fullPublicKeyModel 和 strictlyNeedWechatPaySerial 配置项在 Spring Boot Starter 和 Solon 插件中缺失，导致用户通过配置文件设置完全公钥模式后仍会调用平台证书下载接口。

修复内容

• Spring Boot Starter (wx-java-pay-spring-boot-starter)

  • WxPayProperties 添加 strictlyNeedWechatPaySerial 和 fullPublicKeyModel 属性
  • WxPayAutoConfiguration 添加属性到 WxPayConfig 的映射

• Solon 插件 (wx-java-pay-solon-plugin)

  • WxPayProperties 添加缺失的配置项：notifyUrl、payScorePermissionNotifyUrl、publicKeyId、publicKeyPath、apiHostUrl、strictlyNeedWechatPaySerial、fullPublicKeyModel
  • WxPayAutoConfiguration 添加所有新属性的映射

使用示例

wx:
  pay:
    mch-id: 商户号
    apiv3-key: APIv3密钥
    private-key-path: classpath:cert/apiclient_key.pem
    public-key-id: 公钥ID
    public-key-path: classpath:cert/pub_key.pem
    full-public-key-model: true
    strictly-need-wechat-pay-serial: true
