packagecom.itv.launcher.util; publicInterfaceConstants {// 路径分隔符 publicStaticString file_separator = System.getProperty ("file.separator");}3. FTP 链接的配置 Propriétés 文件 ， 包括用户名密码一些信息
#Ftp 的 ip 地址 ftp_url = 127.0.0.1 # ftp 端口号 ftp_port = 1234 # 用户名 ftp_user = yanzhou # 密码 ftp_password = abcdefg12345 # ftp 账号目录 ftp_remote_filepath =
以上这篇 JDK1.7 以上 Javaftp 上传删除文件的实现方法就是小编分享给大家的全部内容了 ， 希望能给大家一个参考 ， 也希望大家多多支持武林网。
