Apache的VFS相對路徑

Question

我嘗試使用相對路徑來獲取文件夾的使用Apache VFS的父母，但我得到「無效的相對路徑」

public static void main(String[] args) throws Exception { 
FileSystemManager fileSystemManager = VFS.getManager(); 
FileObject fileObject = fileSystemManager 
.resolveFile("sftp://myuser:mypassword@myhost/"); // works!! 
FileObject root = fileObject.resolveFile("../"); // fails!! 
FileObject fileObjects[] = root.getChildren(); 
... 

我嘗試「/ ..」，「/../」爲好吧，都有異常。父目錄的正確路徑是什麼？

P.S #getParent將不起作用，它僅適用於文件，不適用於目錄。

釘住它。

public class Test { 

    public static void main(String[] args) throws Exception { 
     FileSystemOptions opts = new FileSystemOptions(); 
     SftpFileSystemConfigBuilder.getInstance().setStrictHostKeyChecking(opts, "no"); 
     SftpFileSystemConfigBuilder.getInstance().setUserDirIsRoot(opts, false); 
     FileSystemManager fileSystemManager = VFS.getManager(); 
     FileObject fileObject = fileSystemManager 
       .resolveFile("sftp://user:password@host/",opts); 

     FileObject temp = fileObject.resolveFile("/foo/faa/frog/"); 
     FileObject fileObjects[] = temp.getChildren(); 

     try { 
      for (FileObject j : fileObjects) { 

       System.out.println(j.getName().getBaseName()); 
       j.close(); 
      } 
     } finally { 
      fileObject.close(); 
      temp.close(); 
     } 
    } 
}
