在JSch中使用channelsftp传输文件夹和子文件夹？

Question

我想使用channelsftp传输文件夹和子文件夹。我可以使用channelsftp.put(src,dest)命令成功传输文件，但这不适用于文件夹（至少我无法使其工作）。那么有人可以解释一下如何使用channelsftp传输文件夹和子文件夹？

Answer 1

要使用多级文件夹结构jsch你工作：

1. 进入他们。
2. 列出其内容;
3. 对每个找到的物品都做不到;
4. 重复1，2 & 3如果找到子文件夹。

下载迪尔斯你JSCH类中的方法：

public void downloadDir(String sourcePath, String destPath) throws SftpException { // With subfolders and all files. 
    // Create local folders if absent. 
    try { 
     new File(destPath).mkdirs(); 
    } catch (Exception e) { 
     System.out.println("Error at : " + destPath); 
    } 
    sftpChannel.lcd(destPath); 

    // Copy remote folders one by one. 
    lsFolderCopy(sourcePath, destPath); // Separated because loops itself inside for subfolders. 
} 

private void lsFolderCopy(String sourcePath, String destPath) throws SftpException { // List source (remote, sftp) directory and create a local copy of it - method for every single directory. 
    Vector<ChannelSftp.LsEntry> list = sftpChannel.ls(sourcePath); // List source directory structure. 
    for (ChannelSftp.LsEntry oListItem : list) { // Iterate objects in the list to get file/folder names. 
     if (!oListItem.getAttrs().isDir()) { // If it is a file (not a directory). 
      if (!(new File(destPath + "/" + oListItem.getFilename())).exists() || (oListItem.getAttrs().getMTime() > Long.valueOf(new File(destPath + "/" + oListItem.getFilename()).lastModified()/(long) 1000).intValue())) { // Download only if changed later. 
       new File(destPath + "/" + oListItem.getFilename()); 
       sftpChannel.get(sourcePath + "/" + oListItem.getFilename(), destPath + "/" + oListItem.getFilename()); // Grab file from source ([source filename], [destination filename]). 
      } 
     } else if (!".".equals(oListItem.getFilename() || "..".equals(oListItem.getFilename())) { 
      new File(destPath + "/" + oListItem.getFilename()).mkdirs(); // Empty folder copy. 
      lsFolderCopy(sourcePath + "/" + oListItem.getFilename(), destPath + "/" + oListItem.getFilename()); // Enter found folder on server to read its contents and create locally. 
     } 
    } 
} 

REMOVE迪尔斯方法您JSCH类中：

try { 
    sftpChannel.cd(dir); 
    Vector<ChannelSftp.LsEntry> list = sftpChannel.ls(dir); // List source directory structure. 
    for (ChannelSftp.LsEntry oListItem : list) { // Iterate objects in the list to get file/folder names. 
     if (!oListItem.getAttrs().isDir()) { // If it is a file (not a directory). 
      sftpChannel.rm(dir + "/" + oListItem.getFilename()); // Remove file. 
     } else if (!".".equals(oListItem.getFilename())) { // If it is a subdir. 
      try { 
       sftpChannel.rmdir(dir + "/" + oListItem.getFilename()); // Try removing subdir. 
      } catch (Exception e) { // If subdir is not empty and error occurs. 
       lsFolderRemove(dir + "/" + oListItem.getFilename()); // Do lsFolderRemove on this subdir to enter it and clear its contents. 
      } 
     } 
    } 
    sftpChannel.rmdir(dir); // Finally remove the required dir. 
} catch (SftpException sftpException) { 
    System.out.println("Removing " + dir + " failed. It may be already deleted."); 
} 

调用这些方法从外部，如：

MyJSCHClass sftp = new MyJSCHClass(); 
sftp.removeDir("/mypublic/myfolders"); 
sftp.disconnect(); // Disconnecting is obligatory - otherwise changes on server can be discarded (e.g. loaded folder disappears).

以上代码（由zon）根据我的unde进行下载rstanding.I需要上传到远程server.I写了下面的代码来实现same.Please尝试和评论，如果任何问题

private static void lsFolderCopy(String sourcePath, String destPath, 
      ChannelSftp sftpChannel) throws SftpException, FileNotFoundException { 
    File localFile = new File(sourcePath); 

if(localFile.isFile()) 
{ 

    //copy if it is a file 
    sftpChannel.cd(destPath); 

    if(!localFile.getName().startsWith(".")) 
    sftpChannel.put(new FileInputStream(localFile), localFile.getName(),ChannelSftp.OVERWRITE); 
} 
else{ 
    System.out.println("inside else "+localFile.getName()); 
    File[] files = localFile.listFiles(); 

    if(files!=null && files.length > 0 && !localFile.getName().startsWith(".")) 
    { 

     sftpChannel.cd(destPath); 
     SftpATTRS attrs = null; 

    //check if the directory is already existing 
    try { 
     attrs = sftpChannel.stat(destPath+"/"+localFile.getName()); 
    } catch (Exception e) { 
     System.out.println(destPath+"/"+localFile.getName()+" not found"); 
    } 

    //else create a directory 
    if (attrs != null) { 
     System.out.println("Directory exists IsDir="+attrs.isDir()); 
    } else { 
     System.out.println("Creating dir "+localFile.getName()); 
     sftpChannel.mkdir(localFile.getName()); 
    } 

    //System.out.println("length " + files.length); 

    for(int i =0;i<files.length;i++) 
     { 

     lsFolderCopy(files[i].getAbsolutePath(),destPath+"/"+localFile.getName(),sftpChannel); 

        } 

       } 
      } 

     }
