Java中获取windows、Linux和windows7的MAC地址
今天在完成任务的时候,遇到了需要对对应的MAC地址进行验证的方法,以为很简单就能过,鼓捣了半天以后才发现,我的机器是window7,查询出来是乱码,居然不给支持。没办法在网上继续找资料。终于找到了,贴上来,以备不时之需。东西都有注释,自己看吧,
import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.net.InetAddress;import java.net.NetworkInterface;/** * 与系统相关的一些常用工具方法. ** @author lvbogun * @version 1.0.0 */public class SystemTool {/** * 获取当前操作系统名称. return 操作系统名称 例如:windows xp,linux 等. */public static String getOSName() {return System.getProperty("os.name").toLowerCase();}/** * 获取unix网卡的mac地址. 非windows的系统默认调用本方法获取. * 如果有特殊系统请继续扩充新的取mac地址方法. ** @return mac地址 */public static String getUnixMACAddress() {String mac = null;BufferedReader bufferedReader = null;Process process = null;try {// linux下的命令,一般取eth0作为本地主网卡process = Runtime.getRuntime().exec("ifconfig eth0");// 显示信息中包含有mac地址信息bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));String line = null;int index = -1;while ((line = bufferedReader.readLine()) != null) {// 寻找标示字符串index = line.toLowerCase().indexOf("hwaddr");if (index >= 0) {// 找到了// 取出mac地址并去除2边空格mac = line.substring(index + "hwaddr".length() + 1).trim();break;}}} catch (IOException e) {e.printStackTrace();} finally {try {if (bufferedReader != null) {bufferedReader.close();}} catch (IOException e1) {e1.printStackTrace();}bufferedReader = null;process = null;}return mac;}/** * 获取widnows网卡的mac地址. ** @return mac地址 */public static String getWindowsMACAddress() {String mac = null;BufferedReader bufferedReader = null;Process process = null;try {// windows下的命令,显示信息中包含有mac地址信息process = Runtime.getRuntime().exec("ipconfig /all");bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));String line = null;int index = -1;while ((line = bufferedReader.readLine()) != null) {System.out.println(line);// 寻找标示字符串 mac = NetworkInterface.getByInetAddress(ia).getHardwareAddress();// 下面代码是把mac地址拼装成StringStringBuffer sb = new StringBuffer();for (int i = 0; i < mac.length; i++) {if (i != 0) {sb.append("-");}// mac & 0xFF 是为了把byte转化为正整数String s = Integer.toHexString(mac & 0xFF);sb.append(s.length() == 1 ? 0 + s : s);}// 把字符串所有小写字母改为大写成为正规的mac地址并返回return sb.toString().toUpperCase();}/** * 测试用的main方法. ** @param argc 运行参数. * @throws Exception */public static void main(String[] argc) throws Exception {String os = getOSName();System.out.println(os);if (os.equals("windows 7")) {String mac = getMACAddress();System.out.println(mac);} else if (os.startsWith("windows")) {// 本地是windowsString mac = getWindowsMACAddress();System.out.println(mac);} else {// 本地是非windows系统 一般就是unixString mac = getUnixMACAddress();System.out.println(mac);}}}
找了很多都是只支持window和linux的。windows7 因为是中文,不能用同一个方法获取。只能另想办法了
