利用java实现提现金额到支付宝账户的功能

实现步骤具体如下：

（学习视频分享：java教学视频）

1、导入依赖

com.alipay.sdk

alipay-sdk-java

4.9.5.ALL

2、配置参数

3、实现方法

@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：该功能实现需要先实现支付宝授权功能获取支付宝会员id，支付宝会员id是由2088开头的，如果是用客户手机号进行提现，就会还需要输入客户真实姓名。

用客户手机号提现只是部分参数不同，代码如下：
