如何在Java套接字中创建用于接收数据的监听器

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

int port = 8080; // 监听的端口号
ServerSocket serverSocket = new ServerSocket(port);

Socket clientSocket = serverSocket.accept();

InputStream inputStream = clientSocket.getInputStream();

byte[] buffer = new byte[1024];
int bytesRead = inputStream.read(buffer);
String receivedData = new String(buffer, 0, bytesRead);

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

public class SocketListener {
    public static void main(String[] args) {
        int port = 8080; // 监听的端口号
        try {
            ServerSocket serverSocket = new ServerSocket(port);
            System.out.println("Server listening on port " + port);
            
            Socket clientSocket = serverSocket.accept();
            System.out.println("Client connected: " + clientSocket.getInetAddress().getHostAddress());
            
            InputStream inputStream = clientSocket.getInputStream();
            byte[] buffer = new byte[1024];
            int bytesRead = inputStream.read(buffer);
            String receivedData = new String(buffer, 0, bytesRead);
            System.out.println("Received data: " + receivedData);
            
            // 处理接收到的数据
            
            serverSocket.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
