服务端:

package com.huan.yu1;

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

public class ServerSokcetDemo1 implements Runnable {

	private Socket s;

	public ServerSokcetDemo1(Socket s) {
		super();
		this.s = s;
	}

	/**
	 * 定义一个线程
	 */

	@Override
	public void run() {
		// 读取客户端的数据进行上传
		int count = 1;
		String ip = s.getInetAddress().getHostAddress();
		System.err.println(ip + "---connect");
		// 读取客户端发过来得数据
		try {
			InputStream is = s.getInputStream();
			// 定义目的地
			byte[] b = new byte[1024 * 4];
			File file = new File("F://ppp");
			if (!file.exists()) {
				file.mkdir();
			}
			// 重新定义上传文件的路径和名称
			File child = new File(file, ip + "00" + count + ".jpg");
			// 如果存在就重新创建
			while (child.exists()) {
				child = new File(file, ip + "00" + count + ".jpg");
			}
			FileOutputStream fos = new FileOutputStream(child);
			int len = 0;
			while ((len = is.read(b)) != -1) {
				fos.write(b);
			}

			OutputStream out = s.getOutputStream();

			out.write("上传成功".getBytes());
			fos.close();
			s.close();
			

		} catch (IOException e) {
			e.printStackTrace();
		}

	}

	
	/**
	 * 客户端上传数据
	 * 
	 * @throws IOException
	 */
	@SuppressWarnings("resource")
	public static void main(String[] args) throws IOException {
		ServerSocket ss = new ServerSocket(10666);
		while (true) {
			Socket s = ss.accept();
			new Thread(new ServerSokcetDemo1(s)).start();;

		}

	}

}

  

客户端:

package com.huan.yu1;

import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.Socket;
import java.net.UnknownHostException;

public class ClientSocket {

	/**
	 * 客户端
	 * 
	 * @throws IOException
	 * @throws UnknownHostException
	 */
	@SuppressWarnings("resource")
	public static void main(String[] args) throws UnknownHostException, IOException {
		// 请求服务,并且要将数据上传上去
		//本地ip
		Socket s = new Socket("192.168.86.1", 10666);
		FileInputStream fis = new FileInputStream("F://picture//1920.png");
		OutputStream os = s.getOutputStream();
		byte[] b = new byte[1024 * 4];

		int len = 0;
		while ((len = fis.read(b)) != -1) {
			os.write(b);
		}
		// 告诉服务器读取完毕
		s.shutdownOutput();
		// 读取服务器的数据
		InputStream is = s.getInputStream();
		byte[] b1 = new byte[1024 ];
		int len1=is.read(b1);
		String str=new String(b1,0,len1);
		System.err.println(str);
		
		fis.close();
		s.close();
		is.close();
		
		
	}

}
