1.首先 去螞蟻金服簽約 單筆轉賬到支付寶

官方api文件  https://docs.open.alipay.com/309

2.需要的配置資訊

一.應用appid

二.生成金鑰

文件地址

https://docs.open.alipay.com/291/106130

根據文件步驟生成

上傳這裡的 應用公鑰

3.下載官方sdk 然後整合到自己專案

https://docs.open.alipay.com/54/103419/

官方例項

//例項化客戶端
AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do", APP_ID, APP_PRIVATE_KEY, "json", CHARSET, ALIPAY_PUBLIC_KEY, "RSA2");
//例項化具體API對應的request類,類名稱和介面名稱對應,當前呼叫介面名稱：alipay.open.public.template.message.industry.modify 
AlipayOpenPublicTemplateMessageIndustryModifyRequest request = new AlipayOpenPublicTemplateMessageIndustryModifyRequest();
//SDK已經封裝掉了公共引數，這裡只需要傳入業務引數
//此次只是引數展示，未進行字串轉義，實際情況下請轉義
request.setBizContent("  {" +
"    \"primary_industry_name\":\"IT科技/IT軟體與服務\"," +
"    \"primary_industry_code\":\"10001/20102\"," +
"    \"secondary_industry_code\":\"10001/20102\"," +
"    \"secondary_industry_name\":\"IT科技/IT軟體與服務\"" +
" }");
AlipayOpenPublicTemplateMessageIndustryModifyResponse response = alipayClient.execute(request); 
//呼叫成功，則處理業務邏輯
if(response.isSuccess()){
	//.....
}
 

效果如下
