利用java實現提現金額到支付寶帳戶的功能

實作步驟具體如下：

（學習影片分享：java教學影片）

1、導入依賴

<dependency>
<groupId>com.alipay.sdk</groupId>
<artifactId>alipay-sdk-java</artifactId>
<version>4.9.5.ALL</version>
</dependency>

2、設定參數

3、實作方法

@ApiOperation(value = "企业转账到支付宝", httpMethod = "POST", produces = "application/json;charset=UTF-8")
@ApiImplicitParams(value = {@ApiImplicitParam(value = "*用户token", name = "token",defaultValue ="", dataType = "String",paramType="header"),
@ApiImplicitParam(value = "支付宝会员id", name = "aliuserId",defaultValue ="", dataType = "int",paramType="query",example = "0"),
@ApiImplicitParam(value = "金额", name = "money",defaultValue ="", dataType = "String",paramType="query")
})
@PostMapping("/alipay/transfer")
public Result getMoney(HttpServletRequest servletRequest,BigDecimal money,@NotNull(message = "支付宝会员id不能为空")String aliuserId){
try {
String out_biz_no = "R-" + System.currentTimeMillis() + ((long) ((Math.random() * 9 + 1) * 100000000L) + "").substring(0, 8);
//构造client
CertAlipayRequest certAlipayRequest = new CertAlipayRequest();
//设置网关地址https://openapi.alipay.com/gateway.do
certAlipayRequest.setServerUrl("https://openapi.alipay.com/gateway.do");
//设置应用AppId
certAlipayRequest.setAppId(appid);
//设置应用私钥
certAlipayRequest.setPrivateKey(zzpri);
certAlipayRequest.setFormat("json");
//设置字符集
certAlipayRequest.setCharset("UTF-8");
//设置签名类型
certAlipayRequest.setSignType("RSA2");
//设置应用公钥证书路径
certAlipayRequest.setCertPath(appcertpath);
//设置支付宝公钥证书路径
certAlipayRequest.setAlipayPublicCertPath(alicertpath);
//设置支付宝根证书路径
certAlipayRequest.setRootCertPath(rootcertpath);
//构造Client
AlipayClient alipayClient = null;
try {
alipayClient = new DefaultAlipayClient(certAlipayRequest);
} catch (AlipayApiException e) {
e.printStackTrace();
}
//实例化接口
AlipayFundTransUniTransferRequest request=new AlipayFundTransUniTransferRequest();
request.setBizContent("{" +
"\"out_biz_no\":\""+out_biz_no+"\"," +
"\"trans_amount\":\""+money+"\"," +
"\"product_code\":\"TRANS_ACCOUNT_NO_PWD\"," +
"\"biz_scene\":\"DIRECT_TRANSFER\"," +
"\"order_title\":\"转账\"," +
"\"payee_info\":{" +
"\"identity\":\""+aliuserId+"\"," +
"\"identity_type\":\"ALIPAY_USER_ID\"," +
" }," +
"\"remark\":\"单笔转账\"" +
" }");
AlipayFundTransUniTransferResponse response=null;
response = alipayClient.certificateExecute(request);
if (response.isSuccess()){
if("10000".equals(response.getCode())){
return Result.ok("转账成功");
} else {
return Result.fail(Integer.valueOf(response.getCode()),response.getSubMsg());
}
}else {
return Result.fail(Integer.valueOf(response.getCode()),response.getSubMsg());
}
}catch (Exception e){
e.printStackTrace();
return Result.error(901,"支付宝转账失败！");
}
}

注意：此功能實作需要先實作支付寶授權功能取得支付寶會員id，支付寶會員id是由2088開頭的，如果是用客戶手機號碼進行提現，就會還需要輸入客戶真實姓名。

用客戶手機號提現只是部分參數不同，程式碼如下：

request.setBizContent("{" +
"\"out_biz_no\":\""+out_biz_no+"\"," +
"\"trans_amount\":\""+money+"\"," +
"\"product_code\":\"TRANS_ACCOUNT_NO_PWD\"," +
"\"biz_scene\":\"DIRECT_TRANSFER\"," +
"\"order_title\":\"转账\"," +
"\"payee_info\":{" +
"\"identity\":\""+aliuserId+"\"," +
"\"identity_type\":\"ALIPAY_USER_ID\"," +
"\"name\":\"ALIPAY_USER_ID\"" +
" }," +
"\"remark\":\"姓名\"" +
" }");
