现有小程序要升级改版，包括微信支付商户号 也需要换掉，新老小程序使用同一个小程序ID，但是要保证 新小程序上线前，旧小程序一直可用。比如某天凌晨12点开始版本升级，这时老小程序下线，新小程序发版上线， 保证用户对版本升级无感。 请问有办法实现吗？ 我看到有解绑商户号，但是这样会导致线上小程序无法支付，有其他办法吗？

github上描述 wechatpay-apache-httpclient 是装饰器库，但是没有找到使用装饰器的示例。比如我想接微信的native支付，我希望能找到java版demo，引入我的项目后只需要改业务逻辑和商户id、秘钥那一套配置 就能快速接入。现在有这样的DEMO吗？ --------- 找到一个比较好的例子 ： https://developers.weixin.qq.com/community/develop/article/doc/00068ab2a8c6006ba28baeb745b413
