在我的 Windows 應用程序中，我想使用 FTP 刪除服務器上的目錄結構SimpleFileVisitor<Path>。它因“找不到文件”而失敗，因為在下面的代碼中，分隔符更改為反斜杠。顯然，服務器希望它是正斜杠。我怎樣才能讓它保持正斜杠？public class FTPTest {static String server ;static int port ;static String user ;static String pass; static FTPClient theFtpClient;public FTPTest(){    server = "nx.dnslinks.net";    port = 21;    user = "xxxx";    pass = "#xxxxx";     theFtpClient = new FTPClient();}static void deleteDirectoryWalkTree(Path path) throws IOException {FileVisitor visitor = new SimpleFileVisitor<Path>() {    @Override    public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) throws IOException {      Files.delete(file);      return FileVisitResult.CONTINUE;    }    @Override    public FileVisitResult visitFileFailed(Path file, IOException exc) throws IOException {      Files.delete(file);      return FileVisitResult.CONTINUE;    }    @Override    public FileVisitResult postVisitDirectory(Path dir, IOException exc) throws IOException {      if (exc != null) {        throw exc;      }      Files.delete(dir);      return FileVisitResult.CONTINUE;    }};    Files.walkFileTree(path, visitor);}    public static void main(String[] args) {    FTPTest     theFTPTest = new FTPTest();    Path Path = Paths.get("/httpdocs/manual-uploads/TestingFTPUtil/SubDir_1/SubDir_2");    try {        theFTPTest.deleteDirectoryWalkTree(Path);    } catch (IOException ex) {        Logger.getLogger(FTPTest.class.getName()).log(Level.SEVERE, null, ex);    }}}
