微信支付项目实战、创建订单到支付退款代码详解
1、微信支付产品介绍
微信支付开发文档：
微信支付-开发者文档 (qq.com)
源码地址：前端后端都有

提取码: qwer
1.1、付款码支付
用户展示微信钱包内的 “ 付款码 ” 给商家，商家扫描后直接完成支付，适用于线下面对面收银的场景。
1.2、JSAPI支付
线下场所：商户展示一个支付二维码，用户使用微信扫描二维码后，输入需要支付的金额，完成支
付。
公众号场景：用户在微信内进入商家公众号，打开某个页面，选择某个产品，完成支付。
PC 网站场景：在网站中展示二维码，用户使用微信扫描二维码，输入需要支付的金额，完成支
付。
特点：用户在客户端输入支付金额
1.3、小程序支付
在微信小程序平台内实现支付的功能。
1.4、Native支付
Native 支付是指商户展示支付二维码，用户再用微信 “ 扫一扫 ” 完成支付的模式。这种方式适用于 PC 网
站。
特点：商家预先指定支付金额
1.5、APP支付
商户通过在移动端独立的 APP 应用程序中集成微信支付模块，完成支付。
1.6、刷脸支付
用户在刷脸设备前通过摄像头刷脸、识别身份后进行的一种支付方式。
2、接入指引
2.1、获取商户号
微信商户平台： https://pay.weixin.qq.com/
场景： Native 支付
步骤：提交资料 => 签署协议 => 获取商户号
2.2、获取APPID
APIV2、APIV3一个模式
步骤：登录商户平台 => 选择 账户中心 => 安全中心 => API 安全 => 设置 API 密钥
随机密码生成工具： https://suijimimashengcheng.bmcx.com/
2.5、申请商户API证书
APIv3 版本的所有接口都需要； APIv2 版本的高级接口需要（如：退款、企业红包、企业付款等）
步骤：登录商户平台 => 选择 账户中心 => 安全中心 => API 安全 => 申请 API 证书
2.6、获取微信平台证书
可以预先下载，也可以通过编程的方式获取。后面的课程中，我们会通过编程的方式来获取。
注意：以上所有 API 秘钥和证书需妥善保管防止泄露
3.微信APIv3证书
商户证书 ：
商户 API 证书是指由商户申请的，包含商户的商户号、公司名称、公钥信息的证书。
商户证书在商户后台申请： https://pay.weixin.qq.com/index.php/core/cert/api_cert#/
平台证书（微信支付平台）：
微信支付平台证书是指由 微信支付 负责申请的，包含微信支付平台标识、公钥信息的证书。商户可以使
用平台证书中的公钥进行验签。
平台证书的获取： https://pay.weixin.qq.com/wiki/doc/apiv3/wechatpay/wechatpay3_0.shtml
使用微信支付商户平台证书工具进行生成
都是对称加密需要使用的加密和解密密钥，一定要保管好，不能泄露。
API 密钥对应 V2 版本的 API
APIv3 密钥对应 V3 版本的 API

r.setCode(201);
r.setMessage("失败");
return r;
}
public R data(String key, Object value){
this.data.put(key, value);

}
定义实体类
package com.wx.entity;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import lombok.Data;
import java.util.Date;
@Data
public class BaseEntity {

@Data
@TableName("t_order_info")

private String reason;//退款原因
private String refundStatus;//退款单状态
private String contentReturn;//申请退款返回参数
private String contentNotify;//退款结果通知参数
}
定义枚举
为了开发方便，我们预先在项目中定义一些枚举。枚举中定义的内容包括接口地址，支付状态等信息
API接口地址，封装了微信支付的所有接口
package com.wx.enums.wxpay;
import lombok.AllArgsConstructor;
import lombok.Getter;
/**
* api接口地址
*/
@AllArgsConstructor
@Getter
public enum WxApiType {
/**
* Native下单
*/
NATIVE_PAY("/v3/pay/transactions/native"),
/**
* Native下单
*/
NATIVE_PAY_V2("/pay/unifiedorder"),
/**
* 查询订单
*/
ORDER_QUERY_BY_NO("/v3/pay/transactions/out-trade-no/%s"),
/**
* 关闭订单
*/
CLOSE_ORDER_BY_NO("/v3/pay/transactions/out-trade-no/%s/close"),
/**
* 申请退款
*/
DOMESTIC_REFUNDS("/v3/refund/domestic/refunds"),
/**
* 查询单笔退款
*/
DOMESTIC_REFUNDS_QUERY("/v3/refund/domestic/refunds/%s"),
/**
* 申请交易账单
*/
TRADE_BILLS("/v3/bill/tradebill"),
/**
* 申请资金账单
*/
FUND_FLOW_BILLS("/v3/bill/fundflowbill");
/**
* 类型
*/
private final String type;
}
封装了通知接口地址
package com.wx.enums.wxpay;
import lombok.AllArgsConstructor;
import lombok.Getter;
/**
* 封装了通知接口地址
*/
@AllArgsConstructor
@Getter
public enum WxNotifyType {
/**
* 支付通知
*/
NATIVE_NOTIFY("/api/wx-pay/native/notify"),
/**
* 支付通知
*/
NATIVE_NOTIFY_V2("/api/wx-pay-v2/native/notify"),
/**
* 退款结果通知
*/
REFUND_NOTIFY("/api/wx-pay/refunds/notify");
/**
* 类型
*/
private final String type;
}
退款类型
package com.wx.enums.wxpay;
import lombok.AllArgsConstructor;
import lombok.Getter;
/**
* 退款
*/
@AllArgsConstructor
@Getter
public enum WxRefundStatus {
/**
* 退款成功
*/
SUCCESS("SUCCESS"),
/**
* 退款关闭
*/
CLOSED("CLOSED"),
/**
* 退款处理中
*/
PROCESSING("PROCESSING"),
/**
* 退款异常
*/
ABNORMAL("ABNORMAL");
/**
* 类型
*/
private final String type;
}
支付类型
package com.wx.enums.wxpay;
import lombok.AllArgsConstructor;
import lombok.Getter;
/**
* 支付订单状态
*/
@AllArgsConstructor
@Getter
public enum WxTradeState {
/**
* 支付成功
*/
SUCCESS("SUCCESS"),
/**
* 未支付
*/
NOTPAY("NOTPAY"),
/**
* 已关闭
*/
CLOSED("CLOSED"),
/**
* 转入退款
*/
REFUND("REFUND");
/**
* 类型
*/
private final String type;
}
支付状态
package com.wx.enums;
import lombok.AllArgsConstructor;
import lombok.Getter;
@AllArgsConstructor
@Getter
public enum OrderStatus {
/**
* 未支付
*/
NOTPAY("未支付"),
/**
* 支付成功
*/
SUCCESS("支付成功"),
/**
* 已关闭
*/
CLOSED("超时已关闭"),
/**
* 已取消
*/
CANCEL("用户已取消"),
/**
* 退款中
*/
REFUND_PROCESSING("退款中"),
/**
* 已退款
*/
REFUND_SUCCESS("已退款"),
/**
* 退款异常
*/
REFUND_ABNORMAL("退款异常");
/**
* 类型
*/
private final String type;
}
付款类型
package com.wx.enums;
import lombok.AllArgsConstructor;
import lombok.Getter;
@AllArgsConstructor
@Getter
public enum PayType {
/**
* 微信
*/
WXPAY("微信"),
/**
* 支付宝
*/
ALIPAY("支付宝");
/**
* 类型
*/
private final String type;
}
定义MyBatis-Plus的配置文件
在 confifig 包中创建配置文件 MybatisPlusConfifig
package com.wx.config;
import org.mybatis.spring.annotation.MapperScan;
import org.mybatis.spring.annotation.MapperScans;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.annotation.EnableTransactionManagement;
@Configuration
@MapperScan("com.wx.mapper")
@EnableTransactionManagement
public class MybatisPlusConfig {
}
定义Mapper层
继承BaseMapper<>
定义业务层
定义业务层接口继承 IService<>
定义业务层接口的实现类，并继承 ServiceImpl<,>
以上配置完成才可进行业务实现！！！！！！！！！！！！！！！！！！！
业务代码实现
获取商品列表接口
在 public class ProductController 中添加一个方法
package com.wx.controller;
import com.wx.entity.Product;
import com.wx.service.ProductService;
import com.wx.vo.R;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.annotation.Resource;
import java.util.List;
@CrossOrigin
@RestController
@RequestMapping("/api/product")
@Api(tags = "商品管理")
public class ProductController {
@Resource
private ProductService productService;
@GetMapping("/list")
public R list(){
List list = productService.list();
return R.ok().data("productList",list);
}
}
结果：
定义读取支付参数配置WxPayConfig

swagger测试获取
1.引入SDK（以下均已在前面配置完成。此处讲解）
前面的依赖是完整的，已经添加
https://pay.weixin.qq.com/wiki/doc/apiv3/wechatpay/wechatpay6_0.shtml
我们可以使用官方提供的 SDK ，帮助我们完成开发。实现了请求签名的生成和应答签名的验证。
com.github.wechatpay-apiv3
wechatpay-apache-httpclient
0.3.0
2.获取商户私钥
https://github.com/wechatpay-apiv3/wechatpay-apache-httpclient （如何加载商户私钥）
上面测试中注释的部门就是获取商户私钥
3、获取签名验证器和HttpClient
证书密钥使用说明：上面的配置中已经建立，此处再说明一下
https://pay.weixin.qq.com/wiki/doc/apiv3_partner/wechatpay/wechatpay3_0.shtml
获取签名验证器
https://github.com/wechatpay-apiv3/wechatpay-apache-httpclient （定时更新平台证书功能）
平台证书：平台证书封装了微信的公钥，商户可以使用平台证书中的公钥进行验签。
签名验证器：帮助我们进行验签工作，我们单独将它定义出来，方便后面的开发。
获取 HttpClient 对象
https://github.com/wechatpay-apiv3/wechatpay-apache-httpclient （定时更新平台证书功能）
HttpClient 对象：是建立远程连接的基础，我们通过 SDK 创建这个对象。
4、API字典和相关工具
https://pay.weixin.qq.com/wiki/doc/apiv3/open/pay/chapter2_7_3.shtml
我们的项目中要实现以下所有 API 的功能。
接口规则
https://pay.weixin.qq.com/wiki/doc/apiv3/wechatpay/wechatpay2_0.shtml
微信支付 APIv3 使用 JSON 作为消息体的数据交换格式。
com.google.code.gson
gson
