使用Apache Commons Net包实现javaFTP来上传目录

使用Apache Commons Net包实现javaFTP来上传目录

 

复杂的地方体现在文件夹的上传。

 

在前面层用Apache Commons Net工具包实现了Java FTP单个文件的上传下载功能，这次，实现的是对一个本地目录的上传，实现费了很大劲，虽然实现了 ，但是感觉还是对此封装不是非常满意，改用了其他的FTP客户端工具。将这个半成品放出来供各位研究吧。

 

ftpconfig.properties

username=admin
password=123
ip=192.168.14.117
port=21
