配置申請地址 https://open.alipay.com/platform/home.html(開發對接中需要以下參數)
//支付寶網關地址:https://openapi.alipay.com/gateway.do
//支付寶申請的APPID
//商戶應用私鑰(與支付寶數據交互時,保證數據安全，防止數據被篡改)
//支付寶公鑰(與支付寶數據交互時，保證數據安全,防止數據被篡改)
//簽名算法類型(RSA2或者RSA,支付寶推薦使用RSA2)
//編碼格式(utf-8,gb2312,gbk)
詳細接口或參數說明，以支付寶官方文檔為准， 支付寶API網址(
https://opendocs.alipay.com/apis)
一.手機網站支付(H5版)
1.導入支付寶提供的jar，此為Maven版
<dependency>
<groupId>com.alipay.sdk</groupId>
<artifactId>alipay-sdk-java</artifactId>
<version>4.9.124.ALL</version>
</dependency>
2.關鍵支付代碼
//網關地址,APPID,商戶應用私鑰,數據格式,編碼格式,支付寶公鑰,簽名算法類型 AlipayClient alipayClient = new DefaultAlipayClient(aliPayGateway,appID,rsa_private_key,format,charset,alipayPublicKey,signType);
//不同支付類型需使用不同的請求對象 AlipayTradeWapPayRequest request = new AlipayTradeWapPayRequest(); //請求參數集合對象,除了公共參數之外,所有參數都可通過此對象傳遞（不同支付類型需使用不同的請求參數對象） AlipayTradeWapPayModel model = new AlipayTradeWapPayModel(); //訂單描述 model.setBody("訂單描述"); //訂單標題 model.setSubject("顯示效果見於下圖的標題"); //商戶訂單號 model.setOutTradeNo(orderNo); //訂單的過期時長(取值為5m - 15d,即五分鍾到十五天) model.setTimeoutExpress("30m"); //訂單總金額 model.setTotalAmount(String.valueOf(cashNum)); //產品碼 QUICK_WAP_WAY:無線快捷支付產品 model.setProductCode("QUICK_MSECURITY_PAY"); //用戶付款中途退出返回商戶網站的地址 model.setQuitUrl("https://wwww.baidu.com"); request.setBizModel(model); //支付成功后的跳轉地址 request.setReturnUrl("支付成功之后的跳轉地址"); //支付成功后的回調地址（此地址必須為公網地址，用於支付寶收到用戶付款之后,通知我們的服務端,我們可以在此接口中更改訂單狀態為已付款或后續操作） request.setNotifyUrl(aliPayNotifyUrl); String orderStr = ""; AlipayTradeWapPayResponse responseH5 = null; try { responseH5 = alipayClient.pageExecute(request); } catch (AlipayApiException e) { return ReturnUtils.returnVal(CommonConstants.appCode.UNKNOWNERROR.get(),null); } orderStr = responseH5.getBody(); Map<String, String> result = new HashMap<String, String>(); result.put("orderStr", orderStr); result.put("outTradeNo", orderNo); return ReturnUtils.returnVal(CommonConstants.appCode.SUCCESS.get(), result);
3.響應返回參數(為支付的form表單,前端解析此表單即可)
{ "code": 49000, "msg": "操作成功", "result": { "orderStr": "<form name=\"punchout_form\" method=\"post\" action=\"https://openapi.alipay.com/gateway.do?charset=utf-8&method=alipay.trade.wap.pay&sign=

二.APP支付
1.跟手機網站支付一樣，需要如下參數
2.支付寶APP支付關鍵代碼
//支付寶網關地址:https://openapi.alipay.com/gateway.do
//支付寶申請的APPID
//商戶應用私鑰(與支付寶數據交互時,保證數據安全，防止數據被篡改)
//支付寶公鑰(與支付寶數據交互時，保證數據安全,防止數據被篡改)
//簽名算法類型(RSA2或者RSA,支付寶推薦使用RSA2)
//編碼格式(utf-8,gb2312,gbk)
//網關地址,APPID,商戶應用私鑰,數據格式,編碼格式,支付寶公鑰,簽名算法類型
AlipayClient alipayClient = new DefaultAlipayClient(aliPayGateway,appID,rsa_private_key,format,charset,alipayPublicKey,signType);
//不同支付方式需使用不同的請求對象 AlipayTradeAppPayRequest request = new AlipayTradeAppPayRequest();
//請求參數集合對象,除了公共參數之外,所有參數都可通過此對象傳遞（不同支付類型需使用不同的請求參數對象） AlipayTradeAppPayModel model = new AlipayTradeAppPayModel(); model.setBody("訂單描述"); model.setSubject("訂單標題");
//訂單編號，此訂單號不可重復 model.setOutTradeNo(getTradeNo()); //設置過期時間 model.setTimeoutExpress("30m"); model.setProductCode("QUICK_WAP_WAY"); model.setTotalAmount(String.valueOf(cashNum)); request.setBizModel(model); //設置回調地址 request.setNotifyUrl("支付成功后，支付寶來回調的地址,此地址必須為公網地址,否則出現調不通"); String orderStr = ""; AlipayTradeAppPayResponse response1 = null; try { response1 = alipayClient.sdkExecute(request); } catch (AlipayApiException e) { return ReturnUtils.returnVal(CommonConstants.appCode.UNKNOWNERROR.get(), null); } orderStr = response1.getBody(); Map<String, String> result = new HashMap<String, String>(); result.put("orderStr", orderStr); result.put("outTradeNo", getTradeNo()); return ReturnUtils.returnVal(CommonConstants.appCode.SUCCESS.get(), result);
3.APP支付響應參數
//此響應信息為自己包裝過的數據，result數據返回至APP即可
{ "code": 49000, "msg": "操作成功", "result": { "orderStr": "alipay_sdk=alipay-sdk-java-dynamicVersionNo&app_id=2021001181677544&biz_content=%7B%22body%22%3A%2223212%22%2C%22out_trade_no%22%3A%22d89006ef-630b-41e5-a78e-3fee47e72506%22%2C%22product
