Spring Boot+WeChat公衆番号JSAPI支払い機能の実現

1、pom.xml依存配置

<!--      -->
<dependency>
  <groupId>com.egzosn</groupId>
  <artifactId>pay-java-wx</artifactId>
  <version>2.12.4</version>
</dependency>

2、appication.ymlファイル配置WeChat公衆番号の基礎情報

#         
wechatpay:
 mchId: #   Id
 appId: #  id
 storePassword: #      
 secretKey: #   
 notifyUrl: #      
 keyStore:  #       

3、設定プロファイル WechatPayConfig.java

package com.example.emoticon.wechat;
 
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
 
/**
 * @ClassName WechatPayConfig
 * @Description       
 * @Author WangJing
 * @Date 2021/3/23 4:38   
 * @Version V1.1.0
 */
 
@Data
@Component
@ConfigurationProperties(prefix = "wechatpay")
public class WechatPayConfig {
 
  private String mchId;//   id（   
 
  private String appId;//  id
 
  private String secretKey;//  
 
  private String notifyUrl;
  private String keyStore;//              .p12     
  private String storePassword;
 
}

4、controller論理コード

package com.example.emoticon.controller;
 
import com.egzosn.pay.common.api.PayService;
import com.egzosn.pay.common.bean.PayOrder;
import com.egzosn.pay.common.bean.RefundOrder;
import com.egzosn.pay.common.http.HttpConfigStorage;
import com.egzosn.pay.common.util.sign.SignUtils;
import com.egzosn.pay.wx.api.WxPayConfigStorage;
import com.egzosn.pay.wx.api.WxPayService;
import com.egzosn.pay.wx.bean.WxTransactionType;
import com.example.emoticon.wechat.WechatPayConfig;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
 
import javax.annotation.PostConstruct;
import javax.servlet.http.HttpServletRequest;
import java.io.IOException;
import java.math.BigDecimal;
import java.util.Date;
import java.util.Map;
