关键是增加了： chooser.fileSelectionMode = JFileChooser.DIRECTORIES_ONLY;

        val chooser = JFileChooser()
        chooser.fileSelectionMode = JFileChooser.DIRECTORIES_ONLY;
        chooser.showOpenDialog(this@FindLostIdView)
        val file: File = chooser.selectedFile
        val absolutePath: String = file.absolutePath
        return absolutePath;
