前言

最近考虑写一个类似 Multicraft 的网站应用程序，其中的FTP的实现让我一直在考虑实现手段，经过自己的查阅资料和测试特此写下该文章！

开发环境

JDK 1.8

FTP-Core依赖

slf4j-nop 依赖(可选 避免日志打印)

代码示例

FTPClient.java

package cn.marinda.rcontest.ftp;

import org.apache.ftpserver.FtpServer;
import org.apache.ftpserver.FtpServerFactory;
import org.apache.ftpserver.ftplet.Authority;
import org.apache.ftpserver.listener.ListenerFactory;
import org.apache.ftpserver.usermanager.PropertiesUserManagerFactory;
import org.apache.ftpserver.usermanager.impl.BaseUser;
import org.apache.ftpserver.usermanager.impl.WritePermission;

import java.io.File;
import java.util.ArrayList;
import java.util.List;

/**
 * @author Marinda
 * @date 2023/4/8 14:06
 * @description FTP连接
 */
public class FtpClient {

    private String userName;
    private String passWord;
    private int port;
    private String dir;
    private String host;
    List<Authority> authorityList = new ArrayList<>();
    private FtpServerFactory ftpServerFactory = new FtpServerFactory();

    public FtpClient(String userName,String passWord,String host,int port,String dir){
        this.userName = userName;
        this.passWord = passWord;
        this.port = port;
        this.dir = dir;
        this.host = host;
        init();
    }

    public FtpClient(){

    }

    private void init(){
        authorityList.add(new WritePermission());
    }


    /*
     * @author Marinda
     * @date 2023/4/8 14:08
     * @description  开启服务
     */
    public void start(){
        try {
            BaseUser baseUser = new BaseUser();
            baseUser.setName(userName);
            baseUser.setHomeDirectory(dir);
            baseUser.setPassword(passWord);
            baseUser.setAuthorities(authorityList);
            ListenerFactory listenerFactory = new ListenerFactory();
            listenerFactory.setPort(port);
            listenerFactory.setServerAddress(host);
            ftpServerFactory.addListener("default", listenerFactory.createListener());
            ftpServerFactory.getUserManager().save(baseUser);
            FtpServer ftpServer = ftpServerFactory.createServer();
            ftpServer.start();
            System.out.println("开启FTP服务");
        }catch (Exception e){
            e.printStackTrace();
        }
    }
}

main.java

        FtpClient ftpClient = new FtpClient("Marinda","root","127.0.0.1",21,"D://");

        ftpClient.start();

温馨提示

如果不需要日志仅仅想我一样搭建一个基础FTP服务的话就可以按需导入slf4j-nop 依赖。

如果有需要可以选择logback / log4这类自行配置，不过这样必须定义日志的实现
