本文使用springboot集成微信支付服务,包含微信统一支付订单接口,以及支付回调接口等，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧
1.前戏
1.1请先完成微信APP支付接入商户服务中心
1.2详情请参考微信官方文档：https://open.weixin.qq.com/
2.application.yml文件的配置如下
#微信支付配置 tenpayconfig: #商户APPID appId: asdfg12345 #商户号 mchId: 12345678 #商户的key(API密匙) key: qwertyuiop #API支付请求地址 payUrl: https://api.mch.weixin.qq.com/pay/unifiedorder #API查询请求地址 queryUrl: https://api.mch.weixin.qq.com/pay/orderquery #package packageValue: Sign=WXPay
3.配置文件对应的TenpayConfig，若没集成lombok请自行生成get/set方法
import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.stereotype.Component; import lombok.Data; /** * @Description: 微信支付配置类 * @Param: * @return: * @Author: zengXianKang * @Date: 2019/7/28 */ @Data @Component @ConfigurationProperties(prefix = "tenpayconfig") public class TenpayConfig { //appId private String appId; //商户号 private String mchId; //商户的key(API密匙) private String key; //API支付请求地址 private String payUrl; //API查询请求地址 private String queryUrl; //Sign=WXPay private String packageValue; } 3.1新建一个TenPayVO
import java.math.BigDecimal; import lombok.Data; /** * @description: TenPayVO * @author: zengXianKang * @create: 2019-07-28 **/ @Data public class TenPayVO { //商户订单号 private String outTradeNo; //业务结果 private String resultCode; //签名方式 private String signType; //签名 private String sign; //交易类型 private String tradeType; //交易状态 private String tradeState; //商户号 private String mchId; //付款银行 private String bankType; //支付金额 private BigDecimal totalFee; //币种 private String feeType; //微信支付订单号 private String transactionId; //支付完成时间 private String timeEnd; }3.2由于微信支付和回调的报文都是xml，先在maven中添加xstream的jar依赖
com.thoughtworks.xstream xstream 1.4.7
3.3TenPayUtils工具类，直接拿去用吧，该用到的我基本都写好了，拿走不谢
