如何从JFileChooser检索UNC路径而不是映射的驱动器路径

 filePath = fc.getSelectedFile().getAbsolutePath();
 Runtime runTime = Runtime.getRuntime();
 Process process = runTime.exec(\"net use\");
 InputStream inStream = process.getInputStream();
 InputStreamReader inputStreamReader = new InputStreamReader(inStream);
 BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
 String line = null;
 String[] components = null;
 while (null != (line = bufferedReader.readLine())) {
   components = line.split(\"\\\\s+\");
    if ((components.length > 2) && (components[1].equals(filePath.substring(0, 2)))) {
      filePath = filePath.replace(components[1], components[2]);
    }
 }

System.out.println(ShellFolder.getShellFolder(new File(filePath.substring(0,3))).getDisplayName());

File.listRoots();

sun.awt.shell.ShellFolder

File networkDrive = new File(\"G:\\\");
ShellFolder shellFolder = ShellFolder.getShellFolder(networkDrive);
ShellFolderColumnInfo[] cols = shellFolder.getFolderColumns();
for (int i = 0; i < cols.length; i++) {
    if (\"Attributes\".equals(cols[i].getTitle())) {
        String uncPath = (String) shellFolder.getFolderColumnValue(i);
        System.err.println(uncPath);
        break; // don\'t need to look at other columns
    }
}
