获取远程文件2-socket循环式服务器[1]

关于获取远程文件的程序1：http://blog.csdn.net/notruiyi/archive/2005/10/22/513573.aspx

使用socket获取远程文件，要求本地和远程主机都打开端口，所以一般程序都会给出服务器端和客户端

1服务器端

--------------------------------------------------------------------------------------------------------------------------

import java.io.*;

import java.net.*;

public class FileServer{

    private int port = 3000;

    //接收连接

    public void acceptConnections(){

        try{

            ServerSocket server = new SocketServer(port);

            Socket incomingSocket  = null;

            while(true){

                 incomingSocket = server.accept();

                 handleConnections(incomingSocket);

            }

        }catch(BindException e){

            System.out.println("BindException occured.");

        }catch(IOException e){

            System.out.println("ServerSocket establish error.");

        }       

    }

    //处理连接

    public void handleConnecitons(Socket socket){

        try{

            BufferedReader inputReader = new BufferedReader(new InputStreamReader(socket.getInputStream()));

            BufferedReader outputReader = new BufferReader(new OutputStreamReader(socket.getOutputStream()));

            //获取要读取的文件名

            FileReader fileReader = new FileReader(new File(inputReader.readLine()));

            BufferedReader bufferedFileReader = new BufferReader(fileReader);

            PrintWriter printWriter = new PrintWriter(socket.getOutputStream());

            String line = null;

             While((line =  bufferFileReader.readLine())!=null)

                printWriter.println(line);

              fileReader.close();

              printWriter.close();

             outputReader.close();

        }catch(Exception e){

            System.out.println("Exception occured when handiling a client connection.");

        }

    }

}

2.客户端

-----------------------------------------------------------------------------------------------------------------

import java.io.*;

import java.net.*;

public class RemoteFileClient{

    private String hostIP;

    private int hostPort;

    private BufferedReader socketReader;

    private PrintWriter socketWriter;

    public RemoteFileClient(String hostIP,int port ){

        this.hostIP = hostIP;

        this.port = port;

    }

    //启动连接

    public  void setupConnection(){

        try{

            Socket client = new Socket(hostip,port);

           socketReader = new BufferReader(new InputStreamReader(client.getInputStream()));
