sftp上传

1、搭建本地sftp

　　1.1、下载msftpsrvr.exe软件

　　　　　　下载地址：http://www.download3k.com/Install-Core-FTP-Mini-SFTP-Server.html

　　　　　　

　　1.2、双击msftpsrvr.exe，录入sftp信息

　　　　

2、工具类

    public static void main(String[] args) throws Exception {
        SftpUploadUtil sfUtil = new SftpUploadUtil();
        String sftpHost = "10.23.10.39";
        int sftpPort = 22; // 端口表字段暂时未定义
        String sftpUserName = "quanbs";
        String password = "123456";
        String privateKey = ""; // 秘钥文件路径
        String passphrase = ""; // 秘钥口令
        ChannelSftp sftp = sfUtil.connect(sftpHost, sftpPort, sftpUserName, password, privateKey, passphrase);
    }

运行结果(连接成功)：

        String sftpHost = "10.23.10.39";

        String privateKey = ""; // 秘钥文件路径
        String passphrase = ""; // 秘钥口令
        ChannelSftp sftp = sfUtil.connect(sftpHost, sftpPort, sftpUserName, password, privateKey, passphrase);
        
        // 测试sftp上传
        testUploadFile(sfUtil, sftp);
    }

    /**
     * 测试上传文件
     * @param sfUtil
     * @param sftp
     * @throws SftpException
     */
    public static void testUploadFile(SftpUploadUtil sfUtil, ChannelSftp sftp) throws SftpException{
        String sftpDirectory = "E:"+File.separator+"sftp";
        sftpDirectory = "\";
        String uploadFile = "D:\log.zip";
        List lsList = getLsListName(File.separator, sftp); // 获取目录下的文件名List
        String date = DateUtils.convertDateToLong(new Date(), "yyyyMMdd").toString(); // 当天文件夹 20161026
        if (!lsList.contains(date)) // 当天日期文件夹不存在则创建
            sftp.mkdir(date);
        
        sftpDirectory += date;
        
        sfUtil.upload(sftpDirectory, uploadFile, sftp);
        
    }

    /**
     * 获取目录下的文件名List
     * @param path 目录
     * @param sftp
     * @throws SftpException
     */
    private static List<String> getLsListName(String path, ChannelSftp sftp) throws SftpException{
        List<String> list = new ArrayList<String>();
        Vector vector = sftp.ls(File.separator);
        Iterator<LsEntry> it = vector.iterator();
        while (it.hasNext()) {
            LsEntry lsEntry = it.next();
            list.add(lsEntry.getFilename());
        }
        return list;
    } 

运行结果：
