Question

尝试制作测试客户端 - 服务器应用程序并遇到此问题

Channel channel = bootstrap.connect(host, port).sync().channel();

Bootstrap的类没有与arg类型String，int连接的方法。我怎样才能获得频道？

public class ChatClient {

    private final String host;
    private final int port;

    public static void main(String[] args) throws Exception{
        new ChatClient("localhost", 8080).run();
    }

    public ChatClient(String host, int port) {
        this.host = host;
        this.port = port;
    }

    public void run() throws Exception {
        EventLoopGroup group = new NioEventLoopGroup();

        try{
            Bootstrap bootstrap = new Bootstrap()
                .group(group)
                .channel(NioSocketChannel.class)
                .handler(new ChatClientInitializer());

            Channel channel = bootstrap.connect(host, port).sync().channel();
            BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

            while(true){
                channel.write(in.readLine() + "\r\n");
            }
        }
        finally{

        }
    }
}

它有......确保你依赖4 +的正确netty版本。

请参阅： https://github.com/netty/netty/blob/4.0/transport/src/main/java/io/netty/bootstrap/Bootstrap.java#L95

Bootstrap类没有方法（String host，int port）
