Apache Mina:如何编写Http服务器？

import org.apache.mina.core.service.IoAcceptor;
import org.apache.mina.core.session.IoSession;
import org.apache.mina.filter.codec.ProtocolCodecFilter;
import org.apache.mina.filter.codec.textline.TextLineCodecFactory;
import org.apache.mina.transport.socket.nio.NioSocketAcceptor;

import java.io.IOException;
import java.net.InetSocketAddress;
import java.nio.charset.Charset;

public class HttpServer {
    private static final int PORT = 8080;

    public static void main(String[] args) {
        IoAcceptor acceptor = new NioSocketAcceptor();
        acceptor.getFilterChain().addLast("codec", new ProtocolCodecFilter(new TextLineCodecFactory(Charset.forName("UTF-8"))));
        acceptor.setHandler(new HttpRequestHandler());

        try {
            acceptor.bind(new InetSocketAddress(PORT));
            System.out.println("HttpServer started on port " + PORT);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

import org.apache.mina.core.service.IoHandlerAdapter;
import org.apache.mina.core.session.IoSession;

public class HttpRequestHandler extends IoHandlerAdapter {
    @Override
    public void messageReceived(IoSession session, Object message) throws Exception {
        String request = message.toString();
        // 处理Http请求逻辑，生成响应
        String response = "Hello, World!";
        session.write(response);
    }
}
