Java Socket C/S聊天 基于Java的Socket编写的C/S聊天程序实现

进阶的JFarmer 人气:0

一个很久以前写的能够支持C/S模式聊天的Demo,利用Java的Socket写的。

只能聊一句就下线,挺low的。

服务器端程序Server

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

public class TestTcpServer {
	public static void main(String[] args) {
		ServerSocket ss = null;
		BufferedReader in = null;
		try {
			ss = new ServerSocket(8888);
			System.out.println("服务器启动");
			Socket socket = ss.accept();
			
			System.out.println("连接建立");
			System.out.println(socket.getInetAddress().getHostAddress());
			
			//服务器接收客户端发送的数据
			in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
			
			String clientContent = in.readLine();
			
			System.out.println("接收客户端消息: " +clientContent);

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

客户端程序Clinet

import java.io.BufferedWriter;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.net.Socket;
import java.net.UnknownHostException;
import java.util.Scanner;

public class TestTcpClient {
	public static void main(String[] args) {
		Socket socket = null;
		BufferedWriter out = null;
		
		//客户端发送数据,服务器端接收
		try {
			socket = new Socket("127.0.0.1",8888);
			System.out.println("与服务器连接了");
			Scanner sc = new Scanner(System.in);
			String content = sc.nextLine();

			out = new BufferedWriter((new OutputStreamWriter(socket.getOutputStream())));
			
			out.write(content);
			out.flush();
   sc.close();
		} catch (UnknownHostException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		} finally{
			try {
				out.close();
			
				socket.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
	}
}

运行样例

注意要先起S端,否则:


好啦,先起S端:


然后S端就在等待,它“说话”也没人理它:


接着起C端:


S端也会有响应:


然后C端发消息:


S端收到消息,就双双Over了:
