Java获取硬件信息

不同操作系统需要的jar包

-  linux 64 bit ----------   libsigar-amd64-linux.so
-  linux 32 bit ----------   libsigar-x86-linux.so
-  windows 64 bit ----------   sigar-amd64-winnt.dll
-  windows 32 bit ----------   sigar-x86-winnt.dll

初始化sigar的服务

@Component
public class InitServlet implements InitializingBean {

    @Override
    public void afterPropertiesSet() throws Exception {
        try { 
            String osName = System.getProperty("os.name").toLowerCase();
            if (null != osName && -1 < osName.indexOf("linux")) {
                if (System.getProperty("os.arch").indexOf("64") != -1) {
                    String path=InitServlet.class.getResource("/").getPath().toString();
                    System.load(path+"libsigar-amd64-linux.so");
                } else {
                    String path=InitServlet.class.getResource("/").getPath().toString();
                    System.load(path+"libsigar-x86-linux.so");
                }
            } else {
                //暂时注释掉想到其他方法再解决
                if (System.getenv("ProgramFiles(x86)") != null){
                    String path=InitServlet.class.getResource("/").getPath().toString();
                    System.load(path+"sigar-amd64-winnt.dll");
                } else {
                    String path=InitServlet.class.getResource("/").getPath().toString();
                    System.load(path+"sigar-x86-winnt.dll");
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

获取硬件信息举例

public static Map<String, Long> getPerformanceInfoUbuntu() {
        Sigar sigar = null ;
        Map<String, Long> map = new HashMap<String, Long>();
        try {
            sigar = new Sigar(); 
           
            CpuInfo []infos = sigar.getCpuInfoList();
 
            long totalCpuNum=infos.length; //总核数
            long totalCpuMhz=0; //总赫兹数
            
            for (int i = 0; i < infos.length; i++) {// 不管是单块CPU还是多CPU都适用
                CpuInfo info = infos[i];
                totalCpuMhz+=info.getMhz();
            }
            map.put("success", Long.parseLong("1"));
            map.put("totalCpuNum", totalCpuNum);
            map.put("totalCpuMhz", totalCpuMhz);

        } catch (SigarException e) {
            map.put("success", Long.parseLong("0"));
            e.printStackTrace();
        } finally {
            if (sigar != null){
                try {
                    sigar.close();
                    sigar = null;
                } catch (Exception e) {
                    e.printStackTrace();
                } finally {
                    sigar = null;
                }
            }
        }
        return map;
    }
