1.依賴的jar文件 jsch-0.1.53.jar
2.登錄方式有密碼登錄,和密匙登錄
代碼:
主函數:
import java.util.Properties; import com.cloudpower.util.Login; import com.util.LoadProperties; public class Ftp { public static void main(String[] args) { Properties properties = LoadProperties.getProperties(); Login.login(properties); } }
登陸頁面的代碼:
package com.cloudpower.util; import java.io.Console; import java.util.Properties; import com.jcraft.jsch.JSch; import com.jcraft.jsch.Session; public class Login { public static void login(Properties properties) { String ip = properties.getProperty("ip"); String user = properties.getProperty("user"); String pwd = properties.getProperty("pwd"); String port = properties.getProperty("port"); String privateKeyPath = properties.getProperty("privateKeyPath"); String passphrase = properties.getProperty("passphrase"); String sourcePath = properties.getProperty("sourcePath"); String destinationPath = properties.getProperty("destinationPath"); if (ip != null && !ip.equals("") && user != null && !user.equals("") && port != null && !port.equals("") && sourcePath != null && !sourcePath.equals("") && destinationPath != null && !destinationPath.equals("")) { if (privateKeyPath != null && !privateKeyPath.equals("")) { sshSftp2(ip, user, Integer.parseInt(port), privateKeyPath, passphrase, sourcePath, destinationPath); } else if (pwd != null && !pwd.equals("")) { sshSftp(ip, user, pwd, Integer.parseInt(port), sourcePath, destinationPath); } else { Console console = System.console(); System.out.print("Enter password:"); char[] readPassword = console.readPassword(); sshSftp(ip, user, new String(readPassword), Integer.parseInt(port), sourcePath, destinationPath); } } else { System.out.println("請先設置配置文件"); } } /** * 密碼方式登錄 * * @param ip * @param user * @param psw * @param port * @param sPath * @param dPath */ public static void sshSftp(String ip, String user, String psw, int port, String sPath, String dPath) { System.out.println("password login"); Session session = null; JSch jsch = new JSch(); try { if (port <= 0) { // 連接服務器,采用默認端口 session = jsch.getSession(user, ip); } else { // 采用指定的端口連接服務器 session = jsch.getSession(user, ip, port); } // 如果服務器連接不上,則拋出異常 if (session == null) { throw new Exception("session is null"); } // 設置登陸主機的密碼 session.setPassword(psw);// 設置密碼 // 設置第一次登陸的時候提示,可選值:(ask | yes | no) session.setConfig("StrictHostKeyChecking", "no"); // 設置登陸超時時間 session.connect(300000); UpLoadFile.upLoadFile(session, sPath, dPath); } catch (Exception e) { e.printStackTrace(); } System.out.println("success"); } /** * 密匙方式登錄 * * @param ip * @param user * @param port * @param privateKey * @param passphrase * @param sPath * @param dPath */ public static void sshSftp2(String ip, String user, int port, String privateKey, String passphrase, String sPath, String dPath) { System.out.println("privateKey login"); Session session = null; JSch jsch = new JSch(); try { // 設置密鑰和密碼 // 支持密鑰的方式登陸,只需在jsch.getSession之前設置一下密鑰的相關信息就可以了 if (privateKey != null && !"".equals(privateKey)) { if (passphrase != null && "".equals(passphrase)) { // 設置帶口令的密鑰 jsch.addIdentity(privateKey, passphrase); } else { // 設置不帶口令的密鑰 jsch.addIdentity(privateKey); } } if (port <= 0) { // 連接服務器,采用默認端口 session = jsch.getSession(user, ip); } else { // 采用指定的端口連接服務器 session = jsch.getSession(user, ip, port); } // 如果服務器連接不上,則拋出異常 if (session == null) { throw new Exception("session is null"); } // 設置第一次登陸的時候提示,可選值:(ask | yes | no) session.setConfig("StrictHostKeyChecking", "no"); // 設置登陸超時時間 session.connect(300000); UpLoadFile.upLoadFile(session, sPath, dPath); System.out.println("success"); } catch (Exception e) { e.printStackTrace(); } } }
文件上傳的代碼:
package com.cloudpower.util; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import java.util.Scanner; import com.jcraft.jsch.Channel; import com.jcraft.jsch.ChannelSftp; import com.jcraft.jsch.Session; import com.jcraft.jsch.SftpException; public class UpLoadFile { public static void upLoadFile(Session session, String sPath, String dPath) { Channel channel = null; try { channel = (Channel) session.openChannel("sftp"); channel.connect(10000000); ChannelSftp sftp = (ChannelSftp) channel; try { sftp.cd(dPath); Scanner scanner = new Scanner(System.in); System.out.println(dPath + ":此目錄已存在,文件可能會被覆蓋!是否繼續y/n?"); String next = scanner.next(); if (!next.toLowerCase().equals("y")) { return; } } catch (SftpException e) { sftp.mkdir(dPath); sftp.cd(dPath); } File file = new File(sPath); copyFile(sftp, file, sftp.pwd()); } catch (Exception e) { e.printStackTrace(); } finally { session.disconnect(); channel.disconnect(); } } public static void copyFile(ChannelSftp sftp, File file, String pwd) { if (file.isDirectory()) { File[] list = file.listFiles(); try { try { String fileName = file.getName(); sftp.cd(pwd); System.out.println("正在創建目錄:" + sftp.pwd() + "/" + fileName); sftp.mkdir(fileName); System.out.println("目錄創建成功:" + sftp.pwd() + "/" + fileName); } catch (Exception e) { // TODO: handle exception } pwd = pwd + "/" + file.getName(); try { sftp.cd(file.getName()); } catch (SftpException e) { // TODO: handle exception e.printStackTrace(); } } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } for (int i = 0; i < list.length; i++) { copyFile(sftp, list[i], pwd); } } else { try { sftp.cd(pwd); } catch (SftpException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } System.out.println("正在復制文件:" + file.getAbsolutePath()); InputStream instream = null; OutputStream outstream = null; try { outstream = sftp.put(file.getName()); instream = new FileInputStream(file); byte b[] = new byte[1024]; int n; try { while ((n = instream.read(b)) != -1) { outstream.write(b, 0, n); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } catch (SftpException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } finally { try { outstream.flush(); outstream.close(); instream.close(); } catch (Exception e2) { // TODO: handle exception e2.printStackTrace(); } } } } }
讀取配置文件的代碼:
package com.util; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.InputStream; import java.util.Properties; public class LoadProperties { public static Properties getProperties() { File file = new File(Class.class.getClass().getResource("/").getPath() + "properties.properties"); InputStream inputStream = null; try { inputStream = new FileInputStream(file); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } Properties properties = new Properties(); try { properties.load(inputStream); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return properties; } }
代碼目錄結構:
測試運行時配置文件放在項目的bin目錄下(打包成可運行jar文件的時候要刪除,打包完成后將配置文件和jar包放在同級目錄下即可):
properties.properties
ip= user= pwd= port=22 privateKeyPath= passphrase= sourcePath= destinationPath=/home/dbbs/f
打包可運行jar文件:
Export->java->Runnabe JAR file
完成后
在控制臺運行java -jar 導出jar包的名字.jar 即可
