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:
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 ) );
}
}

// 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;
}*/
}
