ErrorsStaticallyReferencedJniMethods：java.lang.UnsatisfiedLinkError

问题描述 投票：0回答：1

我正在运行基于 netty 的组件，并在尝试绑定绑定端口时看到 UnsatisfiedLinkError 错误。有人可以澄清一下，这个特定错误的根本原因是什么？ 我读到了有关潜在兼容性问题的信息。为了确保我没有任何版本冲突，我尝试了 netty bom、reactor bom、spring boot bom - 似乎没有解决问题。我也尝试过不同版本的netty、reactor、spring boot。

pom.xml（带有反应器 bom）：

<dependency>
    <groupId>io.projectreactor.netty</groupId>
    <artifactId>reactor-netty-core</artifactId>
</dependency>

<dependency>
    <groupId>io.projectreactor.netty</groupId>
    <artifactId>reactor-netty-http</artifactId>
</dependency>


<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.projectreactor</groupId>
            <artifactId>reactor-bom</artifactId>
            <version>2022.0.21</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

Netty 能够加载所需的库：

D 241016 032344.803 [ServerRunner] NativeLibraryLoader {} - -Dio.netty.native.workdir: /tmp (io.netty.tmpdir)

我已确定该问题是特定于环境的。我可以在一台 Linux 主机上重现它，但它在另一台 Linux 主机上运行没有任何问题。 因此，在我可以观察到该问题的主机上，由于某种原因，netty 无法调用以下本机方法：

io.netty.channel.unix.ErrorsStaticallyReferencedJniMethods.errorENETUNREACH
。 其他方法都可以，但这个方法不行。
