Android使用ApacheFtpServer實現Ftp伺服器

為了方便在Android手機和PC電腦之間檔案傳輸和管理，於是想在Android上建立FTP伺服器來實現檔案訪問及管理操作。從網上搜尋到，Apache的FtpServer有java版本，便做了一個移植，發現很方便。
1、匯入Apache FtpServer依賴jar包
commons-net-ftp-2.0.jar
ftpserver-core-1.0.6.jar
log4j-1.2.14.jar
mina-core-2.0.4.jar
slf4j-api-1.5.2.jar
slf4j-log4j12-1.5.2.jar
2、Android啟動FtpServer範例程式碼
package com.orgcent.ftp;

import org.apache.ftpserver.FtpServer;
import org.apache.ftpserver.FtpServerFactory;
import org.apache.ftpserver.ftplet.FtpException;
import org.apache.ftpserver.listener.ListenerFactory;

import android.app.Activity;
import android.os.Bundle;

public class FtpServerActivity extends Activity {

    static { //由於Android系統版本原因，有些對ipv6支援存在bug,相關異常看文章底部介紹
        System.setProperty("java.net.preferIPv6Addresses", "false");
    }
   
    private FtpServer mFtpServer;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
       
//      try {
//          InputStream is = getResources().getAssets().open("log4j.properties");
//          Properties prop = new Properties();
//          prop.load(is);
//         
//          File file = new File(getDir("log", MODE_WORLD_WRITEABLE), "ftp.log");
//          prop.setProperty("log4j.appender.R.File", file.getAbsolutePath());
//          PropertyConfigurator.configure(prop);
//      } catch (IOException e) {
//          e.printStackTrace();
//      }

        startFtpServer();
    }

    private void startFtpServer() {
        FtpServerFactory serverFactory = new FtpServerFactory();

        ListenerFactory factory = new ListenerFactory();

        // set the port of the listener
        int port = 2221;
        factory.setPort(port);

        // 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();
        }

    }
   
    @Override
    protected void onDestroy() {
        super.onDestroy();
       
        if(null != mFtpServer) {
            mFtpServer.stop();
            mFtpServer = null;
        }
    }
}
通過上面配置基本上就實現Android上FtpServer的建立。關於IPV6支援的bug可以查看解決android網路異常java.net.SocketException: Bad address family
