java gui 接收http请求 写一段代码给我

好的，以下是一个简单的 Java GUI 程序，可以通过该程序启动一个基于 ServerSocket 的 HTTP 服务器，并在窗口中展示服务器的运行状态：

import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;

import javax.swing.*;

public class HttpServerGui extends JFrame implements ActionListener {
    private JTextArea logArea;
    private JButton startButton, stopButton;
    private JTextField portField;
    private ServerSocket serverSocket;
    private Thread serverThread;

    public HttpServerGui() {
        // 设置窗口标题
        super("HTTP Server");

        // 设置窗口大小
        setSize(500, 300);

        // 创建窗口组件
        logArea = new JTextArea();
        JScrollPane scrollPane = new JScrollPane(logArea);
        startButton = new JButton("Start");
        startButton.addActionListener(this);
        stopButton = new JButton("Stop");
        stopButton.addActionListener(this);
        portField = new JTextField("8080");

        // 将组件添加到窗口中
        Container contentPane = getContentPane();
        contentPane.setLayout(new BorderLayout());
        contentPane.add(scrollPane, BorderLayout.CENTER);
        JPanel buttonPanel = new JPanel();
        buttonPanel.add(startButton);
        buttonPanel.add(stopButton);
        buttonPanel.add(new JLabel("Port:"));
        buttonPanel.add(portField);
        contentPane.add(buttonPanel, BorderLayout.SOUTH);

        // 设置窗口可见性
        setVisible(true);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == startButton) {
            startServer();
        } else if (e.getSource() == stopButton) {
            stopServer();
        }
    }

    private void startServer() {
        try {
            // 创建 ServerSocket 对象
            serverSocket = new ServerSocket(Integer.parseInt(portField.getText()));
            log("HTTP server started on port " + serverSocket.getLocalPort() + ".");

            // 创建服务器线程
            serverThread = new Thread(new Runnable() {
                @Override
                public void run() {
                    while (true) {
                        try {
                            // 接收客户端请求
                            Socket clientSocket = serverSocket.accept();
                            log("Client connected from " + clientSocket.getRemoteSocketAddress() + ".");

                            // 读取请求数据
                            BufferedReader reader = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
                            String requestLine = reader.readLine();
                            log("Request line: " + requestLine);

                            // 响应客户端请求
                            String response = "HTTP/1.1 200 OK\r\nContent-Type: text/plain\r\n\r\nHello, world!";
                            OutputStream output = clientSocket.getOutputStream();
                            output.write(response.getBytes());

                            // 关闭连接
                            output.close();
                            reader.close();
                            clientSocket.close();
                            log("Connection closed.");
                        } catch (IOException ex) {
                            log("Error: " + ex.getMessage());
                        }
                    }
                }
            });
            serverThread.start();
        } catch (IOException ex) {
            log("Error: " + ex.getMessage());
        }
    }

    private void stopServer() {
        try {
            // 停止服务器线程
            if (serverThread != null) {
                serverThread.interrupt();
                serverThread.join();
                serverThread = null;
            }

            // 关闭 ServerSocket
            if (serverSocket != null) {
                serverSocket.close();
                serverSocket = null;
            }

            log("HTTP server stopped.");
        } catch (IOException ex) {
            log("Error: " + ex.getMessage());
        } catch (InterruptedException ex) {
            // ignore
        }
    }

    private void log(String message) {
        logArea.append(message + "\n");
    }

    public static void main(String[] args) {
        new HttpServerGui();
    }
}

注意：上述代码仅为演示程序，不适用于生产环境。在实际应用中，需要根据具体业务需求进行优化和改进。
