この記事では、参照用のJavaオンラインモール支払いモジュールの特定のコードを共有しています。特定のコンテンツは次のとおりです
1。支払いの準備
public String PayunePre（httpservletrequest req、httpservletresponse resp）throws servletexception、ioexception {req.setattribute（ "order"、ordervice.load（req.getparameter（ "oid"）））; return "f：/jsps/order/pay.jsp";}2。支払い方法

支払いが成功すると、Yibaoは次の2つの方法でアクセスします。
1.ユーザーのブラウザをガイドしてリダイレクトします（ユーザーがブラウザを閉じた場合、彼はこれにアクセスできません）
2。Yibaoのサーバーは、ポイントツーポイント通信を使用してこの方法にアクセスします。 （成功に還元する必要があります。そうしないと、Yibaoサーバーはこの方法を呼び出し続けます）
