无法在 32 位 windows 机器中创建 grpc 连接
Unable to create grpc connection in 32bit windows machine
我正在尝试使用我的 java 代码和 GCP 提供的几个库来访问我的 GCP 项目中的订阅者列表。此代码在我的 64 位 Windows 环境中运行良好，但在 32 位 windows 环境中无法运行。
我在一些文档中看到，32 位机器不支持 netty，如果需要，我们可以构建自己的二进制文件。

您回答了您自己的问题...netty-tcnative-* 不支持 32 位平台，因此您需要自己编译并将其包含在您的 class-path 中。
grpc-java SECURITY.md 描述了您的选项：
- 使用Java 9+，支持ALPN而不需要tcnative
- 对于 32 位 Windows 具体而言，您可以 Conscrypt
该文档还介绍了如何使用 Conscrypt。即添加对 conscrypt-openjdk-uber 的依赖并将其注册为默认安全提供程序：
import org.conscrypt.Conscrypt;
import java.security.Security;
...
// Somewhere in main()
Security.insertProviderAt(Conscrypt.newProvider(), 1);
