本文档介绍了如何使用Java实现一个FTP服务器，包括设置目录选择、创建匿名用户并赋予写权限。重点在于Apache FtpServer的配置和用户管理。

package a;

import java.awt.BorderLayout;
import java.util.ArrayList;

import javax.swing.JFileChooser;
import javax.swing.JFrame;
import javax.swing.JLabel;

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.impl.BaseUser;
import org.apache.ftpserver.usermanager.impl.WritePermission;

public class Main extends JFrame {
   public Main() throws Exception {
       this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
       String dir = "c:\\";
       JFileChooser jfc = new JFileChooser(dir);
       jfc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
       if (jfc.showOpenDialog(this) == 0) {
           dir = jfc.getSelectedFile().getAbsolutePath();
       }
       JLabel jl = new JLabel(dir);
       this.add(jl, BorderLayout.NORTH);
       ArrayList<Authority> la = new ArrayList<Authority>();
       WritePermission wp = new WritePermission();
       BaseUser bu = new BaseUser();
       ListenerFactory lf = new ListenerFactory();
       FtpServerFactory fsf = new FtpServerFactory();

       la.add(wp);
       bu.setName("anonymous");
       bu.setPassword(null);
       // bu.setHomeDirectory(dir);
       bu.setAuthorities(la);
       lf.setPort(21);
       fsf.addListener("default", lf.createListener());
       fsf.getUserManager().save(bu);
       FtpServer fs = fsf.createServer();
       fs.start();

}

   public static void main(String[] args) throws Exception {
       Main m = new Main();
       m.setVisible(true);
   }

}
