CPU架构

使用System.getProperty方法可以获取系统相关属性，CPU架构类型可用System.getProperty("os.arch")

示例：

public class SystemProperty {  
    public static void main(String args[]) {     
    System.out.println("os_name:" + System.getProperty("os.name"));     
    System.out.println("os_arch:" + System.getProperty("os.arch"));      
} 

鲲鹏上执行结果：

[root@centos7 test]# Java SystemProperty
os_name:Linux
os_arch:aarch64

调用ManagementFactory.getOperatingSystemMXBean()方法获取。

代码示例：

import Java.lang.management.ManagementFactory;
import com.sun.management.OperatingSystemMXBean;
 
public class SystemProperty {  
    public static void main(String args[]) {     
    OperatingSystemMXBean osmxb = (OperatingSystemMXBean) ManagementF
actory.getOperatingSystemMXBean();
String osArch = osmxb.getArch();
System.out.println("osArch: " + osArch);      
} 

鲲鹏上执行结果：

[root@centos7 test]# Java SystemProperty
osArch: aarch64
