java 转账 java转账接口

Java实现单次转账到到个人支付宝账户（新版接口）

前言：支付宝5月21日发布通知单次转账接口升级，老版接口不再维护

1.首先需要认证企业支付宝账户

2.准入条件

该能力仅对企业支付宝账户开放；

企业支付宝账户需满足注册满 90 天，且已实名认证。

3.去绑定（创建）你的应用

4.去能力列表，能力管理签约转账到支付宝账号

准备工作完成进入开发阶段

1.alipay.fund.trans.toaccount.transfer （旧版转账到支付宝账户接口/阿里已经不维护了不建议这个）

链接: https://opendocs.alipay.com/open/309/alipay.fund.trans.toaccount.transfer.

2.alipay.fund.trans.uni.transfer(单笔转账接口/这是新版)

本人用的是证书签名验证的新版转账接口，下面是代码的实现（如果不了解什么是证书签名验证点击查看链接: https://opendocs.alipay.com/open/291/105974.）

需要的maven依赖

<dependency>
   <groupId>com.alipay.sdk</groupId>
   <artifactId>alipay-sdk-java</artifactId>
   <version>4.8.73.ALL</version>
</dependency>

<dependency>
   <groupId>com.google.code.gson</groupId>
   <artifactId>gson</artifactId>
</dependency>

Controller层

@RequestMapping("/updatewithdrawal")
@ResponseBody
@CrossOrigin(origins = "*", maxAge = 3600)//跨域
public ResultMap updatewithdrawal(String id, Integer mType) throws AlipayApiException {
	//根据提现订单id查询出提现记录对象
    Withdraw w = userService.getwithdrawalsById(id);
    if (w.getmManner() == 1) {
    	//调用转账到个人支付宝
        Map<String, Object> map = alipayService.alipayWithdraw(id, w.getmMoney(),w.getuId(), w.getAccountpayeename(), w.getAccountpayee());
        return ResultMap.ok(200, "success").put("data",map);
    } else if (w.getmManner() == 2) {
    //这是微信提现
        Map<String, String> b = userService.updatewithdrawal(id,mType);
       return ResultMap.ok(200, "success").put("data",b);
    }
    return ResultMap.error(305, "提现异常");
}

    }
    return map;
}

大致看了看，目前可查的支付宝单笔转账的代码实现基本都是老版本接口，以上是新版本（单笔转账到支付宝账号/查询转账订单）的代码实现（基础版代码，可以思考如何去优化） 好记性不如烂笔头~
