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;)V
org.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）
