无法加载任何给定的库：[netty-tcnative-linux-x86_64，netty-tcnative]

标签： tomcat netty grpc-java

我在tomcat容器中部署了一个web应用程序，并使用了grpc-netty（1.2.0）和netty-tcnative-boringssl-static：jar：1.1.33.Fork26。

当我打开调试日志时，它会告诉“java.lang.IllegalArgumentException：无法加载任何给定的库：[netty-tcnative-linux-x86_64，netty-tcnative-linux-x86_64-fedora，netty-tcnative ]“然后出现错误消息”java.lang.IllegalArgumentException：Jetty ALPN / NPN尚未正确配置。“。

我已经浏览了https://github.com/grpc/grpc-java/blob/master/SECURITY.md的问题排查部分并验证了我的netty版本，这看起来没问题。下面是我的maven依赖列表

3 个答案:

答案 0 :(得分：2)

我找到了解决方案，我将netty-tcnative-boringssl-static升级到2.0.7，并且通过此更改，所有其他版本都必须升级（请查看https://github.com/grpc/grpc-java/blob/master/SECURITY.md中的故障排除部分中的表格）。这是我用过的清单，

grpc-netty-1.9.1.jar
netty-3.2.2.Final.jar
netty-buffer-4.1.17.Final.jar
netty-codec-4.1.17.Final.jar
netty-codec-http-4.1.17.Final.jar
netty-codec-http2-4.1.17.Final.jar
netty-codec-socks-4.1.17.Final.jar
netty-common-4.1.17.Final.jar
netty-handler-4.1.17.Final.jar
netty-handler-proxy-4.1.17.Final.jar
netty-resolver-4.1.17.Final.jar
netty-tcnative-boringssl-static-2.0.7.Final.jar
netty-transport-4.1.17.Final.jar
grpc-context-1.9.1.jar
grpc-core-1.9.1.jar
grpc-protobuf-1.9.1.jar
grpc-protobuf-lite-1.9.1.jar
grpc-stub-1.9.1.jar
opencensus-contrib-grpc-metrics-0.10.0.jar

答案 1 :(得分：1)

此问题在更新版本的netty-tcnative中得到修复，其中的类移动到另一个命名空间（2.0.x系列）。所以你应该检查哪个graph-java版本支持这些并升级。

答案 2 :(得分：0)

我通过从Java 8升级到Java 11来解决了类似的问题，因为默认情况下它具有ALPN。
