java获取硬盘ID以及MAC地址

为了达到软件注册，或者说软件和电脑绑定的目的，需要将电脑上的固定编号进行一系列的算法计算，并生成唯一和软件匹配的号码。

那么使用java如何达到这个目的呢？

通常做法都是通过java的Runtime来完成，通过 process的输入流，进行获取相关的信息。

下面列举具体的例子：

1、DiskUtils 获取硬盘编号

import java.io.File;
import java.io.FileWriter;
import java.io.BufferedReader;
import java.io.InputStreamReader;
class DiskUtils {
private DiskUtils() {
}
public static String getSerialNumber(String drive) {
String result = "";
try {
File file = File.createTempFile("damn", ".vbs");
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
String vbs = "Set objFSO = CreateObject(\"Scripting.FileSystemObject\")\n"
+ "Set colDrives = objFSO.Drives\n"
+ "Set objDrive = colDrives.item(\""
+ drive
+ "\")\n"
+ "Wscript.Echo objDrive.SerialNumber"; // see note
fw.write(vbs);
fw.close();
Process p = Runtime.getRuntime().exec(
"cscript //NoLogo " + file.getPath());
BufferedReader input = new BufferedReader(new InputStreamReader(
p.getInputStream()));
String line;
while ((line = input.readLine()) != null) {
result += line;
}
input.close();
} catch (Exception e) {
e.printStackTrace();
}
return result.trim();
}
}

2、MacUtils 获取MAC地址

import java.io.InputStreamReader;
import java.io.LineNumberReader;
public class MacUtils {
public static void getMac(){
try {
Process process = Runtime.getRuntime().exec("ipconfig /all");
InputStreamReader ir = new InputStreamReader(process.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
String line;
while ((line = input.readLine()) != null)
if (line.indexOf("Physical Address") > 0) {
String MACAddr = line.substring(line.indexOf("-") - 2);
System.out.println("MAC address = [" + MACAddr + "]");
}
} catch (java.io.IOException e) {
System.err.println("IOException " + e.getMessage());
}
}
}

3、测试程序：

import java.io.InputStreamReader;
import java.io.LineNumberReader;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.Enumeration;
import java.util.Vector;
public class TestMain {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
//****************获取MAC地址*****************//
System.out.println("***MAC地址***");
MacUtils.getMac();
//****************获取硬盘ID*****************//
String sn = DiskUtils.getSerialNumber("C");
System.out.println("***硬盘编号***");
System.out.println(sn);
}
}

4、执行结果（我电脑上有几个VPN，所以就有多个MAC；为了防止别人搞我的电脑，数字和字母用*号代替）

***MAC地址***
MAC address = [**-**-**-**-**-**]
MAC address = [**-**-**-**-**-**]
MAC address =[**-**-**-**-**-**]
MAC address = [**-**-**-**-**-**]
***硬盘编号***
1290******

package com.sunbin.test;

import java.io.*;

import java.util.regex.*;

public class ReadMacByJava {

private String mPhysicalAddress = "";

private int mPhysicalMacNumber = 0;

private boolean isInit = false;

public void init() {
try {
String line;
String os = System.getProperty("os.name");
Process process = null;
if (os != null && os.startsWith("Windows")) {
process = Runtime.getRuntime().exec("cmd /c ipconfig /all");
} else {
process = Runtime.getRuntime().exec("ifconfig eth0");
}
BufferedReader bufferedReader = new BufferedReader(
new InputStreamReader(process.getInputStream()));
Pattern macPattern = Pattern
.compile("([0-9A-Fa-f]{2})(-[0-9A-Fa-f]{2}){5}");
Matcher macMatcher;
boolean result;
while ((line = bufferedReader.readLine()) != null) {
if ("".equals(line)) {
continue;
}
macMatcher = macPattern.matcher(line);
result = macMatcher.find();
if (result) {
mPhysicalMacNumber++;
if ("".equals(mPhysicalAddress)) {
mPhysicalAddress = macMatcher.group(0);
} else {
mPhysicalAddress += ("," + macMatcher.group(0));
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
isInit = true;
}

public String getPhysicalAddress() {
if (isInit) {
return this.mPhysicalAddress;
} else {
return "Mac is not init.";
}
}

public static void main(String[] args){
ReadMacByJava mac = new ReadMacByJava();
mac.init();
System.out.println("MAC address :"+ mac.getPhysicalAddress());
}
}
