二、使用问题解答
第一种问题：在华为云 ARM 部署报错：org.hyperic.sigar.SigarException: no libsigar-aarch64-linux.so in java.libra
解决办法：遇到华为 ARM 服务器时，需要 libsigar-aarch64-linux.so 库支持 aarch64 平台，把“libsigar-aarch64-linux.so”放在 linux 下的 /usr/lib 和 /usr/lib64 下（都要进行拷贝）该朋友已经具体介绍，详情点击这里
第二种问题：使用该类常常会遇到问题：
java.lang.UnsatisfiedLinkError: org.hyperic.sigar.SysInfo.gather(Lorg/hyperic/sigar/Sigar;)Vorg.hyperic.sigar.SysInfo.gather(Native Method)org.hyperic.sigar.OperatingSystem.getInstance(OperatingSystem.java:90)com.shuhaiserver.page.servlet.LoginServlet.doLogin(LoginServlet.java:146)com.shuhaiserver.page.servlet.LoginServlet.doPost(LoginServlet.java:54)javax.servlet.http.HttpServlet.service(HttpServlet.java:637)javax.servlet.http.HttpServlet.service(HttpServlet.java:717)com.shuhaiserver.page.servlet.MyFilter.doFilter(MyFilter.java:82)
解决办法：第一种办法：此时，需要将 libsigar-amd64-linux.so、libsigar-x86-linux.so、sigar-amd64-winnt.dll、sigar-x86-winnt.dll、sigar-x86-winnt.lib 文件放在项目的 lib 文件夹下第二种办法：将上面的 5 个文件放在 linux 下的 /usr/lib 和 /usr/lib64 下（都要进行拷贝） -----使用场景是 linux 下启动 springboot 的 jar 包 以命令： java -jar xx.jar 运行才会这么做
补充：至于有的水友说的放在 tomcat 目录或者其他目录，因为我没碰到，需要你们自己测试
还有的朋友说放在 java.library.path 库下面，我感觉我的/usr/lib 或/usr/lib64 应该就是这个，具体是不是我不清楚（另外，查看 linux 下的 java.library.path 可新建 springboot 项目，在 Application 下新建一行打印输出，并打包在 linux 下以命令 java -jar xx.jar 运行即可显示，帖图如下）
