Java代码如何判断linux系统windows系统

Java代码判断linux系统windows系统

在使用硬件SDK的时候,往往有windows、linux两套。

本地开发的时候使用windows,打包发布的时候使用linux,来回切换很麻烦。

可以使用下面的判断来加载不同版本的SDK。

package Commom;
 
public class osSelect {
 
    public static boolean isLinux() {
        return System.getProperty("os.name").toLowerCase().contains("linux");
    }
 
    public static boolean isWindows() {
        return System.getProperty("os.name").toLowerCase().contains("windows");
    }
 
}

Java在Linux与windows系统下获取主板序列号,cpu序列号以及mac地址

概述:

实现了获取当前操作系统名称,主板序列号,CPU序列号,mac地址的相关方法函数。

应对的场景是信创设备无法正常识别我们的加密狗,对于软件license的限制,我们通过系统当前日期以及绑定对方设备进行限制。
