android 基于apache ftp server

转自：http://blog.csdn.net/yudajun/article/details/8803356

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 en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
                    NetworkInterface intf = en.nextElement();
                    for (Enumeration 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：

"android.permission.WRITE_EXTERNAL_STORAGE" >

    "android.permission.INTERNET" >

    "android.permission.ACCESS_WIFI_STATE" >

    "android.permission.READ_PHONE_STATE" >

    "android.permission.WAKE_LOCK" >

    "android.permission.CHANGE_WIFI_STATE" >

ok,这样简单的就完成了android端ftp server 服务器功能
