java - 如何将目录上传到 FTP？

Question

这是我的代码:

public void UploadIt(){
    org.apache.commons.net.ftp.FTPClient con = null;

    try
    {
        con = new FTPClient();
        con.connect("ftp server");

        if (con.login("username", "pass"))
        {
            con.enterLocalPassiveMode(); // important!
            con.setFileType(FTP.BINARY_FILE_TYPE);
            String data = baseDir + "/emre";

            FileInputStream in = new FileInputStream(new File(data));
            boolean result = con.storeFile("/", in);
            in.close();
            if (result) Log.v("upload result", "succeeded");
            con.logout();
            con.disconnect();
        }
    }
    catch (Exception e)
    {
        e.printStackTrace();
        Log.v(" dead","ddsd");
    }

}

我可以上传文件，但无法上传目录。当我尝试上传目录或文件夹时，它显示“...是目录”，但无法上传。

在 ftp 上创建目录后，您必须从目录递归上传文件，因为在 ftp 上创建文件夹和创建文件不能同时完成，它们是单独的命令。

public static void uploadDirectory(FTPClient ftpClient,
        String remoteDirPath, String localParentDir, String remoteParentDir)
        throws IOException {

    System.out.println("LISTING directory: " + localParentDir);

    File localDir = new File(localParentDir);
    File[] subFiles = localDir.listFiles();
    if (subFiles != null && subFiles.length > 0) {
        for (File item : subFiles) {
            String remoteFilePath = remoteDirPath + "/" + remoteParentDir
                    + "/" + item.getName();
            if (remoteParentDir.equals("")) {
                remoteFilePath = remoteDirPath + "/" + item.getName();
            }


            if (item.isFile()) {
                // upload the file
                String localFilePath = item.getAbsolutePath();
                System.out.println("About to upload the file: " + localFilePath);
                boolean uploaded = uploadSingleFile(ftpClient,
                        localFilePath, remoteFilePath);
                if (uploaded) {
                    System.out.println("UPLOADED a file to: "
                            + remoteFilePath);
                } else {
                    System.out.println("COULD NOT upload the file: "
                            + localFilePath);
                }
            } else {
                // create directory on the server
                boolean created = ftpClient.makeDirectory(remoteFilePath);
                if (created) {
                    System.out.println("CREATED the directory: "
                            + remoteFilePath);
                } else {
                    System.out.println("COULD NOT create the directory: "
                            + remoteFilePath);
                }

                // upload the sub directory
                String parent = remoteParentDir + "/" + item.getName();
                if (remoteParentDir.equals("")) {
                    parent = item.getName();
                }

                localParentDir = item.getAbsolutePath();
                uploadDirectory(ftpClient, remoteDirPath, localParentDir,
                        parent);
            }
        }
    }
}
public static boolean uploadSingleFile(FTPClient ftpClient,
        String localFilePath, String remoteFilePath) throws IOException {
    File localFile = new File(localFilePath);

    InputStream inputStream = new FileInputStream(localFile);
    try {
        ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
        return ftpClient.storeFile(remoteFilePath, inputStream);
    } finally {
        inputStream.close();
    }
}
