篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了谷歌扳手| java.lang.IllegalArgumentException：尚未正确配置Jetty ALPN / NPN相关的知识，希望对你有一定的参考价值。

所以我有一个我以前见过的问题但是所有使用其他修复的尝试都没有用。我对Google Spanner有疑问，更具体地说是在线：

SpannerOptions options = SpannerOptions.newBuilder().build();

我收到的堆栈错误：

我已经尝试添加maven依赖项等，但每次都没有做任何事来修复我一直接收的错误。我正在使用带有端点的应用引擎，后来这个应用引擎将启动计算引擎。这是我当前的pom.xml文件：

非常感谢您提供的任何帮助或建议。

答案

来自Google Cloud Spanner文档：

Google Compute Engine（GCE），Google App Engine - 灵活环境，Google容器引擎（GKE）和Google Cloud Functions均支持此页面中提到的Cloud Spanner客户端库。 Google App Engine支持Java Spanner客户端库 - 标准环境Java 8 Beta。

如果您使用的是Google App Engine - 标准环境Java 7或Google App Engine - 带Go，php或Python的标准环境，请使用REST界面访问Cloud Spanner。

资料来源：https://cloud.google.com/spanner/docs/reference/libraries

据我所知，您正在尝试将Java库与Java 7结合使用，这是不受支持的。
