Java对接JeePay支付、转账实现以及回调函数

最近公司对接了第三方支付平台JeePay，看到网上文章比较少，给大家发一篇对接微信支付的吧，支付宝也一样，更换里面的参数即可，官方文档地址：系统介绍 - 计全文档，具体的服务需要大家去搭建，并创建里面的应用，我这里只给大家展示出了代码，具体的服务搭建和创建应用大家去看下官网，下面开始实现我们的代码。

首先我们引入两个pom依赖。

<dependency>
    <groupId>com.github.wxpay</groupId>
    <artifactId>wxpay-sdk</artifactId>
    <version>0.0.3</version>
</dependency>

<dependency>
    <groupId>com.jeequan</groupId>
    <artifactId>jeepay-sdk-java</artifactId>
    <version>1.5.0</version>
</dependency>

下面我们需要在配置文件里面加上相关配置，我们可以新建一个 application-jee-pay.properties。

#这个是回调的地址，一定要能访问到我们回调的IP上面，自定义
domain-name=http://120.29.172.100:8500
#这个固定写死
api-base=https://pay.vichel.com.cn/
#商户私钥
api-key=商户的私钥，如何获取看下面截图
#商户号，看下面截图
mch-no=M1670111111
#应用ID
app-id=1111b3f0e4b05e7111111111
#转账回调地址
wx-withdrawal=${domain-name}/wxPay/result/withdrawalCallback
#支付回调地址
wx-recharge=${domain-name}/wxPay/result/wxRechargeCallback

打开jeePay运营平台，点击我们要对接的应用，点击修改，里面有应用ID和商户号，我们直接复制就可以了。随机生成出一个私钥，点击保存就可以了

基础配置类

package com.mart.web.pay;

import com.jeequan.jeepay.Jeepay;
import com.jeequan.jeepay.JeepayClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;

/**
 * JeePay配置相关
 */
@Configuration
//这里指定我们要读取的配置文件
@PropertySource("classpath:application-jee-pay.properties")
public class JeePayClientConfig {

    @Autowired
    private Environment config;

    @Bean
    public JeepayClient jeePayConfig(){
        //地址
        Jeepay.setApiBase(config.getProperty("api-base"));
        //私钥
        Jeepay.apiKey = config.getProperty("api-key");
        //商户号
        Jeepay.mchNo = config.getProperty("mch-no");
        //应用ID
        Jeepay.appId = config.getProperty("app-id");
        JeepayClient jeepayClient = JeepayClient.getInstance(Jeepay.appId, Jeepay.apiKey, Jeepay.getApiBase());
        return jeepayClient;
    }
}

下面是一些支付转账操作的模块，我给大家出了一个示例，里面的参数需要结合业务需求做相应的调整，我下面只要使用的是微信小程序支付和微信零钱的转账功能。商户可以转账到用户微信的零钱。

package com.mart.web.pay;

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.jeequan.jeepay.Jeepay;

import com.jeequan.jeepay.request.TransferOrderCreateRequest;
import com.jeequan.jeepay.response.PayOrderCreateResponse;
import com.jeequan.jeepay.response.TransferOrderCreateResponse;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import java.math.BigDecimal;
