#表示admin的密码是123456 以下都是admin的参数设置，可以多个
ftpserver.user.admin.userpassword=123456
ftpserver.user.admin.homedirectory=/home/data/ftp
ftpserver.user.admin.enableflag=true
ftpserver.user.admin.writepermission=true

ftpserver.user.admin.maxloginperip=0
ftpserver.user.admin.idletime=0
ftpserver.user.admin.uploadrate=0
ftpserver.user.admin.downloadrate=0

 

 

yml配置文件加入

ftp:
  port: 21 #ftp连接端口
  passivePorts: 20  #被动连接数据传输端口
  passiveExternalAddress: 127.0.0.1 #部署的服务器ip地址

 

 

然后启动SpringBoot服务

工具连接

 

 

 

 账号密码就是配置文件里面的密码
