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：

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"" +
" }");
