1 下载安装sigar-1.6.4.zip
使用java自带的包获取系统数据,容易找不到包,尤其是内存信息不够准确,所以选择使用sigar获取系统信息。
下载地址:http://sourceforge.net/projects/sigar/files/latest/download?source=files
解压压缩包,将lib下sigar.jar导入eclipse的CLASSPATH中,再将sigar-x86-winnt.dll存入Java的bin目录即可。
2 如果maven项目可以用坐标或者下载下来手动安装
<!-- https://mvnrepository.com/artifact/org.hyperic/sigar -->
<dependency>
<groupId>org.hyperic</groupId>
<artifactId>sigar</artifactId>
<version>1.6.4</version>
</dependency>
安装命令:mvn install:install-file -Dfile=jar包的位置 -DgroupId=上面的groupId -DartifactId=上面的artifactId -Dversion=上面的version -Dpackaging=jar
便捷安装命令:自己改下jar包的位置:mvn install:install-file -Dfile=C:\Users\Administrator\Desktop\服务器信息\hyperic-sigar-1.6.4\sigar-bin\lib\sigar.jar -DgroupId=org.hyperic -DartifactId=sigar -Dversion=1.6.4 -Dpackaging=jar
3 出现no sigar-x86-winnt.dll in java.library.path 异常
解压压缩包,将lib下sigar.jar导入eclipse的CLASSPATH中,再将sigar-x86-winnt.dll存入Java的bin目录即可。
