（JAVA）TCP通信-客户端数据来自文件，输出到服务器指定文本文件，并给出反馈

1.客户端发送数据代码

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

public class ClinetDemo2 {
    
    
    public static void main(String[] args) throws IOException {
    
    
        Socket s = new Socket("zshao",10001);
        //
        BufferedReader br = new BufferedReader(new FileReader("d/Demo.java"));
        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
        String line;
        while ((line=br.readLine())!=null){
    
    
            bw.write(line);
            bw.newLine();
            bw.flush();
        }
        //输出结束标记
        s.shutdownOutput();
        //接受反馈
        BufferedReader brClient = new BufferedReader(new InputStreamReader(s.getInputStream()));
        String data = brClient.readLine();
        System.out.println("服务器的反馈为："+data);
        br.close();
        s.close();
    }

2.服务器接受数据代码

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

//服务器接受的数据写到文件中
public class ServerDemo2 {
    
    
    public static void main(String[] args) throws IOException {
    
    
        //创建服务器Socket对象
        ServerSocket ss = new ServerSocket(10001);
        //监听客户端连接，返回Socket对象
        Socket s = ss.accept();
        //接受数据
        BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));
        //把数据写入文本文件
        BufferedWriter bw = new BufferedWriter(new FileWriter("java/s.java"));
        String line;
        while ((line=br.readLine())!=null){
    
    
            bw.write(line);
            bw.newLine();
            bw.flush();
        }
                //给客户端一个反馈
        BufferedWriter bwServer = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
        bwServer.write("文件传输成功！");
        bwServer.newLine();
        bwServer.flush();
        bw.close();
        ss.close();
    }
}
