Java獲得硬盤和主板的序列號代碼

當你需要獲得windows硬件細節時，java可能不是最好的工具。 簡直無從下手，不過可以通過VBS腳本獲得需要的數據，然后java調用VBS獲得輸出。

VBS腳本通過查詢WMI來獲得系統硬件信息。 我們需要Win32_BaseBoard類，更多可以參考 http://msdn2.microsoft.com/en-us/library/aa389273.aspx.

獲得主板信息：

import java.io.File;
import java.io.FileWriter;
import java.io.BufferedReader;
import java.io.InputStreamReader;

public class MiscUtils {
  private MiscUtils() {  }

  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();
  }

  public static void main(String[] args){
    String cpuId = MiscUtils.getMotherboardSN();
    javax.swing.JOptionPane.showConfirmDialog((java.awt.Component)
         null, cpuId, "Motherboard serial number",
         javax.swing.JOptionPane.DEFAULT_OPTION);
  }
}

獲得硬盤序列號：

import java.io.File;
import java.io.FileWriter;
import java.io.BufferedReader;
import java.io.InputStreamReader;

public class DiskUtils {
  private DiskUtils() {  }

  public static String getSerialNumber(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();
  }

  public static void main(String[] args){
    String sn = DiskUtils.getSerialNumber("C");
    javax.swing.JOptionPane.showConfirmDialog((java.awt.Component)
         null, sn, "Serial Number of C:",
         javax.swing.JOptionPane.DEFAULT_OPTION);
  }
}

說明: 還可以獲得其他更多屬性如： objDrive.AvailableSpace/DriveType/FileSystem/IsReady
