java服務端–支付寶APP支付接口
java服務端–支付寶APP支付接口1、首先設置支付寶賬戶有關信息及返回路徑
/**說明:
*以下代碼只是爲了方便商戶測試而提供的樣例代碼,商戶可以根據自己網站的需要,按照技術文檔編寫,並非一定要使用該代碼。
*該代碼僅供學習和研究支付寶接口使用,只是提供一個參考。

//合作身份者ID,簽約賬號,以2088開頭由16位純數字組成的字符串,查看地址:https://openhome.alipay.com/platform/keyManage.htm?keyType=partner
public static String partner = "2**************1";
//商戶的私鑰,需要PKCS8格式,RSA公私鑰生成:https://doc.open.alipay.com/doc2/detail.htm?spm=a219a.7629140.0.0.nBDxfy&treeId=58&articleId=103242&docType=1

2、支付寶APP支付–申請支付請求參數
[申請支付請求參數說明] (https://doc.open.alipay.com/docs/doc.htm?spm=a219a.7629140.0.0.O57CIo&treeId=193&articleId=105465&docType=1)
@ResponseBody
@RequestMapping(value = "/alipay.do", produces = "text/html;charset=UTF-8",method={RequestMethod.GET})
public static String alipay(String body, String subject, String out_trade_no, String total_amount) throws Exception {

//最後對請求字符串的所有一級value(biz_content作爲一個value)進行encode,編碼格式按請求串中的charset爲準,沒傳charset按UTF-8處理
map4.put("biz_content", URLEncoder.encode(bizcontentJson.toString(), "UTF-8"));
Map par = AlipayCore.paraFilter(map4); //除去數組中的空值和簽名參數
