java代码实现使用 SFTP 文件上传linux服务器

1、maven依赖

<dependency>
    <groupId>com.jcraftgroupId>
    <artifactId>jschartifactId>
    <version>0.1.55version>
dependency>
<dependency>
    <groupId>commons-netgroupId>
    <artifactId>commons-netartifactId>
    <version>3.8.0version>
dependency>

2、工具类

public class SFTPUtil {
	/**
	  * 向FTP服务器上传文件
	  *
	  * @param host     FTP服务器ip
	  * @param port     FTP服务器端口
	  * @param username FTP登录账号
	  * @param password FTP登录密码
	  * @param dst      FTP服务器目录
	  * @param filename 文件名
	  * @param input    输入流
	  */
	 public static void uploadFileSFTP(String host, int port, String username, String password, String dst,String filename, InputStream inputStream){
	     Session session = null;
	     Channel channel = null;
	     ChannelSftp channelSftp = null;
	     try {
	         JSch jsch = new JSch();
	         session = jsch.getSession(username, host, port);
	         session.setPassword(password);
	         java.util.Properties config = new java.util.Properties();
	         config.put("StrictHostKeyChecking", "no");
	         session.setConfig(config);
	         session.connect();
	         channel = session.openChannel("sftp");
	         channel.connect();
	         channelSftp = (ChannelSftp) channel;
	         channelSftp.put(inputStream, dst+filename, ChannelSftp.OVERWRITE);
	         System.out.println("File uploaded successfully");
	     } catch (Exception e) {
	         e.printStackTrace();
	     } finally {
	         channelSftp.exit();
	         channel.disconnect();
	         session.disconnect();
	     }
	 }
}

3、代码调用

 SFTPUtil.uploadFileSFTP("192.168.31.111",22,"root", "root", "/home/", "aaa.jpg", inputStream);
