java - 在 Maven2 中使用 Sigar 的问题

Question

我在将 Sigar 与 Maven2 结合使用时遇到错误。我知道它找不到 native 库(dll 或 .so)，因为我知道我无法将 native 库复制到我的 WEB-INF/lib 目录中...我的问题是“如何将 lib 文件目录复制到我的 WAR 文件中的 WEB-INF/lib 使用 Maven？

我要复制的目录是:${basedir}/lib/我要复制到的目录是:${webapp.output}/WEB-INF/lib(我想？)

这里是错误:

java.lang.UnsatisfiedLinkError: org.hyperic.sigar.Sigar.getLoadAverage()

这是我的 pom 文件:

您可以配置 Maven war 插件来复制额外的文件/文件夹，如图所示 here .像下面这样的东西。

    <configuration>
      <webResources>
        <resource>
          <directory>lib</directory>
          <!-- override the destination directory for this resource -->
          <targetPath>WEB-INF/lib</targetPath>
        </resource>
      </webResources>
    </configuration>
