Server Interface #

First, an interface of server.

public interface Server extends AutoCloseable {
    /**
     * Start the server.
     */
    void start();
}

Note that Server interface extends AutoCloseable, so that it’s able to use Java try-with clause

try (Server server = new BioServer("localhost", 3128)) {
    server.start();
} catch (Exception e) {
    e.printStackTrace();
}

BioServer #

This is a simple implementation, using ServerSocket.

the start method will loop forever

    public void start() {
        try {
            serverSocket = new ServerSocket();
            serverSocket.bind(new InetSocketAddress(host, port));
            while (true) {
                Socket socket = serverSocket.accept();
                process(socket);
            }
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }

and the request will be processed by RequestProcessor, so that Server code will be simple and clean.
