TCP模拟实现文本文件上传Java代码

多线程Main代码：

    new Thread(new TextUploadServer()).start();
    new Thread(new TextUploadClient()).start();

客户端代码：

 1 public class TextUploadClient implements Runnable {
 2     @Override
 3     public void run() {
 4         try {
 5             Socket socket = new Socket(InetAddress.getLocalHost(), 50001);
 6             String path = "D:\\src.txt";
 7             BufferedReader bufferedReader = new BufferedReader(new FileReader(path));
 8             //可用PrintWriter代替，更简单
 9             BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
10             
11             String line = null;
12             while((line = bufferedReader.readLine()) != null){
13                 bufferedWriter.write(line);//只需改为printWriter.println(line);
14                 bufferedWriter.newLine();
15                 bufferedWriter.flush();
16             }
17             socket.shutdownOutput();
18             
19             BufferedReader backReader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
20             String res = backReader.readLine();
21             
22             System.out.println(res);
23             
24             bufferedReader.close();
25             socket.close();
26         }
27         catch (Exception e) {
28             e.printStackTrace();
29         }
30     }
31 
32 }

服务端代码实现：

 1 public class TextUploadServer implements Runnable {
 2 
 3     @Override
 4     public void run() {
 5         
 6         try {
 7             ServerSocket ss = new ServerSocket(50001);
 8             Socket socket = ss.accept();
 9             
10             BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
11             BufferedWriter bufferedWriter = new BufferedWriter(new FileWriter("D:\\tar.txt"));
12             
13             String line = null;
14             while((line = bufferedReader.readLine()) != null){
15                 bufferedWriter.write(line);
16                 bufferedWriter.newLine();
17                 //bufferedWriter.flush();
18             }
19             
20             BufferedWriter returnWriter = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
21             returnWriter.write("Txt文本上传成功！！");
22             returnWriter.newLine();
23             returnWriter.flush();
24             
25             bufferedWriter.close();
26             socket.close();
27             ss.close();
28             
29         }
30         catch (Exception e) {
31             // TODO Auto-generated catch block
32             e.printStackTrace();
33         }
34         
35         
36     }
37 }
