android 基于apache ftp server

最近研究了一下在android端实现ftp server 功能，在网上搜了几个，没有能用的基本是各种抄袭，还是自己研究吧

首先到 apache官网下载ftp server 相关jar和配置文件，最新的是Apache FtpServer 1.0.6 Release版本

看一下效果图：

由于是apache已经将ftp server相关的实现封装的很好了，所以实现起来就简单多了

导入路径\apache-ftpserver-1.0.6\common\lib下相关jar包

主要的jar包文件

实现代码：

package com.orgcent.ftp;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.Enumeration;

import org.apache.ftpserver.FtpServer;
import org.apache.ftpserver.FtpServerFactory;
import org.apache.ftpserver.ftplet.FtpException;
import org.apache.ftpserver.listener.ListenerFactory;
import org.apache.ftpserver.ssl.SslConfigurationFactory;
import org.apache.ftpserver.usermanager.PropertiesUserManagerFactory;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.os.Environment;
import android.util.Log;
import android.widget.TextView;

public class FtpServerActivity extends Activity {

	
	private FtpServer mFtpServer;
	private String ftpConfigDir= Environment.getExternalStorageDirectory().getAbsolutePath()+"/ftpConfig/";

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		
		TextView tv=(TextView)findViewById(R.id.tvText);
		String info="请通过浏览器或者我的电脑访问以下地址\n"+"ftp://"+getLocalIpAddress()+":2221\n";
		tv.setText(info);
		
		File f=new File(ftpConfigDir);
		if(!f.exists())
			f.mkdir();
		copyResourceFile(R.raw.users, ftpConfigDir+"users.properties");
		Config1();
	}

	 public String getLocalIpAddress() {
	    	String strIP=null;
	        try {
	            for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
	                NetworkInterface intf = en.nextElement();
	                for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
	                    InetAddress inetAddress = enumIpAddr.nextElement();
	                    if (!inetAddress.isLoopbackAddress()) {
	                    	strIP= inetAddress.getHostAddress().toString();
	                    }
	                }
	            }
	        } catch (SocketException ex) {
	            Log.e("msg", ex.toString());
	        }
	        return strIP;
	    }
	 
	private void copyResourceFile(int rid, String targetFile){
        InputStream fin = ((Context)this).getResources().openRawResource(rid);
        FileOutputStream fos=null;
        int length;
		try {
			fos = new FileOutputStream(targetFile);
			byte[] buffer = new byte[1024]; 
	        while( (length = fin.read(buffer)) != -1){
	            fos.write(buffer,0,length);
	        }
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		} finally{
			if(fin!=null){
				try {
					fin.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
			 if(fos!=null){
				 try {
					fos.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			 }
		}
    }
	
	void Config1(){
//		Now, let's configure the port on which the default listener waits for connections.

			FtpServerFactory serverFactory = new FtpServerFactory();
			        
			ListenerFactory factory = new ListenerFactory();
			        
			PropertiesUserManagerFactory userManagerFactory = new PropertiesUserManagerFactory();
			
			String[] str ={"mkdir", ftpConfigDir};
	        try { 
	            Process ps = Runtime.getRuntime().exec(str);
	            try {
	                ps.waitFor();
	            } catch (InterruptedException e) {
	                e.printStackTrace();
	            } 
	        }catch (IOException e) {
	            e.printStackTrace();
	        }
	        
			String filename=ftpConfigDir+"users.properties";//"/sdcard/users.properties";
			File files=new File(filename);
			
			userManagerFactory.setFile(files);
	        serverFactory.setUserManager(userManagerFactory.createUserManager());
			// set the port of the listener
			factory.setPort(2221);

			// replace the default listener
			serverFactory.addListener("default", factory.createListener());
			                
			// start the server
			FtpServer server = serverFactory.createServer(); 
			this.mFtpServer = server;       
			try {
				server.start();
			} catch (FtpException e) {
				e.printStackTrace();
			}
	}
	
	void Config2(){
//		Now, let's make it possible for a client to use FTPS (FTP over SSL) for the default listener.


		FtpServerFactory serverFactory = new FtpServerFactory();
		        
		ListenerFactory factory = new ListenerFactory();
		        
		// set the port of the listener
		factory.setPort(2221);

		// define SSL configuration
		SslConfigurationFactory ssl = new SslConfigurationFactory();
		ssl.setKeystoreFile(new File(ftpConfigDir+"ftpserver.jks"));
		ssl.setKeystorePassword("password");

		// set the SSL configuration for the listener
		factory.setSslConfiguration(ssl.createSslConfiguration());
		factory.setImplicitSsl(true);

		// replace the default listener
		serverFactory.addListener("default", factory.createListener());
		        
		PropertiesUserManagerFactory userManagerFactory = new PropertiesUserManagerFactory();
		userManagerFactory.setFile(new File(ftpConfigDir+"users.properties"));
		        
		serverFactory.setUserManager(userManagerFactory.createUserManager());
		        
		// start the server
		FtpServer server = serverFactory.createServer(); 
		this.mFtpServer = server;  
		try {
			server.start();
		} catch (FtpException e) {
			e.printStackTrace();
		}
	}
	
	@Override
	protected void onDestroy() {
		super.onDestroy();
		
		if(null != mFtpServer) {
			mFtpServer.stop();
			mFtpServer = null;
		}
	}
	
}

最重要一步，配置文件修改

配置文件所在目录：apache-ftpserver-1.0.6\res\conf

这里我们主要使用users.properties配置文件，修改内容如下

# Password is "admin"
ftpserver.user.admin.userpassword=21232F297A57A5A743894A0E4A801FC3

ftpserver.user.admin.homedirectory=/mnt/sdcard
ftpserver.user.admin.enableflag=true
ftpserver.user.admin.writepermission=true
ftpserver.user.admin.maxloginnumber=0
ftpserver.user.admin.maxloginperip=0
ftpserver.user.admin.idletime=0
ftpserver.user.admin.uploadrate=0
ftpserver.user.admin.downloadrate=0

ftpserver.user.anonymous.userpassword=admin
ftpserver.user.anonymous.homedirectory=/mnt/sdcard
ftpserver.user.anonymous.enableflag=true
ftpserver.user.anonymous.writepermission=true
ftpserver.user.anonymous.maxloginnumber=20
ftpserver.user.anonymous.maxloginperip=2
ftpserver.user.anonymous.idletime=300
ftpserver.user.anonymous.uploadrate=4800
ftpserver.user.anonymous.downloadrate=4800

最后别忘了相关权限：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" >
    </uses-permission>
    <uses-permission android:name="android.permission.INTERNET" >
    </uses-permission>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" >
    </uses-permission>
    <uses-permission android:name="android.permission.READ_PHONE_STATE" >
    </uses-permission>
    <uses-permission android:name="android.permission.WAKE_LOCK" >
    </uses-permission>
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" >
    </uses-permission>

ok,这样简单的就完成了android端ftp server 服务器功能
