Question

我一直在尝试这段代码，但我想知道输出不是序列号（SN）。结果只包含没有字母的数字。我想知道，它必须是数字和字母之间的组合。

以下是代码：

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);
    }
}

然后，我也试图证明真实的SN可能是真的（包含数字和字母）。这是我要检查硬盘的真实SN的教程：

打开命令提示符窗口（“开始”菜单＆gt;所有程序＆gt;附件＆gt;命令提示符）。
输入：vol。
卷序列号是磁盘序列号。

代码和教程之间的结果确实有很大不同。你们知道吗，哪一个是真的？以及如何证明这一点？

您可能希望尝试更多内容：

import java.io.*;

public class SerialNumber
{
  public String executeVolCommand()
  {
    String NEWLINE = System.getProperty("line.separator");
    StringBuffer buffer = new StringBuffer();
    try{

      Process pb = new ProcessBuilder("cmd","/c", "vol").start();  
      InputStream in = pb.getInputStream();  
      BufferedReader br = new BufferedReader(new InputStreamReader(in));  
      String line;  
      while ((line = br.readLine()) != null) {  
        buffer.append(line + NEWLINE);  
      }
    }
    catch(Exception e){e.printStackTrace();}
    return buffer.toString();      }
}

然后，一旦得到结果，就可以解析它的实际序列号。希望这会有所帮助。

如果你还想要答案......

import java.io.*;
import java.util.*;

public class SerialNumber {

public static void main ( String[] args ) throws Exception {

        Process p = Runtime.getRuntime().exec ( "ioreg -l" );
        InputStream is = p.getInputStream();
        StringBuilder sb = new StringBuilder();
        int i = 0;
        while ( ( i = is.read() ) != -1 ) if ( ( char ) i != '|' && ( char ) i != ' ' ) sb.append ( ( char ) i );
        InputStream fis = new ByteArrayInputStream ( sb.toString().getBytes() );
        Properties pro = new Properties();
        pro.load ( fis );
        System.out.println ( pro.get ( "\"IOPlatformSerialNumber\"" ).toString().substring ( 1, pro.get ( "\"IOPlatformSerialNumber\"" ).toString().length() - 1 ) );

    }

}

Answer 3

 // InputStream stream = Runtime.getRuntime().exec("wmic diskdrive get name,size,model,SerialNumber ").getInputStream();
    List<String> collect;
    InputStream stream = Runtime.getRuntime().exec("wmic diskdrive get SerialNumber ").getInputStream();

    try (BufferedReader reader = new BufferedReader(new InputStreamReader(stream))) {

     collect  = reader.lines().collect(Collectors.toList());
        /*while ((line = reader.readLine()) != null) {
        model += line;
        }*/
    }
