上一篇说明app支付宝绑定，接下来是提现，调用支付宝转账接口实现提现功能

支付宝转账参数实体类：

package com.framework.loippi.plugins.aliapppay.withdrawal;

import java.math.BigDecimal;

/**
 * 支付宝转账参数实体类
 */
public class Withdrawal {
    //商户端的唯一订单号，对于同一笔转账请求，商户需保证该订单号唯一
    private String outBizNo;

    //转账标题
    private String orderTitle;

    //转账金额 取值范围[0.1,100000000]；
    private BigDecimal transAmount;

    //收款方唯一标识（支付宝用户ID）
    private String identity;

    //业务备注
    private String remark;


    public String getOutBizNo() {
        return outBizNo;
    }

    public void setOutBizNo(String outBizNo) {
        this.outBizNo = outBizNo;
    }

    public String getOrderTitle() {
        return orderTitle;
    }

    public void setOrderTitle(String orderTitle) {
        this.orderTitle = orderTitle;
    }

    public BigDecimal getTransAmount() {
        return transAmount;
    }

    public void setTransAmount(BigDecimal transAmount) {
        this.transAmount = transAmount;
    }

    public String getIdentity() {
        return identity;
    }

    public void setIdentity(String identity) {
        this.identity = identity;
    }

    public String getRemark() {
        return remark;
    }

    public void setRemark(String remark) {
        this.remark = remark;
    }

}


支付宝sdk版本：

<dependency>
    <groupId>com.alipay.sdk</groupId>
    <artifactId>alipay-sdk-java</artifactId>
    <version>4.10.140.ALL</version>
</dependency>

支付宝提现工具类（使用证书格式）：

package com.framework.loippi.plugins.aliapppay.withdrawal;


import com.alipay.api.CertAlipayRequest;
import com.alipay.api.DefaultAlipayClient;
import com.alipay.api.request.AlipayFundTransUniTransferRequest;
import com.alipay.api.response.AlipayFundTransUniTransferResponse;
import com.framework.loippi.cache.ConfigCache;


public class AliPayWithdrawalUtil {
    // 支付宝应用appid
    private static String appid = "你的应用appID";

    //支付宝应用私钥
    private static String merchantPrivateKey = "应用私钥";

    //支付宝应用公钥证书路径
    private static String appCertPublicKey = "应用公钥证书路径";

    //支付宝公钥证书路径
    private static String certPublicKey = "公钥证书路径";

    //支付宝根证书路径
    private static String rootCert = "根证书路径";

    /**
     *支付宝提现功能
     * @param withdrawal 支付宝转账参数实体类
     * @return AlipayFundTransUniTransferResponse response
     * 判断成功失败 response.isSuccess()：true 成功 ，false失败
     * 成功获取交易单号：
     *     JSONObject jsonObject = JSONObject.parseObject(response.getBody());
     *     String alipay_fund_trans_uni_transfer_response = jsonObject.getString("alipay_fund_trans_uni_transfer_response");
     *     JSONObject parseObject = JSONObject.parseObject(alipay_fund_trans_uni_transfer_response);
     * 失败获取错误结果：response.getSubMsg()
     * 成功获取交易单号：parseObject.getString("order_id")
