我们必须按照以下步骤在 Java Web 应用程序中配置 Paypal。这里我展示了 Paypal 到 Paypal 和 CreditCard 到 Paypal 付款的配置。
1.create one sandbox account.
2.create web application.
3.Integrate the following struts2 action with your code.If you want to use with any other then just take methods and use directly.
1.创建一个沙箱帐户。
2.创建网络应用程序。
3.将下面的struts2动作与你的代码集成。如果你想与其他任何一起使用，那么只需取方法并直接使用。

This is working fine for me.Hope it will help to those who want to configure payment through paypal.
这对我来说很好用。希望对那些想通过贝宝配置付款的人有所帮助。
