Springboot Couchbase应用程序无法在Windows中部署[关闭]

Question

我正在开发一个 Springboot 应用程序，它连接到远程 Couchbase 服务器以获取数据。该应用程序在我机器上的本地 Couchbase 服务器上运行良好。但是当我为远程数据库配置 API 属性时，它会抛出 java.util.concurrent.TimeoutException。以下是我的错误日志。

由于我无法找出原因，我在不同的 Windows 机器上测试了 API，所有尝试都给出了相同的错误。但是，API 在 MacOS 机器上成功启动并且工作正常。我正在使用 Java 11 和 Couchbase 企业版 6.5.0。我的springboot版本是2.0.1。任何人都可以帮助我找出原因吗？谢谢。

如果您声称它可以在 Mac 上运行，并且代码没有问题，那么问题可能出在您的公司网络策略上。通常，公司对 Windows 的配置文件与 Mac 的配置文件不同。它也可能是一个防火墙/防病毒软件，它阻止了你 PC 上的传出流量，而 Mac 没有。

要验证这一理论，请在您的 PC 上本地运行 Couchbase 服务器，看看您是否可以连接到它。
