ftp服务器环境
首先要在阿里云ECS上搭建ftp服务器,默认是有vsftpd ,它是 Linux 下的一款小巧轻快、安全易用的 FTP 服务器软件。
用下面命令查看是否安装了vsftpd,阿里云ECS默认是安装好的,如果没有参考网上文章安装。
[root@izuf672oio5mc4fbyj0s0jz ~]# rpm -qa| grep vsftpd
vsftpd-3.0.2-22.el7.x86_64
新建用户ftpuser:
useradd ftpuser -d /home/ftpfile
设置用户密码:
passwd ftpuser
配置springboot项目
多数教程里面使用的标准的ftp maven依赖:
commons-net
commons-net
3.6
但是我使用的是阿里云的ECS上安装的ftp,在进行连接的时候他提示协议不正确,需要使用sftp,所以maven依赖换成了:
com.jcraft
jsch
0.1.49
配置信息

LOG.info("……&&&正在发送 : " + fileName);
if (sftpHelper.connection()) {
sftpHelper.put(xmlFilepath + "/" + fileName, REMOTE_DIR + fileName);
}
i++;
}
}
sftpHelper.close();
