由于未安装NPN/ALPN扩展而导致云Bigtable失败

Question

尝试通过Java lib与Google Cloud Bigtable交互,并在成功创建连接对象后,发送"list"命令,我收到以下command.run()方法错误:

command.run(connection, argsList.subList(1, argsList.size()));

特别:

任何帮助将非常感谢!

有必要修改你的eclipse java run以在所有其他类/ jar之前加载alpn-boot jar.使用该行:

-Xbootclasspath/p:$(pwd)/lib/bigtable/alpn-boot-${ALPN_VERSION}.jar

有关更多信息,请参阅ALPN.

对于Maven中的单元测试,您可以查看我们的示例

更新您现在可以通过使用Netty TCNative jar使用alpn-boot w/BoringSSL我们有两个例子,当前是Managed-VM-Sample和Quickstart.有关pom.xml详细信息,请参阅MVM示例,了解如何设置pom以进行本地编译和部署.Quickstart pom显示在同一机器表单上编译和运行.我们希望尽快使用所有Java样本.
