使用 Google Cloud Pub/Sub 消息订阅者实现时无法创建 Spring-Boot bean

Question

我正在尝试运行一个具有 Spring-Boot、具有订阅者实现的 Google Cloud Pub/Sub 的项目，它给出以下错误

    Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name \u0027pubsubProducer\u0027 defined in URL [jar:file:PubsubProducer.class]: Initialization of bean failed; nested exception is java.lang.IllegalStateException: Could not find TLS ALPN provider; no working netty-tcnative, Conscrypt, or Jetty NPN/ALPN available

我能够运行这个项目，但发生了一些变化，现在我无法在 Linux Fedora 30 机器上运行它，但在 Windows 上运行良好，我查看了可能触发此问题的原因，但他们说我有不同版本的 @ 987654322@和grpc-netty-shaded，但它们是相同的1.21.0。

另外，我只使用google-cloud-pubsub-client 并且无法控制其版本。我是否也需要在本地安装包？我在 RPM 中为 grpc 和 netty 找到了一些。

感谢您的帮助，如果您需要其他任何帮助，请发表评论。

谢谢

由于没有人回答我的问题，我将其放在以供将来参考。

因为我在 Fedora 30 上，它缺少一个库 libxcrypt-compat，安装后，构建运行成功。
