Java獲得CPU序號和網卡Mac地址

package cn.com.MAC;<br />/**<br /> * 利用Runtime call作業系統的命令，具體的命令取決於不同的作業系統，注意不要調用Runtime.getRuntime().exec(String)介面，要用 Runtime.getRuntime().exec(String[])這個介面，不然複雜命令的執行會有問題。例子如下（拿cpu個數，其他類似）：<br /> * 定義命令：<br /> * WindowsCmd ="cmd.exe /c echo %NUMBER_OF_PROCESSORS%";//windows的特殊<br /> * SolarisCmd = {"/bin/sh", "-c", "/usr/sbin/psrinfo | wc -l"};<br /> * AIXCmd = {"/bin/sh", "-c", "/usr/sbin/lsdev -Cc processor | wc -l"};<br /> * HPUXCmd = {"/bin/sh", "-c", "echo /"map/" | /usr/sbin/cstm | grep CPU | wc -l "};<br /> * LinuxCmd = {"/bin/sh", "-c", "cat /proc/cpuinfo | grep ^process | wc -l"};<br /> *<br /> * 然後判斷系統：<br /> * os = System.getProperty("os.name").toLowerCase();<br /> * 根據不同的作業系統call不同的命令。<br /> */<br />import java.io.IOException;<br />import java.io.InputStream;<br />import java.io.InputStreamReader;<br />import java.io.LineNumberReader;<br />public class GetMACAddress {<br />public String getMACAddress(String ipAddress) {<br />String str = "", strMAC = "", macAddress = "";<br />try {<br />Process pp = Runtime.getRuntime().exec("nbtstat -a " + ipAddress);<br />InputStreamReader ir = new InputStreamReader(pp.getInputStream());<br />LineNumberReader input = new LineNumberReader(ir);<br />for (int i = 1; i < 100; i++) {<br />str = input.readLine();<br />if (str != null) {<br />if (str.indexOf("MAC Address") > 1) {<br />strMAC = str.substring(str.indexOf("MAC Address") + 14,<br />str.length());<br />break;<br />}<br />}<br />}<br />} catch (IOException ex) {<br />return "Can't Get MAC Address!";<br />}<br />//<br />if (strMAC.length() < 17) {<br />return "Error!";<br />}<br />macAddress = strMAC.substring(0, 2) + ":" + strMAC.substring(3, 5)<br />+ ":" + strMAC.substring(6, 8) + ":" + strMAC.substring(9, 11)<br />+ ":" + strMAC.substring(12, 14) + ":"<br />+ strMAC.substring(15, 17);<br />//<br />return macAddress;<br />}<br />public static void main(String[] args) {<br />GetMACAddress getMACAddress = new GetMACAddress();<br />//System.out.println(getMACAddress.getMACAddress("172.18.8.225"));//00-50-56-C0-00-08<br />System.out.println("MAC地址："+getMACAddress.getMACAddress("192.168.0.101"));<br />try {<br />java.lang.Process proc = Runtime.getRuntime().exec("ipconfig /all");<br />InputStream istr = proc.getInputStream();<br />byte[] data = new byte[1024];<br />istr.read(data);<br />String netdata = new String(data);<br />System.out.println("Your Mac Address=" + procAll(netdata));<br />} catch (IOException e) {<br />System.out.println("error=" + e);<br />}<br />}<br />public static String procAll(String str) {<br />return procStringEnd(procFirstMac(procAddress(str)));<br />}<br />public static String procAddress(String str) {<br />int indexof = str.indexOf("Physical Address");<br />if (indexof > 0) {<br />return str.substring(indexof, str.length());<br />}<br />return str;<br />}<br />public static String procFirstMac(String str) {<br />int indexof = str.indexOf(":");<br />if (indexof > 0) {<br />return str.substring(indexof + 1, str.length()).trim();<br />}<br />return str;<br />}<br />public static String procStringEnd(String str) {<br />int indexof = str.indexOf("/r");<br />if (indexof > 0) {<br />return str.substring(0, indexof).trim();<br />}<br />return str;<br />}<br />}<br />

 

按照這個方法可以擷取本地MAC地址，不管你是否安裝虛擬機器都可以擷取“真正的”MAC地址，方法：

System.out.println("MAC地址："+getMACAddress.getMACAddress("192.168.0.101"));

 

還有如下一種方法：
