JAVA实现微信APPV3支付保姆级教程
更新时间：2024年01月28日 09:28:22 作者：扭曲的影子
微信实现支付功能与支付宝实现支付功能是相似的,这篇文章主要介绍了JAVA实现微信APPV3支付的相关资料,文中通过代码介绍的非常详细,需要的朋友可以参考下
前言
现在Java微信支付文章五花八门 看不懂 看的懵 掺杂业务逻辑不知名的返回封装 爆红一片 不妨看看这篇
由于微信更新了0.4.9版本 部分使用微信支付会解析报错 原因是微信内置了Jackson2.13.xxx依赖会与springboot这个Jackson产生冲突 可能会无法升级依赖 因为升级了也会使用老版本依赖
解决方法需要把微信支付解析 验签等方法分离重写 目前没时间写文章
1.加入Maven依赖
<!-- 微信支付V3 目前新版本-->
<dependency>
<groupId>com.github.wechatpay-apiv3</groupId>
<artifactId>wechatpay-apache-httpclient</artifactId>
<version>0.4.7</version>
</dependency>2.创建WxV3PayConfig.java配置类
/**
* implements WXPayConfig
*/
@Data
public class WxV3PayConfig {
//平台证书序列号
public static String mchSerialNo = "xxxxxxxxxxxxxx";
//appID
public static String APP_ID = "xxxxxxxxxxxxxx";
//商户id
public static String Mch_ID = "xxxxxxxxxxxxxx";
// API V3密钥
public static String apiV3Key = "xxxxxxxxxxxxxx";
// 商户API V3私钥
public static String privateKey = "
-----BEGIN PRIVATE KEY-----
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-----END PRIVATE KEY-----";
}3.创建WXPaySignatureCertificateUtil.java 工具类
复制粘贴即可

e.printStackTrace();
}
map.put("code","USER_ACCOUNT_ABNORMAL");
map.put("message", "退款请求失败");
return map; }
}代码可复制粘贴使用 无业务逻辑代码 支付代码简洁
如果更换支付类型如：APP、二维码支付、扫码支付、JSAPI支付
请看以下示例二维码支付代码
HttpPost httpPost = new HttpPost("https://api.mch.weixin.qq.com/v3"+"/pay/transactions/native");HttpPost httpPost = new HttpPost（"这里更换"）
整体不变只需要微信返回正确状态码内处理即可 如以下返回为 二维码支付参数
//完成签名并执行请求
CloseableHttpResponse response = httpClient.execute(httpPost);
//获取返回状态
int statusCode = response.getStatusLine().getStatusCode();
if (statusCode == 200) { //处理成功
String result = EntityUtils.toString(response.getEntity(), "UTF-8");
JSONObject object = JSONObject.parseObject(result);
map.put("code",200);
map.put("message", "下单成功");
map.put("data", object);
return map;
}
map.put("code",500);
map.put("message", "下单失败");
map.put("data", response);
return map;修改方式 根据官方文档返回参数类型为准
