在JSch中使用channelsftp传输文件夹和子文件夹？

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channelsftp.put(src,dest)但这对文件夹不起作用（至少我无法使其工作）。 那么有人可以解释我如何使用channelsftp传输文件夹和子文件夹？

Answer 1

要在jsch中使用多级文件夹结构，您：

1. 进入他们;
2. 列出他们的内容;
3. 每个找到的项目都要做;
4. 如果找到子文件夹，请重复1,2和3。

在你的JSCH类中下载dirs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 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. } } } 

在JSCH类中删除dirs方法：

 try { sftpChannel.cd(dir); Vector 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."); } 

从外面调用这些方法，如：

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

上面的代码（由zon）按照我的理解工作下载。我需要上传到远程服务器。我写下面的代码来实现相同的。如果有任何问题请尝试发表评论（它忽略以“。”开头的文件）

 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
