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
[java] view plain copy
- 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
[java] view plain copy
- 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：
[java] view plain copy
- 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***
