Answer 2

HttpRequestHandler -- HTTP请求处理类
TextWebSocketFrameHandler -- 对应Text消息的处理类
WebSocketServer -- 系统主类
WebSocketServerInitializer -- 服务主程序的初始化类
WebSocketServer 类代码：
import io.netty.bootstrap.ServerBootstrap;
import io.netty.channel.ChannelFuture;
import io.netty.channel.ChannelOption;
import io.netty.channel.EventLoopGroup;
import io.netty.channel.nio.NioEventLoopGroup;
import io.netty.channel.socket.nio.NioServerSocketChannel;
public final class WebSocketServer {
private int port = 0;
public WebSocketServer(int port) {
this.port = port;
}
