多应用多平台支付模块-微信V2JsApi支付

支付模块

此前，已设计过多应用多平模块的基础开篇 。
本篇，准备对接微信V2JsApi支付基础模块，并基于此模块实现具体的业务功能逻辑 。
开发思路如下

多应用多平台支付模块-微信V2JsApi支付

文章插图
 
微信下单网络请求配置定义微信统一下单网络请求配置，提供实现类进行调用获取下单数据 。
package com.threeox.biz.order.config;import com.threeox.biz.order.entity.wx.WxOrderInfo;import com.threeox.drivenlibrary.engine.annotation.base.ParamConfig;import com.threeox.drivenlibrary.engine.annotation.request.NETWorkRequestConfig;import com.threeox.drivenlibrary.engine.annotation.request.RequestConfig;import com.threeox.drivenlibrary.engine.annotation.scan.RequestScanConfig;import com.threeox.drivenlibrary.enums.dictionary.DataType;import com.threeox.drivenlibrary.enums.dictionary.RequestMethod;/** * 支付请求配置 * * @author 赵屈犇 * @version 1.0 * @date 创建时间: 2022/4/23 16:54 */@RequestScanConfigpublic class PayRequestConfig {/*** 微信统一下单*/@RequestConfig(requestName = "统一下单", netWorkConfig = @NetWorkRequestConfig(rootUrl = "https://api.mch.weixin.qq.com/", serverUrl = "pay/unifiedorder",parsingRespDataType = DataType.XML, responseClass = WxOrderInfo.class, methodType = RequestMethod.POST_XML, body = {@ParamConfig(paramCode = "Appid", valueCode = "appid"),@ParamConfig(paramCode = "mch_id", valueCode = "mch_id"),@ParamConfig(paramCode = "nonce_str", valueCode = "nonce_str"),@ParamConfig(paramCode = "sign", valueCode = "sign"),@ParamConfig(paramCode = "sign_type", valueCode = "sign_type"),@ParamConfig(paramCode = "body", valueCode = "body"),@ParamConfig(paramCode = "detail", valueCode = "detail"),@ParamConfig(paramCode = "out_trade_no", valueCode = "out_trade_no"),@ParamConfig(paramCode = "fee_type", valueCode = "fee_type"),@ParamConfig(paramCode = "openid", valueCode = "openid"),@ParamConfig(paramCode = "total_fee", valueCode = "total_fee"),@ParamConfig(paramCode = "notify_url", valueCode = "notify_url"),@ParamConfig(paramCode = "trade_type", valueCode = "trade_type"),@ParamConfig(paramCode = "product_id", valueCode = "product_id"),@ParamConfig(paramCode = "spbill_create_ip", valueCode = "spbill_create_ip"),}))public static final String WX_API_PLACE_ORDER = "COM.THREEOX.BIZ.ORDER.CONFIG.PAYREQUESTCONFIG.WX_API_PLACE_ORDER";}支付方式工厂实现此工厂继承基础实现类，并实现下单子类函数 。
  • 调用微信统一下单接口
  • 处理下单返回数据，并返回至前端调用
