JAVA -------- 创建TCP服务传递数据

Posted 2023-02-16 Java璐到底

话不多说直接上代码，运行的时候先启动服务端，在启动客户端

客户端：

import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.*;
import java.net.Socket;
import java.net.UnknownHostException;
import java.nio.channels.WritableByteChannel;

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.JTextField;
import javax.swing.border.BevelBorder;

public class Tcp_Cliect
    public static void main(String[] args) 

        try 

//创建一个客户端socket

            Socket socket = new Socket("localhost",8888);
         
//向服务器端传递信息

            OutputStream ots = socket.getOutputStream();

            PrintWriter pw = new PrintWriter(ots);

            pw.write("111222123");

            pw.flush();

//关闭输出流

            socket.shutdownOutput();

//获取服务器端传递的数据

            InputStream is = socket.getInputStream();

            InputStreamReader isr = new InputStreamReader(is,"UTF-8");

            BufferedReader br = new BufferedReader(isr);

            String info = null;

            while((info=br.readLine())!=null)

                System.out.println("我是客户端，服务器说："+info);

            

//关闭资源

            br.close();

            isr.close();

            is.close();

            pw.close();

            ots.close();

            socket.close();

         catch (UnknownHostException e) 

            e.printStackTrace();

         catch (IOException e) 

            e.printStackTrace();

        

    

服务端：

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;

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

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

public class Tcp_service
    private BufferedReader reader;
    private ServerSocket serverSocket;
    private Socket socket;
    /**
     * 创建服务端的程序，读取客户端传来的数据
     */
    void getserver()
        try
            serverSocket = new ServerSocket(8888);        //实例化服务端socket
            System.out.println("服务器套接字已经创建成功");
            while (true)
                System.out.println("等待客户机的连接:");
                socket = serverSocket.accept();        //实例化socket对象
                reader = new BufferedReader(new InputStreamReader(socket.getInputStream(),"UTF-8"));    //实例化BufferReader对象
                getClientMessage();
           
        catch (Exception e)
            e.printStackTrace();
       

   

    private void getClientMessage()
        try
            String message = null;
            while ((message = reader.readLine())!=null)
                System.out.println("客户机传来的信息是："+message);
                OutputStreamWriter osw = new OutputStreamWriter(socket.getOutputStream(),"UTF-8");
               // PrintWriter out = new PrintWriter(osw,);
                PrintWriter  pw = new PrintWriter(osw,true);
                pw.println("服务端已接收");
           
        catch (Exception e)
            e.printStackTrace();
       
   

    public static void main(String[] args)
        Tcp_service myTcp = new Tcp_service();            //创建本类对象
        myTcp.getserver();
