java 通過ssh連接遠程服務器

話不多說，直接上代碼

public static void sshSftp(InputStream inputStream, String fileName, String ip,
                               String user, String pwd, String port, String path) throws Exception{
        Session session = null;
        Channel channel = null;
        JSch jSch = new JSch();
        int portN = Integer.parseInt(port);

        if (Integer.parseInt(port) <= 0){
            session = jSch.getSession(user,ip);
        }else {
            session = jSch.getSession(user,ip,portN);
        }

        if (session == null){
            throw new MyException(ErrorCode.SFTP_CONNECTION_FAILED);
        }
        session.setPassword(pwd);
        session.setConfig("StrictHostKeyChecking", "no");
        session.setTimeout(30000);
        session.connect(30000);

        OutputStream outputStream = null;
        BufferedInputStream bis = null;
        String storeDocPath = fileName;
        File storeFile = new File(storeDocPath);
        try{
            channel = (Channel)session.openChannel("sftp");
            channel.connect(1000);
            ChannelSftp sftp = (ChannelSftp)channel;
            //connect to the specific dir
            sftp.cd(path);
            outputStream = sftp.put(fileName);
            bis = new BufferedInputStream(inputStream);
            int c;
            while ((c = bis.read()) != -1) {
                outputStream.write(c);
            }

        }catch (Exception e){
            System.out.println(e);
        }finally {
            //關流操作
            if(outputStream != null){
                outputStream.flush();
                outputStream.close();
            }
            if(session != null){
                session.disconnect();
            }
            if(channel != null) {
                channel.disconnect();
            }
        }
    }
