify_url部分即可。

3. 代码是别人的劳动成果，经自己稍微修改后测试成功，demo并没有十分的简化，大家可以做一个参考吧。如果出现签名失败，仔细检查下自己填写的appid和partnerkey是否正确。

4. 请注意：微信支付成功后的通知的url为notifyServlet,sb是返回的xml

5.最后祝大家都通过微信支付的测试。
