Spring Api-网关：（M1）java.lang.UnsatisfiedLinkError：no.netty_resolver_dns_native_macos_aarch_64

Question

只是为了澄清这只发生在 M1 Mac 上，intel 版本似乎没有这个问题。

问题：

java.lang.UnsatisfiedLinkError尝试通过 API 网关访问其中一个微服务时抛出异常。 例如http://localhost:8082/API-USER/users/status/ok会抛出这个异常。

return值是正确的，API-Gateway 继续运行，尽管有烦人的异常。

问题

有谁知道如何减轻这个错误？

我累了...

• https://github.com.netty.netty-tcnative/issues/576
• https://github.com.netty.netty-tcnative/issues/343

这两个链接都建议添加netty-tcnative-boringssl-static依赖项，但效果不佳......

API网关： build.gradle

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    implementation 'org.springframework.cloud:spring-cloud-starter-gateway'
    implementation 'org.springframework.cloud:spring-cloud-starter-netflix-eureka-client'
    developmentOnly 'org.springframework.boot:spring-boot-devtools'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'

    // https://mvnrepository.com/artifact/io.netty/netty-tcnative-boringssl-static
    implementation group: 'io.netty', name: 'netty-tcnative-boringssl-static', version: '2.0.51.Final'


}

Thanks for helping

Answer 1

在 GitHub 上发现一个问题： https ://github.com/netty/netty/issues/11020

获取最新版本： https ://mvnrepository.com/artifact/io.netty/netty-resolver-dns-native-macos

仍然没有解释为什么会出现这个问题，但它为我解决了这个问题：

马文

        <dependency>
          <groupId>io.netty</groupId>
          <artifactId>netty-resolver-dns-native-macos</artifactId>
          <version>XXX</version>
          <classifier>osx-aarch_64</classifier>
        </dependency>

摇篮

implementation group: 'io.netty', name: 'netty-resolver-dns-native-macos', version: 'xxx', classifier: 'osx-aarch_64'

Answer 2

您必须将正确的分类器添加到 netty-resolver-dns-native-macos 工件，以便加载正确版本的本机库：

implementation("io.netty:netty-resolver-dns-native-macos:4.1.75.Final") {
    artifact {
        classifier = "osx-aarch_64"
    }
}

Answer 3

对于 Maven，解决方法如下所示：

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-webflux</artifactId>
        <exclusions>
            <exclusion>
                <groupId>io.netty</groupId>
                <artifactId>netty-resolver-dns-native-macos</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>io.netty</groupId>
        <artifactId>netty-resolver-dns-native-macos</artifactId>
        <version>4.1.73.Final</version>
        <classifier>osx-aarch_64</classifier>
    </dependency>

首先排除引用的库。 然后用分类器显式添加它。 在 M2 芯片 MacBook Pro 2022 上工作。

Answer 4

对我来说，在接受的答案中添加依赖项是不够的。 我正在使用 Spring Boot，但它仍然抱怨缺少：

Caused by: java.io.FileNotFoundException: META INF/native/libnetty_resolver_dns_native_macos_aarch_64.jnilib

我需要复制

/target/asr-reactive-example-1.0-SNAPSHOT.jar/BOOT-INF/classes/netty-resolver-dns-native-macos-4.1.75.Final-osx-aarch_64.jar/META-INF/native

文件夹，到：

/target/asr-reactive-example-1.0-SNAPSHOT.jar/META-INF

其中包含文件： libnetty_resolver_dns_native_macos_aarch_64.jnilib

当然它可以用maven自动化，但我不知道这是否是解决方案。

在配备Apple M1 Pro芯片的Macbook Pro上：

# Groovy

# Kotlin
runtimeOnly("io.netty:netty-resolver-dns-native-macos:4.1.80.Final:osx-aarch_64")

# Maven
<dependency>
