        Today, such a problem some time ago written test procedures, when sending files on Sftp, can be sent to the successful, but could not find the directory, is a small problem, but a headache, after careful testing found by logging in split directory that place a little problem.

Attach Code:

/**
	 * 将输入流的数据上传到sftp作为文件。文件完整路径=basePath+directory
	 * 
	 * @param basePath
	 *            服务器的基础路径
	 * @param directory
	 *            上传到该目录
	 * @param sftpFileName
	 *            sftp端文件名
	 * @param input
	 *            输入流 throws SftpException
	 */
	public boolean upload(String directory, String sftpFileName,
			InputStream input) {
		boolean ret = false;
		try {
			// sftp.cd(basePath);
			sftp.cd(directory);
			ret = true;
		} catch (SftpException e) {
			Log4jBean.logger.error("对方目录可能不存在[" + directory + "]，需要创建目录，异常信息为["
					+ e.getMessage() + "]");

			// 目录不存在，则创建文件夹
			String[] dirs = directory.split("/");
			String tempPath = "";
			for (String dir : dirs) {
				if (null == dir || "".equals(dir))
					continue;
				 tempPath+="/"+dir;
				//tempPath = dir;
				try {
					Log4jBean.logger.info("检测目录[" + tempPath + "]");
					sftp.cd(tempPath);
					ret = true;
				} catch (SftpException ex) {
					try {
						Log4jBean.logger.error("创建目录[" + tempPath + "]");
						sftp.mkdir(tempPath);
						sftp.cd(tempPath);
						Log4jBean.logger.error("进入目录[" + tempPath + "]");
						ret = true;
					} catch (SftpException e1) {
						Log4jBean.logger.error("创建目录[" + tempPath
								+ "]失败1,异常信息[" + e1.getMessage() + "]");
						ret = false;
						return ret;
					} catch (Exception e1) {
						Log4jBean.logger.error("创建目录[" + tempPath
								+ "]失败2,异常信息[" + e1.getMessage() + "]");
						ret = false;
						return ret;
					}
				} catch (Exception e1) {
					Log4jBean.logger.error("创建目录[" + tempPath + "]失败3,异常信息["
							+ e1.getMessage() + "]");
					ret = false;
					return ret;
				}
			}
			Log4jBean.logger.info("创建目录完成");
			ret = true;
		} catch (Exception e1) {
			Log4jBean.logger.error("进入目录[" + directory + "]失败,异常信息["
					+ e1.getMessage() + "]");
			ret = false;
			return ret;
		}

		try {
			sftp.put(input, sftpFileName);// 上传文件
			ret = true;
		} catch (SftpException e) {
			Log4jBean.logger.error("Sftp文件处理异常，异常信息为[" + e.getMessage() + "]");
			ret = false;
		}
		return ret;
	}

Error place:

           When this is not changed before, after checking the directory is empty, exit loop, execute the following program, then the question is, under linux, using a super administrator user is not connected to the Sftp go to send the file, hit when the relative path with a time of cycle paths directly determine each layer, it is easy to cause air to create a successful path, and will put less than the original file location. Because you use the "/" is split up, such as the relative path is file / Grgz / XXX.txt, split finish in front of the file you will find this directory is empty, did not take the lead, but if you add a file in front of / words, not divided as to Oh, because that will cause more directory create a directory from the beginning.

     So the best way is to add the absolute path, so the safest, best

    Here is the way I get the absolute path (absolute path that can be written according to their actual situation)

Here is a case before the judge directory empty exit changed to continue to the next judge sentenced a catalog of space-time, which would check a level, then it will not leak. This is very important 

Renderings:

In this case, it will create a level to check and, very good O (∩_∩) O haha ​​~.
