springboot App微信支付 springboot接入微信app支付的方法

zxkCode   2021-05-20 我要评论
想了解springboot接入微信app支付的方法的相关内容吗,zxkCode在本文为您仔细讲解springboot App微信支付的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:springboot,App微信支付,springboot,微信支付,下面大家一起来学习吧。

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

<!--xstream-->
<dependency>
    <groupId>com.thoughtworks.xstream</groupId>
    <artifactId>xstream</artifactId>
    <version>1.4.7</version>
</dependency>

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

4.请求微信支付

在很多电商的项目中都有类似保存订单,充值等一系列微信支付场景;我们需要发起支付返回给前端支付sdk;该篇博文为微信支付的博文,支付宝支付的博文我也已编写,若有兴趣的话可以去我的博文中看看,希望能帮到你。

4.1发起支付请求

    /**

     */
    @Override
    public Map<String, String> payRequest(String payType, String outTradeNo, BigDecimal totalAmount) throws Exception {
        Map<String, String> map = new HashMap<String, String>();

            case TENPAY://财付通

            default:
                break;
        }
        return map;
    }

4.1.1ConstantInfo中的内容为

/**
 * 常量
 */
public class ConstantInfo {

    //订单支付财付通回调地址
    public static String TENPAY_ORDER_CALLBACK = "http://mall.gzmhyj.com:8085/huakuEComBuyer/pay/tenPayOrderCallBack";
}

4.2订单微信支付回调

该接口为为微信异步回调提供的接口

    /** 
     * @Description: 订单微信支付回调
     *
     * @Param: [request]
     * @return: java.util.Map<java.lang.String,java.lang.String>
     * @Author: zengXianKang
     * @Date: 2019/7/28
     */
    @RequestMapping(value = "/tenPayOrderCallBack", method = RequestMethod.POST)
    @ResponseBody
    public Map<String, String> tenPayOrderCallBack(HttpServletRequest request){
        Map<String, String> map = new HashMap<String, String>();
        try {
            TenPayVO tenPayVO = payService.tenPayCallBack(request);
            payService.tenPayOrderCallBack(tenPayVO);
            map.put("return_code", "SUCCESS");
            map.put("return_msg", "OK");
        } catch (Exception e) {
            e.printStackTrace();
        }
        return map;
    }

4.2.1payService的tenPayCallBack,用于解析回调的信息,拼接TenPayVO

    /**
     * @Description: 财付通回调
     * @Param: [request]
     * @return: TenPayVO
     * @Author: zengXianKang
     * @Date: 2019/7/28
     */
    @Override
    public TenPayVO tenPayCallBack(HttpServletRequest request) throws Exception {
        InputStream inputStream = request.getInputStream();
        StringBuffer resXml = new StringBuffer();
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));
        String str;
        while ((str = bufferedReader.readLine()) != null) {
            resXml.append(str);
        }
        bufferedReader.close();
        inputStream.close();
        //logger.info("微信回调报文: " + resXml);

4.3定时任务主动查询微信支付回调,一般微信发起的异步回调都是无序不定时的,所以一般保险起见都会写一个自己的定时任务主动查询微信支付回调

     * 定时任务:每十五分钟触发一次主动调用订单支付回调
     */
    @Scheduled(cron = "0 */15 * * * ?")
    public void initiativeOrderPayCallBack(){

        try {
            payService.initiativeOrderPayCallBack();
        } catch (Exception e) {
            logger.error("timer initiativeOrderPayCallBack Error.", e);
            e.printStackTrace();
        }
    }

        for (Map<String, String> map : payNoList) {
            try {
                switch (PayTypeEnum.valueOf(map.get("payType"))) {
                    case TENPAY://财付通
                        TenPayVO tenPayVO = this.tenPayQueryCallBack(map.get("payNo"));
                        //订单回调处理
                        this.tenPayOrderCallBack(tenPayVO);
                        break;
                    default:
                        break;
                }

                e.printStackTrace();
            }

4.3.2payService的tenPayQueryCallBack,用于主动查询微信支付回调,拼接TenPayVO

    /**
