获取PC硬件信息方法一：利用Java Applet

浏览数：52 / 时间：2015年06月11日

Java Applet可以运行在网页上面，实现功能是通过调用Java来获取本地硬盘信息，前提是本机必须安装Java环境才能运行，不然会提示你安装。

下面是代码：

package com.test;

import java.applet.Applet;
import java.awt.Graphics;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileWriter;
import java.io.InputStreamReader;
import java.net.InetAddress;
import java.net.NetworkInterface;

public class HardWareUtils extends Applet{

	public HardWareUtils(){
	}
	private static final long serialVersionUID = 1L;

	@Override
	public void paint(Graphics paint) {
		super.paint(paint);
		paint.drawString("获取硬件信息", 10, 10);
		paint.drawString("CPU  SN:" + HardWareUtils.getCPUSerial(), 10, 30);
		paint.drawString("主板  SN:" + HardWareUtils.getMotherboardSN(), 10, 50);
		paint.drawString("C盘   SN:" + HardWareUtils.getHardDiskSN("c"), 10, 70);
		paint.drawString("MAC  SN:" + HardWareUtils.getMac(), 10, 90);
	}

	/**
	 * 获取主板序列号
	 * 
	 * @return
	 */
	public static String getMotherboardSN() {
		String result = "";
		try {
			File file = File.createTempFile("realhowto", ".vbs");
			file.deleteOnExit();
			FileWriter fw = new java.io.FileWriter(file);
			String vbs = "Set objWMIService = GetObject(\"winmgmts:\\\\.\\root\\cimv2\")\n"
					+ "Set colItems = objWMIService.ExecQuery _ \n"
					+ "   (\"Select * from Win32_BaseBoard\") \n"
					+ "For Each objItem in colItems \n"
					+ "    Wscript.Echo objItem.SerialNumber \n"
					+ "    exit for  ‘ do the first cpu only! \n" + "Next \n";

			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();
	}

	/**
	 * 获取硬盘序列号
	 * 
	 * @param drive
	 *            盘符
	 * @return
	 */
	public static String getHardDiskSN(String drive) {
		String result = "";
		try {
			File file = File.createTempFile("realhowto", ".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();
	}

	/**
	 * 获取CPU序列号
	 * 
	 * @return
	 */
	public static String getCPUSerial() {
		String result = "";
		try {
			File file = File.createTempFile("tmp", ".vbs");
			file.deleteOnExit();
			FileWriter fw = new java.io.FileWriter(file);
			String vbs = "Set objWMIService = GetObject(\"winmgmts:\\\\.\\root\\cimv2\")\n"
					+ "Set colItems = objWMIService.ExecQuery _ \n"
					+ "   (\"Select * from Win32_Processor\") \n"
					+ "For Each objItem in colItems \n"
					+ "    Wscript.Echo objItem.ProcessorId \n"
					+ "    exit for  ‘ do the first cpu only! \n" + "Next \n";
			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();
			file.delete();
		} catch (Exception e) {
			e.fillInStackTrace();
		}
		if (result.trim().length() < 1 || result == null) {
			result = "无CPU_ID被读取";
		}
		return result.trim();
	}

	/**
	 * 获取MAC地址
	 */
	public static String getMac() {
		try {
			byte[] mac = NetworkInterface.getByInetAddress(InetAddress.getLocalHost()).getHardwareAddress();
			StringBuffer sb = new StringBuffer();
			for (int i = 0; i < mac.length; i++) {
				if (i != 0) {
					sb.append("-");
				}
				String s = Integer.toHexString(mac[i] & 0xFF);
				sb.append(s.length() == 1 ? 0 + s : s);
			}
			return sb.toString().toUpperCase();
		} catch (Exception e) {
			return "";
		}

	}
}

运行效果如下：
