IJPay-All文档地址
1. maven中引入开发包
<dependency>
<groupId>com.github.javen205</groupId>
<artifactId>IJPay-All</artifactId>
<version>2.2.0</version>
</dependency>
2. 创建请求需要的参数类。配置信息在application中
import lombok.Data;
import org.springframework.beans.factory.annotation.Value;
@Data
public class WxPayProperties {
/**
* 设置微信公众号或者小程序等的appid.
*/
@Value("${wx.pay.appId}")
private String appId;
/**
* 微信支付商户号.
*/
@Value("${wx.pay.mchId}")
private String mchId;
/**
* 微信支付商户密钥.
*/
@Value("${wx.pay.mchKey}")
private String mchKey;
/**
* 异步回调地址
*/
@Value("${wx.pay.notifyUrl}")
private String notifyUrl;
}
application配置文件 如下
wx:
pay:
appId: wx123242342341 # appid
mchId: 123452123 # 商户号
mchKey: U6gG1CqAqwedrfghxH8eMuDrvfXFBokr # 秘钥 微信商户平台(pay.weixin.qq.com)-->账户设置-->API安全-->密钥设置
notifyUrl: http://169b91h550.imwork.net:35084/wx/wxPayNotice #可以被外网访问的接口
3. 创建WxPayProperties实例
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class WxConfiguration {
@Bean("wxPayProperties")
public WxPayProperties wxPayProperties(){
return new WxPayProperties();
}
}
4. 构建请求体，发起统一下单请求 注意：app支付需要二次签名，很重要
// 构建请求体
Map<String, String> params = UnifiedOrderModel
.builder()
.appid(wxPayProperties.getAppId())
.mch_id(wxPayProperties.getMchId())
.nonce_str(WxPayKit.generateStr())
.body("刘志强支付")
.out_trade_no(WxPayKit.generateStr()))
.total_fee("100") // 单位是分
.spbill_create_ip("123.123.123.123") // 终端ip
.notify_url(wxPayProperties.getNotifyUrl())
.trade_type(TradeType.APP.getTradeType())
.build()
.createSign(wxPayProperties.getMchKey(), SignType.MD5);
// 发送请求
String xmlResult = WxPayApi.pushOrder(false, params);
Map<String, String> resultMap = WxPayKit.xmlToMap(xmlResult);
// 二次签名
Map<String, String> packageParams = new HashMap<String, String>();
packageParams.put("appid", resultMap.get("appid"));
packageParams.put("partnerid", wxPayProperties.getMchId());
packageParams.put("prepayid", resultMap.get("prepay_id"));
packageParams.put("package", "Sign=WXPay");
packageParams.put("noncestr", resultMap.get("nonce_str"));
packageParams.put("timestamp", System.currentTimeMillis() / 1000 + "");
String packageSign = WxPayKit.createSign(packageParams, wxPayProperties.getMchKey(), SignType.MD5);
packageParams.put("sign", packageSign);
packageParams.put("return_code","SUCCESS");
return packageParams;
5. 将packageParams发送给前端用于调起支付
6. 创建微信异步回调接口，也是在application.yml中配置的notifyUrl
@PostMapping("/wx/wxPayNotice")
public void parseOrderNotifyResult(@RequestBody String xmlData) {
Map<String, String> resultMap = WxPayKit.xmlToMap(xmlData);
// 根据resultMap处理订单业务
}
7. 获取终端ip的方法
private String getClientIp() {
String ipAddress = httpServletRequest.getRemoteAddr();
if (ipAddress.equals("127.0.0.1") || ipAddress.equals("0:0:0:0:0:0:0:1")) {
//根据网卡获取本机配置的IP地址
InetAddress inetAddress = null;
try {
inetAddress = InetAddress.getLocalHost();
} catch (UnknownHostException e) {
e.printStackTrace();
}
ipAddress = inetAddress.getHostAddress();
}
//对于通过多个代理的情况，第一个IP为客户端真实的IP地址，多个IP按照','分割
if (null != ipAddress && ipAddress.length() > 15) {
if (ipAddress.indexOf(",") > 0) {
ipAddress = ipAddress.substring(0, ipAddress.indexOf(","));
}
}
return ipAddress != null ? ipAddress : "123.12.12.123";
}
