2.付款方式
public String payment(HttpServletRequest req, HttpServletResponse resp)

/*

String p4_Cur = "CNY";//交易幣種，固定值CNY
String p5_Pid = "";//商品名稱
String p6_Pcat = "";//商品種類
String p7_Pdesc = "";//商品描述
String p8_Url = props.getProperty("p8_Url");//在支付成功后，易寶會(huì)訪問這個(gè)地址。
String p9_SAF = "";//送貨地址

3.回饋方法
當(dāng)付款成功時(shí)，易寶會(huì)訪問這裡
用兩種方法訪問：
1. 引導(dǎo)用戶的瀏覽器重定向(如果用戶關(guān)閉了瀏覽器，就不能訪問這裡了)
2. 易寶的伺服器會(huì)使用點(diǎn)對(duì)點(diǎn)通訊的方法來存取這個(gè)方法。 （必須回饋success，不然易寶伺服器會(huì)一直呼叫這個(gè)方法）
