客户端

Cleint.java

public class Client {    public static void main(String[] args) {        try (Socket socket = new Socket("10.0.179.204", 11000)) {            FileInputStream fis = new FileInputStream("src/plant.txt");            InputStream is = socket.getInputStream();            OutputStream os = socket.getOutputStream();            int length;            byte[] bytes = new byte[1024];            while((length = fis.read(bytes)) != -1){                os.write(bytes,0,length);            }            /*            * 禁用此套接字的输出流。对于 TCP 套接字，任何以前写入的数据都将被发送，并且后跟 TCP 的正常连接终止序列。 如果在套接字上调用                      shutdownOutput() 后写入套接字输出流，则该流将抛出 IOException。否则会出现错误。            * */            socket.shutdownOutput();            byte[] bytes1 = new byte[1024];            int num = is.read(bytes1);            System.out.println(new String(bytes1,0,num));            fis.close();            socket.close();        } catch (IOException e) {            e.printStackTrace();        }    }}

客户子线程

UserThread.java

public class UserThread implements Runnable {    private Socket s;    public UserThread(Socket s) {        this.s = s;    }    @Override    public void run() {        try {                OutputStream os = s.getOutputStream();                InputStream is = s.getInputStream();                int count=1;                File f = new File("d:\\test"+"("+count+")"+".txt");//由于是多个不同的客户端向服务端传送文件，所以要考虑文件重名，导致被覆盖。            while (f.exists()) {                f = new File("d:\\test"+"("+ count++ +")"+".txt");            }            FileOutputStream fos = new FileOutputStream(f);                byte[] bytes = new byte[1024];                int length;                while (((length = is.read(bytes)) != -1)) {                    fos.write(bytes, 0, length);                }                os.write("成功".getBytes());                fos.close();                s.close();        } catch (IOException e) {            e.printStackTrace();        }    }}

服务端
Server.java

public class Sever {    public static void main(String[] args) {        try {            ServerSocket ss = new ServerSocket(11000);            while (true) {                Socket s = ss.accept();                new Thread(new UserThread(s)).start();            }            } catch(IOException e){                e.printStackTrace();            }    }}
