public static String RSA_PRIVATE_KEY = "";
// 服务器异步通知页面路径 需http://或者https://格式的完整路径,不能加?id=123这类自定义参数,必须外网可以正常访问
public static String notify_url = "http://商家端口号/alipay.trade.wap.pay-JAVA-UTF-8/notify_url.jsp";
// 页面跳转同步通知页面路径 需http://或者https://格式的完整路径,不能加?id=123这类自定义参数,必须外网可以正常访问 商户可以自定义同步跳转地址
public static String return_url = "http://商家端口号/alipay.trade.wap.pay-JAVA-UTF-8/return_url.jsp";
