System.out.println(LicenseUtil.getMacAddress()); //获得物理MAC地址

结果：28-D2-44-22-BE-DC

Vector<String> vector = LicenseUtil.getMacAddresses(); //获得所有MAC地址

System.out.println(StringUtils.join(vector)); 

结果：[28-D2-44-22-BE-DC, 4A-D2-24-FE-86-06, 00-50-56-C0-00-01, 00-50-56-C0-00-08, 48-D2-24-FE-86-06, 00-FF-49-2A-2D-EB]

String[] keyPair = LicenseUtil.createKeyPair(); //生成秘钥对

System.out.println(keyPair.length+" ,\n"+StringUtils.join(keyPair,"\n"));

结果：
