1. 在实际的应用重，通常是通过程序来进行文件的上传。

2. 实现java上传文件到ftp服务器中

新建maven项目

添加依赖

commons-net

commons-net

3.3

3.实例代码：

package com.test.fto.demo;

/**

* ftp链接常量

*

*/

public class Ftp {

private String ipAddr;//ip地址

private Integer port;//端口号

private String userName;//用户名

private String pwd;//密码

private String path;//aaa路径

public String getIpAddr() {

return ipAddr;

}

public void setIpAddr(String ipAddr) {

this.ipAddr = ipAddr;

}

public Integer getPort() {

return port;

}

public void setPort(Integer port) {

this.port = port;

}

public String getUserName() {

return userName;

}

public void setUserName(String userName) {

this.userName = userName;

}

public String getPwd() {

return pwd;

}

public void setPwd(String pwd) {

this.pwd = pwd;

}

public String getPath() {

return path;

}

public void setPath(String path) {

this.path = path;

}

}
