客户端：

package cn.itcast.uploadpicture.demo;

import java.io.BufferedInputStream;

import java.io.FileInputStream;

import java.io.IOException;

import java.io.InputStream;

import java.io.PrintStream;

import java.net.Socket;

import java.net.UnknownHostException;

public class UploadpicClient {

public static void main(String[] args) throws UnknownHostException, IOException {

// 1、建立客户端的Socket服务

Socket s=new Socket("192.168.1.216",10012);

// 2、获取图片资源

BufferedInputStream burin=

new BufferedInputStream(new FileInputStream("F:\\CloudMusic\\罗大佑,黄霑,徐克 - 沧海一声笑.mp3"));

// 3、获取socket输出流

PrintStream pso=new PrintStream(s.getOutputStream(),true);

// 4、将数据写入到输出流

byte[]buff=new byte[1024];

int len=-1;

while((len=burin.read(buff))!=-1) {

pso.write(buff, 0, len);

}

s.shutdownOutput();

// 5、获取服务端的返回的数据

InputStream is=s.getInputStream();

byte[]buffin=new byte[1024];

int lenth=is.read(buffin);

String str=new String(buffin,0,lenth);

System.out.println(str);

// 6、关闭流

s.close();

burin.close();

}

}

服务端：

package cn.itcast.uploadpicture.demo;

import java.io.BufferedInputStream;

import java.io.File;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.PrintStream;

import java.net.ServerSocket;

import java.net.Socket;

public class UploadpicServer {

public static void main(String[] args) throws IOException {

ServerSocket ss=new ServerSocket(10012);

Socket s=ss.accept();

System.out.println(s.getInetAddress().getHostAddress()+"connnected.......");

BufferedInputStream burin=new BufferedInputStream(s.getInputStream());

File file=new File("serve.mp3");

if(!file.exists())

file.mkdirs();

PrintStream ps=new PrintStream(new FileOutputStream(file),true);

byte[]buff=new byte[1024];

int len=-1;

while((len=burin.read(buff))!=-1) {

ps.write(buff, 0, len);

}

PrintStream psout=new PrintStream(s.getOutputStream(),true);

psout.println("上传成功");

ss.close();

s.close();

ps.close();

}

}
