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。
