Java Socket简单的客服端及其服务器端

最近给别人写了个服务器读文件，然后传到客服端，客服端收到消息再写到客服机器中的一个socket程序，socket传输协议用的是TCP，读文件和写文件的路径都用properties配置文件来配置。

客服端文件源代码如下：

package javaSocket;

import java.io.BufferedInputStream;
import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.InetAddress;
import java.net.Socket;
import java.util.Properties;

public class SocketClient{
    private Socket skClient;
    public SocketClient(){
     
    }
    public void clientCreate(){
     InputStream in;   
     try {
      in = new BufferedInputStream(new FileInputStream("d:\test.properties"));
   Properties p = new Properties();
   p.load(in);
   String path = p.getProperty("path1");
      FileOutputStream fos = new FileOutputStream(path);
   skClient = new Socket(InetAddress.getLocalHost(),8888);
   System.out.println("向服务器发出链接请求！");      
      copyStream(skClient.getInputStream(),fos);   
   skClient.close();
   fos.close();
  }catch (Exception e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
    }

    public void copyStream(InputStream is, OutputStream os) throws IOException {
        String line;
        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
        PrintWriter writer = new PrintWriter(new OutputStreamWriter(os));
        line = reader.readLine();
        while (line != null) {
            writer.println(line);
            line = reader.readLine();
        }
        writer.flush(); 
    }
 public static void main(String[] args) {
  // TODO Auto-generated method stub
        new SocketClient().clientCreate();
 }

}

服务器端的源代码如下：

package javaSocket;

import java.io.BufferedInputStream;
import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.Properties;

public class SocketServer extends Thread{
    private Socket skServer;
    public SocketServer(Socket s){
     this.skServer = s;
    }
    public void run(){
     InputStream in;
     try {
      in = new BufferedInputStream(new FileInputStream("d:\test.properties"));
   Properties p = new Properties();
   p.load(in);
   String path = p.getProperty("path2");
      FileInputStream fis = new FileInputStream(path);
      copyStream(fis,skServer.getOutputStream());
   skServer.close();
   fis.close();
   
  } catch (Exception e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
     
    }
   
    public void copyStream(InputStream is, OutputStream os) throws IOException {
        String line;
        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
        PrintWriter writer = new PrintWriter(new OutputStreamWriter(os));
        line = reader.readLine();
        while (line != null) {
            writer.println(line);
            line = reader.readLine();
        }
        writer.flush(); 
    }
 public static void main(String[] args) throws IOException {
  // TODO Auto-generated method stub
        ServerSocket server = new ServerSocket(8888);
        System.out.println("服务器已经启动，已处于监听状态......");
        while(true){
         SocketServer ss = new SocketServer(server.accept());
         System.out.println("成功响应客服端！");
         ss.start();
        }
 }

}

配置属性文件test.properties:

path1=D:\123.txt

path2=D:\456.txt

因为写的时间比较急，所以很多地方需要修改。基本功能已经实现了。有兴趣就可以再修改完善。
