java 判断虚拟网卡物理网卡

读取注册表方式，jregistrykey.jar与jregistrykey.dll.通过“characteristics”值确定虚拟网卡还是物理网卡。该值在注册表的位置HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\【连接索引号】\下

private static int*NCF_PHYSICAL* = 0x4;//组件是一个物理适配器

**private static int***NCF\_SOFTWARE\_ENUMERATED* = 0x2; //组件是一个软件模拟的适配器
**private static int***NCF\_VIRTUAL* = 0x1;//组件是个虚拟适配器
**private static int***NCF\_HIDDEN* = 0x8;//组件不显示用户接口
**private static int***NCF\_NO\_SERVICE* = 0x10;//组件没有相关的服务(设备驱动程序)
**private static int***NCF\_NOT\_USER\_REMOVABLE* = 0x20;//不能被用户删除(例如，通过控制面板或设备管理器)
**private static int***NCF\_MULTIPORT\_INSTANCED\_ADAPTER* = 0x40;//组件有多个端口，每个端口作为单独的设备安装。每个端口有自己的hw\_id(组件ID) 并可被单独安装，这只适合于EISA适配器
**private static int***NCF\_HAS\_UI* = 0x80;//组件支持用户接口(例如，Advanced Page或Customer Properties Sheet)
**private static int***NCF\_FILTER* = 0x400;//组件是一个过滤器

根据Characteristics值当

如果是虚拟网卡：Characteristics& NCF_VIRTUAL ==NCF_VIRTUAL

如果是物理网卡：Characteristics& NCF_PHYSICAL ==NCF_PHYSICAL

该方式会把微软回环网卡也取到，所以应添加用户接口判断，去掉环回网卡。

物理网卡：Characteristics& NCF_PHYSICAL ==NCF_PHYSICAL && Characteristics &NCF_HAS_UI ==NCF_HAS_UI
