Apache FtpServer 添加用户实现

     Apache FtpServer 用户管理提供两种方式，一种是基于配置文件，一种是数据库。官方网站对Mysql数据库做了测试。

 

    基于配置文件的用户管理，myuser.properties

ftpserver.user.chen.userpassword=123
ftpserver.user.chen.homedirectory=./src/userftp
ftpserver.user.chen.maxloginperip=4
ftpserver.user.chen.maxloginnumber=3
ftpserver.user.chen.downloadrate=0
ftpserver.user.chen.uploadrate=0
ftpserver.user.chen.idletime=0
ftpserver.user.chen.writepermission=true
ftpserver.user.chen.enableflag=true

 

    动态添加用户，通过PropertiesUserManagerFactory创建UserManager然后向配置文件添加用户，代码如下：

 

       public UserManager getUserManager(){
		String userfile = System.getProperty("user.dir")+File.separator+"src"+File.separator+"ftpserver/myuser.properties";
		PropertiesUserManagerFactory propusermanagerfactory = new PropertiesUserManagerFactory();
		File file = new File(userfile);
		UserManager usermanager = null;
		if(file.exists()){
			propusermanagerfactory.setFile(file);
			SaltedPasswordEncryptor salterpassword = new SaltedPasswordEncryptor();
			salterpassword.encrypt("clear");
			propusermanagerfactory.setPasswordEncryptor(salterpassword);
			usermanager = propusermanagerfactory.createUserManager();
		}else{
			System.out.println("用户属性文件不存在");
		}
		return usermanager;
	}


        /**
	 * 添加用户
	 * @param useraccount 用户名
	 * @param password    密码
	 * @param homdir      目录地址
	 * @throws FtpException 
	 */
	public void addUser(String useraccount,String password,String homdir) throws FtpException{
		UserManager usermanager = getUserManager();
		BaseUser user = new BaseUser();
		user.setHomeDirectory(homdir);
		user.setName(useraccount);
		user.setPassword(password);
		usermanager.save(user);//user 必须是实现User接口的实体类
	}
	
	/**
	 * 检测用户是否存在
	 * @param username 用户名
	 * @return
	 * @throws FtpException 
	 */
	public boolean exitUser(String username) throws FtpException{
		UserManager usermanager = getUserManager();
		return usermanager.doesExist(username);
	}
	
	/**
	 * 删除用户
	 * @param username
	 * @throws FtpException 
	 */
	public void deletUser(String username) throws FtpException{
		UserManager usermanager = getUserManager();
		usermanager.delete(username);
	}
        
        //测试调用程序
        public static void main(String args[]){
		FtpServerUserUtil ftpusertil = new FtpServerUserUtil();
		try {
			ftpusertil.addUser("chen2", "123", "./src/userftp");
		} catch (FtpException e) {
			e.printStackTrace();
		}
	}

   BaseUser 是实现了User接口

 

package com.dt.ftp.util;

import java.util.List;

import org.apache.ftpserver.ftplet.Authority;
import org.apache.ftpserver.ftplet.AuthorizationRequest;
import org.apache.ftpserver.ftplet.User;

/**
 * 实现User接口
 * @author Administrator
 *
 */
public class BaseUser implements User{
    private String name;
    private String password;
    private String homeDirectory;
	public void setName(String name) {
		this.name = name;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public void setHomeDirectory(String homeDirectory) {
		this.homeDirectory = homeDirectory;
	}

	public AuthorizationRequest authorize(AuthorizationRequest arg0) {
		
		return null;
	}

	public List getAuthorities() {
		
		return null;
	}

	public List getAuthorities(Class arg0) {
		
		return null;
	}

	public boolean getEnabled() {
		
		return false;
	}

	public String getHomeDirectory() {
		
		return homeDirectory;
	}

	public int getMaxIdleTime() {
		
		return 0;
	}

	public String getName() {
		
		return name;
	}

	public String getPassword() {
		
		return password;
	}
	
}
