        <dependency><groupId>com.github.binarywang</groupId><artifactId>weixin-java-pay</artifactId><version>4.6.0</version></dependency>

配置

wx:pay:appId: *********mchId: ********apiV3Key: ********certSerialNo: ********privateKeyPath: classpath:apiclient_key.pem #apiclient_key.pem证书文件的绝对路径或者以classpath:开头的类路径privateCertPath: classpath:apiclient_cert.pem #apiclient_cert.pem证书文件的绝对路径或者以classpath:开头的类路径
