基于tcp协议的socket客户端与服务端的通信-java

描述：基于tcp的Socket与ServerSocket的通信，客户端和服务端的聊天
实现语言：java
一：服务端的代码
1：服务端的键盘录入代码

package chat;

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

public class ServerWrit implements Runnable{
    Socket socket;
public ServerWrit(Socket socket){
this.socket=socket;
    }
public void run(){
try {
            BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
            BufferedWriter bw=new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
            String line="";
while((line=br.readLine())!=null){
                bw.write(line+"\r\n");
                bw.flush();
            }
            socket.close();
        } catch (IOException e) {
// TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

2：读取客户端发来的信息：

package chat;

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

public class ServerRead implements Runnable{
    Socket socket;
public ServerRead(Socket socket){
this.socket=socket;
    }
public void run(){
try {
//获得输入
            BufferedReader read=new BufferedReader(new InputStreamReader(socket.getInputStream()));

//进行读取
            String str="";
while((str=read.readLine())!=null){
                System.out.println("接受到客户端的话："+str);
            }
        } catch (IOException e) {
// TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

3：服务端的启动代码：

package chat;

import java.net.ServerSocket;
import java.net.Socket;

public class ServerTest {
public static void main(String[] args) throws Exception {
        ServerSocket servers=new ServerSocket(9090);
        Socket socket=servers.accept();

new Thread(new ServerRead(socket)).start();
new Thread(new ServerWrit(socket)).start();
//servers.close(); 
    }

}

二：客户端的实现：
1：键盘录入线程

package chat;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.Socket;

public class ClinckWrit implements Runnable{
    Socket socket;
public ClinckWrit(Socket socket){
this.socket=socket;
    }
public void run(){
try {
//获得输出流
            BufferedWriter bw=new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));

//获得输入流
            BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

            String str="";
while((str=br.readLine())!=null){
                bw.write(str+"\r\n");
                bw.flush();
            }
        }  catch (IOException e) {
            e.printStackTrace();
        }

    }

}

2：读取客户端的消息线程

package chat;

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

public class ClientRead implements Runnable{
    Socket socket;
public ClientRead(Socket socket){
this.socket=socket;
    }
public void run(){
try {
            BufferedReader br =new BufferedReader(new InputStreamReader(socket.getInputStream()));
            String str="";
while((str=br.readLine())!=null){
                System.out.println("服务端回应："+str);
            }
            socket.close();
        } catch (IOException e) {
// TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

3：启动客户端的程序

package chat;

import java.net.InetAddress;
import java.net.Socket;

public class ClientT {
public static void main(String[] args) throws Exception {
        Socket socket=new Socket(InetAddress.getLocalHost(),9090);
new Thread(new ClinckWrit(socket)).start();
new Thread(new ClientRead(socket)).start();
    }
}

先启动服务端，然后再启动客户端，这样就可以愉快地聊天了
稍作改动就可以做成群聊了
