在我使用 ISO Writer 刻录 Cd 的程序中，由于这个链接，我的代码应该在写入后弹出 cd，因为 -e 命令行，它刻录到 cd 但写入后不弹出，我不知道是什么问题？

//Library that use to create iso file
File mkisofs = new File("lib/cdrtools/mkisofs.exe");

//The root of file that we want to write on DVD
File source = new File(new ProductUtil().getProductDir()+ "\\output\\Autorun");

//Destination that the iso file will be save on it.
File destination = source.getParentFile();

//Library that use to write iso file
File isoWriter = new File("lib/isowriter/ISOWriter.exe");


String command = mkisofs.getPath()+" -UDF -o \'"+destination.getAbsolutePath()+"\\cd.iso\' \'"+source.getAbsolutePath()+"\'";
Process createIso = Runtime.getRuntime().exec(command);
BufferedReader reader = new BufferedReader(new InputStreamReader(createIso.getErrorStream()));

String line = "";
String all = "";

while((line = reader.readLine()) != null) {
    all += line+"\r\n";
}

if(createIso.waitFor() != 0) {
    JOptionPane.showMessageDialog(null, all,"Error on creating ISO file: ("+createIso.waitFor()+")",JOptionPane.ERROR_MESSAGE);
    return null;
}

command = isoWriter.getPath()+" -s 16 -e  \""+destination.getAbsolutePath()+"\\cd.iso\"";
System.out.println(command);
Process writeIso = Runtime.getRuntime().exec(command);

这是我以这种格式添加驱动器名称时遇到的错误：

command = isoWriter.getPath()+" f: -s 16 -e  \""+destination.getAbsolutePath()+"\\cd.iso\"";

在此处输入图像描述

您可以使用ProcessBuilder代替使用 + 运算符形成命令。

//  Library that use to create iso file
                File mkisofs = new File("lib/cdrtools/mkisofs.exe");
                //  The root of file that we want to write on DVD
                File source = new File(new ProductUtil().getProductDir()+ "\\output\\Autorun");
                //  Destination that the iso file will be save on it.
                File destination = source.getParentFile();
                //  Library that use to write iso file
                File isoWriter = new File("lib/isowriter/ISOWriter.exe");
                String command[] = {mkisofs.getPath(), "-UDF", "-o", destination.getAbsolutePath()+"\\cd.iso", source.getAbsolutePath() };
                 Process createIso = new ProcessBuilder(command).start();
            BufferedReader reader = new BufferedReader(new InputStreamReader(createIso.getErrorStream()));
            String line = "";
            String all = "";
            while((line = reader.readLine()) != null){
                all += line+"\r\n";
            }
            if(createIso.waitFor() != 0){
                JOptionPane.showMessageDialog(null, all,"Error on creating ISO file: ("+createIso.waitFor()+")",JOptionPane.ERROR_MESSAGE);
                return null;
            }
            command = {isoWriter.getPath(), "-s", "16", "E:", "-e",  destination.getAbsolutePath()+"\\cd.iso"};
            System.out.println(command);
            Process writeIso = new ProcessBuilder(command).start();

我对您正在使用的库一无所知，但根据@SantoshShinde，我已将驱动器号添加到参数中。您也可以尝试跳过它以检查它是否有效。

尝试通过替换代码中的以下代码来实现这一点

            command = isoWriter.getPath()+" -s 16 -e  \""+destination.getAbsolutePath()+"\\cd.iso\"";
            System.out.println(command);
            Process writeIso = Runtime.getRuntime().exec(command);

经过 ..

         command = isoburn.exe /q D: \""+destination.getAbsolutePath()+"\\cd.iso\"";
         ProcessBuilder builder = new ProcessBuilder("cmd.exe", "/c", command);
         builder.redirectErrorStream(true);
         Process p = builder.start();
