SpringBoot 在 java.library.path 错误中没有netty_transport_native_e

Question

我有一个SpringBoot应用程序，它使用一个使用Apache ActiveMQ Artemis进行通信的库。 由于某种原因，我收到以下行的错误：java.lang.UnsatisfiedLinkError：java.library.path 中没有netty_transport_native_epoll_x86_64

我不知道如何纠正这一点。我读到在一些具有类似错误的项目中，他们在pom中添加了以下行.xml

<dependency>
<groupId>io.netty</groupId>
<artifactId>netty-transport-native-epoll</artifactId>
<classifier>linux-x86_64</classifier>
</dependency>

但这并没有帮助。 我一直在测试更改我的pom中的一些依赖项.xml从库和应用程序中更改，但无法解决问题。

我包括两个pom.xml：

有什么线索吗？还有什么我应该安装的吗 谢谢

Answer 1

我认为您应该检查日志。可能在该异常之后，您会看到类似以下内容：

19:02:17.432 [Test worker] DEBUG io.netty.util.internal.NativeLibraryLoader - Successfully loaded the library /tmp/libnetty_transport_native_epoll_x86_649039721349137645772.so

这意味着一切都很好。Netty 尝试在启动时加载不同的本机实现。当某些实现加载失败时，它将在 DEBUG 级别记录异常。最终，它将找到成功加载的实现。报告并关闭了一些相关问题，例如此问题。
