上传文件至其他服务器的几种方式

1.sftp文件上传（需要的lib文件地址：com.jcraft.jsch_0.1.55.jar ）

import java.io.File;
import java.io.FileInputStream;

import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;

public class SFtpUtils {

    public static boolean uploadFile(String host, int post, String user,
            String pwd, String dir, String src) {
        String SFTPHOST = host;
        int SFTPPORT = post;
        String SFTPUSER = user;
        String SFTPPASS = pwd;
        String SFTPWORKINGDIR = dir;
        String FILETOTRANSFER = src;
        Session session = null;
        Channel channel = null;
        ChannelSftp channelSftp = null;
        try {
            JSch jsch = new JSch();
            session = jsch.getSession(SFTPUSER, SFTPHOST, SFTPPORT);
            session.setPassword(SFTPPASS);
            java.util.Properties config = new java.util.Properties();
            config.put("StrictHostKeyChecking", "no");
            config.put("kex", "diffie-hellman-group1-sha1"); // 适配新版本ssh需添加对应的加密算法
            session.setConfig(config);
            session.connect();
            channel = session.openChannel("sftp");
            channel.connect();
            channelSftp = (ChannelSftp) channel;
            channelSftp.cd(SFTPWORKINGDIR);
            File f = new File(FILETOTRANSFER);
            channelSftp.put(new FileInputStream(f), f.getName());
            channelSftp.disconnect();
            channel.disconnect();
            session.disconnect();
        } catch (Exception ex) {
            ex.printStackTrace();
            return false;
        }

        return true;
    }
    
    public static void main(String[] args) {
        boolean result = uploadFile("192.168.182.128", 22, "root", "123456", "/opt/","E:\\file\\1.doc");
        System.out.println("上传结果：" + result);
    }
}

2.scp文件上传（需要的lib文件地址：ganymed-ssh2-build210.jar ）

import java.io.IOException;

import ch.ethz.ssh2.Connection;
import ch.ethz.ssh2.SCPClient;

public class ScpUtils {

     static synchronized public ScpUtils getInstance(String ip, int port, String username, String passward) {
            if (instance == null) {
                instance = new ScpUtils(ip, port, username, passward);
            }
            return instance;
        }

            this.username = username;
            this.password = passward;
        }

        public void getFile(String remoteFile, String localTargetDirectory) {
            Connection conn = new Connection(ip, port);
            try {
                conn.connect();
                boolean isAuthenticated = conn.authenticateWithPassword(username, password);
                if (!isAuthenticated) {

                }
                SCPClient client = new SCPClient(conn);
                client.get(remoteFile, localTargetDirectory);
            } catch (IOException ex) {
                ex.printStackTrace();
            }finally{
                conn.close();
            }
        }

        }

            Connection conn = new Connection(ip, port);
            try {
                conn.connect();
                boolean isAuthenticated = conn.authenticateWithPassword(username, password);
                if (!isAuthenticated) {
                    System.err.println("authentication failed");
                }
                SCPClient client = new SCPClient(conn);
                if ((mode == null) || (mode.length() == 0)) {
                    mode = "0600";
                }
                if (remoteFileName == null) {
                    client.put(localFile, remoteTargetDirectory);
                } else {
                    client.put(localFile, remoteFileName, remoteTargetDirectory, mode);
                }
            } catch (IOException ex) {
                ex.printStackTrace();
            }finally{
                conn.close();
            }
        }

        public static void main(String[] args) {
            ScpUtils scpClient = getInstance("192.168.182.128", 22, "root", "123456");
            scpClient.putFile("E:\\file\\1.doc","/opt");
