只是为了澄清这只发生在M1 Mac上，英特尔版本似乎没有这个问题。

问题：

尝试通过API网关访问其中一个微服务时引发java.lang.UnsatisfiedLinkError异常错误。例如，http://localhost:8082/API-USER/users/status/ok将引发此异常错误。
return值正确，API网关继续运行，但出现令人讨厌的异常。

问题

有人知道如何减少这个错误吗？
"我累了..."

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

您必须将适当的分类器添加到netty-resolver-dns-native-macos工件中，以便加载本机库的适当版本：

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

编辑

在尝试了上面的解决方案后，我发现它并不适合我，并且用了一个愚蠢的冗长的解决方案进行了修复，我意识到我的服务器是用Tomcat启动的，因为它引入了一个可传递的依赖项org.apache.tomcat.embed：tomcat-embed-core。

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

我不会删除这篇文章，因为其他人看到了异常，但没有观察到他们的服务器是用Tomcat启动的。
对我来说，像在接受的答案中那样添加依赖性是不够的。我正在使用Sping Boot ，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
文件夹中，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，它可以自动与maven，但我不知道这是否是解决方案。

编辑日期：

好吧，我不知道为什么接受的答案工程为其他人，但对我来说，这是真的很烦人，看到启动时的错误，我不想禁用MacOSDnsServerAddressStreamProvider或谁是日志记录错误的日志记录。
在我使用netty和jdk中的调试器进入之后，我发现它尝试使用System.loadLibrary()加载它：
load with System
搜索范围：
System search
以及：
User search
当然，它不存在。然后，它尝试在类路径中查找它，但失败了：
classpath1
classpath2
在我将库复制到META-INF/native之后，它使用类路径创建库（在System/User位置失败之后），然后将库复制到工作目录的根目录，最后成功，因为System.loadLibrary()在“."中找到了它：
found-it
现在，为了自动复制文件，我做了一些技巧：
设置某些版本：

<properties>
    <netty.dns.native.resolver.version>4.1.79.Final</netty.dns.native.resolver.version>
</properties>

然后包含相依性：

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

然后复制本机库：

<plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-dependency-plugin</artifactId>
      <version>3.3.0</version>
      <executions>
      <execution>
            <id>unpack</id>
            <phase>generate-sources</phase>
            <goals>
                  <goal>unpack</goal>
            </goals>
            <configuration>
                  <skip>${skip.aarch64.copy}</skip>
                  <artifactItems>
                  <artifactItem>
                        <groupId>io.netty</groupId>
                        <artifactId>netty-resolver-dns-native-macos</artifactId>
                        <version>${netty.dns.native.resolver.version}</version>
                        <type>jar</type>
                        <classifier>osx-aarch_64</classifier>
                        <overWrite>false</overWrite>
                        <includes>**/native/*.jnilib</includes>
                  </artifactItem>
                  </artifactItems>
                  <outputDirectory>${project.build.directory}/classes</outputDirectory>
                  <overWriteReleases>true</overWriteReleases>
                  <overWriteSnapshots>true</overWriteSnapshots>
                  <overWriteIfNewer>true</overWriteIfNewer>
            </configuration>
      </execution>
      </executions>
</plugin>

但仅当操作系统架构为ARM 64时（参见<skip>${skip.aarch64.copy}</skip>）：

<plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-antrun-plugin</artifactId>
      <version>1.8</version>
      <executions>
            <execution>
                  <phase>validate</phase>
                  <goals>
                  <goal>run</goal>
                  </goals>
                  <configuration>
                  <exportAntProperties>true</exportAntProperties>
                  <target>
                        <condition property="skip.aarch64.copy" value="true" else="false">
                              <not>
                              <equals arg1="${os.detected.arch}" arg2="aarch_64"/>
                              </not>
                        </condition>
                        <echo message="Skip AARCH-64: ${skip.aarch64.copy}"/>
                  </target>
                  </configuration>
            </execution>
      </executions>
</plugin>

对于上面“os.detected.arch”属性，我使用了：

<build>
      <extensions>
          <extension>
              <groupId>kr.motd.maven</groupId>
              <artifactId>os-maven-plugin</artifactId>
              <version>1.7.0</version>
          </extension>
      </extensions>
......
</build>

我知道。非常复杂的解决方案。如果有人有其他的解决方案，请张贴在这里。

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。然后使用分类器将其显式添加。适用于M2芯片MacBook Pro 2022。
