当 Java Spring Boot 需要 libzstd-jni.dylib 时，如何在 M1 mac 上运行它？

Question

在我的 Apple M1 笔记本电脑上，我尝试运行 Spring Boot，但收到错误：

java.lang.UnsatisfiedLinkError: no zstd-jni in java.library.path: /Users/me/Library/Java/Extensions:/Library/Java/Extensions:/Network/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java:.
Unsupported OS/arch, cannot find /darwin/aarch64/libzstd-jni.dylib or load zstd-jni from system libraries. Please try building from source the jar or providing libzstd-jni in your system.

在 Mac 上，我没有

/darwin/aarch64/

文件夹，并且找不到安装或下载的位置

libzstd-jni.dylib

。

我通过 Arm 64 DMG 安装程序安装了 Java

$ java -version 

- java version "17.0.2" 2022-01-18 LTS
- Java(TM) SE Runtime Environment (build 17.0.2+8-LTS-86)
- Java HotSpot(TM) 64-Bit Server VM (build 17.0.2+8-LTS-86, mixed mode, sharing)

JDK中的

MasOS

文件夹下有一个libjli.dylib文件：

/Library/Java/JavaVirtualMachines/jdk-17.0.2.jdk/Contents/MacOS/libjli.dylib

我将

libjli.dylib

添加到

/Library/Java/Extensions/

，但这没有帮助。

我别无选择。如果有人可以帮助我，我将非常感激。

Answer 1

这是官方存储库：https://github.com/luben/zstd-jni

在二进制版本中我看到对 aarch64 的支持。我会尝试升级到最新版本：

implementation 'com.github.luben:zstd-jni:1.5.2-1'

（我没有这种问题，这只是一个猜测——如果有帮助请告诉我。）

Answer 2

我在运行单元测试时遇到了同样的问题：

Exception in thread "pool-3-thread-1" java.lang.UnsatisfiedLinkError: no zstd-jni-1.5.6-7 in java.library.path: /Users/<user>/Library/Java/Extensions:/Library/Java/Extensions:/Network/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java:.
Unsupported OS/arch, cannot find /darwin/aarch64/libzstd-jni-1.5.6-7.dylib or load zstd-jni-1.5.6-7 from system libraries. Please try building from source the jar or providing libzstd-jni-1.5.6-7 in your system.

我忘记将 testImplementation 作为我的 build.gradle 依赖项的一部分包含在内，这解决了我的问题：

dependencies {
    implementation "com.github.luben:zstd-jni:VERSION@aar"
    testImplementation "com.github.luben:zstd-jni:VERSION"
}
