Java TCP套接字编程（二）文件传输

客户端：

package com.zzz.net;

import java.io.*;
import java.net.InetAddress;
import java.net.Socket;

public class TcpClientDemo02 {
    public static void main(String[] args) throws Exception {
        Socket socket = new Socket(InetAddress.getByName("127.0.0.1"), 8080);   //创建一个socket
        OutputStream os = socket.getOutputStream();                       //创建一个输出流
        FileInputStream fis = new FileInputStream("picture1.jpg");    //读取文件
        byte[] buffer = new byte[1024];     //写出文件
        int len;
        while ((len=fis.read(buffer))!=-1){
            os.write(buffer,0,len);
        }

        //通知服务器，传输完毕
        socket.shutdownOutput();

        //确定服务器接收完毕，才能够断开连接
        InputStream is = socket.getInputStream();
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        byte[] buffer2 = new byte[1024];
        int len2;
        while((len2=is.read(buffer2))!=-1){
            baos.write(buffer2,0,len2);
        }
        System.out.println(baos.toString());


        //关闭资源
        baos.close();
        is.close();
        fis.close();
        os.close();
        socket.close();

    }
}

服务器：

package com.zzz.net;

import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class TcpServerDemo02 {
    public static void main(String[] args) throws Exception {
        ServerSocket serverSocket = new ServerSocket(8080); //创建服务
        Socket socket = serverSocket.accept();  //监听连接
        InputStream is = socket.getInputStream();   //获取输入流
        FileOutputStream fos = new FileOutputStream("receive1.jpg"); //文件输出
        byte[] buffer = new byte[1024];
        int len;
        while((len=is.read(buffer))!=-1){
            fos.write(buffer,0,len);
        }
        //通知客户端我接收完毕了
        OutputStream os = socket.getOutputStream();
        os.write("我接收完毕了，你可以断开了".getBytes());


        //关闭资源
        os.close();
        fos.close();
        is.close();
        socket.close();
        serverSocket.close();
    }
}
