003socket 基本使用_触发socket事件,消息类型003-优快云博客

本文介绍了一个使用Java实现的Socket通信示例，包括客户端和服务端的代码实现。客户端通过Socket连接到本地服务器，进行数据的读写操作。服务端监听特定端口，接收并处理来自客户端的消息，再将处理后的消息返回给客户端。

package sock;

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

public class MySock3 {

    public static void main(String[] args) throws Exception {
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));//这个是之前使用的。io



        Socket socket = new Socket("127.0.0.1", 12313);
        BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
        BufferedReader bufferedReader1 = new BufferedReader(new InputStreamReader(socket.getInputStream()));

        String line = null;
        String s;

        while ((line = bufferedReader.readLine()) != null) {
            if ("end".equals(line)) {
                break;
            }
            bufferedWriter.write(line);
            bufferedWriter.newLine();
            bufferedWriter.flush();

            s = bufferedReader1.readLine();
            System.out.println("收到"+s);

        }

//        while ()

    }
}

class MySer3{
    public static void main(String[] args) throws Exception {

        ServerSocket serverSocket = new ServerSocket(12313);
        Socket socket = serverSocket.accept();
        BufferedReader bufferedReader1 = new BufferedReader(new InputStreamReader(socket.getInputStream()));
//        BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));//替换
        PrintWriter printWriter = new PrintWriter(socket.getOutputStream(),true);

        String line =null;
        while ((line = bufferedReader1.readLine()) != null) {
            System.out.println("line = " + line);
//            bufferedWriter.write(line.toUpperCase());
//            bufferedWriter.newLine();
//            bufferedWriter.flush();
            printWriter.println(line);
        }

        socket.close();//会有个结束标记。 客户端的read也会自动暂停了。
        serverSocket.close();

    }
}
