Ftp4j还是比较好用的,而且支持各种代理。
当需要通过命令行,通过代理,上传一个目录到远端服务器,同时可以加入调度任务,这种情况下,自己写java就比较适用。
filezilla图形化的客户端,支持代理、支持目录上传,但是不支持调度;
winscp命令行支持上传目录,但不支持代理;
curl支持代理,但不支持上传目录;
其它ftp命令行更是弱鸡。
所以自己动手java,丰衣足食。话不多说,以下代码,在commons-lang-2.6.jar,ftp4j-1.7.2.jar 测试通过。http://www.sauronsoftware.it/projects/ftp4j/download.php
