netty中怎么设置多个业务类？

Question

我在netty中添加了两个业务类，只执行了前面一个，后面的不执行，谁放在前面就执行谁，不知道怎么设置，代码如下：
EventLoopGroup bossGroup = new NioEventLoopGroup();
EventLoopGroup workerGroup = new NioEventLoopGroup();
try {
ServerBootstrap b = new ServerBootstrap();

        b.group(bossGroup, workerGroup)
                .channel(NioServerSocketChannel.class)
                .option(ChannelOption.SO_BACKLOG, 1024)
                //通过NoDelay禁用Nagle,使消息立即发出去，不用等待到一定的数据量才发出去
                .option(ChannelOption.TCP_NODELAY, true)
                .childHandler(new ChildChannelHandler());
        ChannelFuture f = b.bind(port).sync();
        if(f.isSuccess()){System.out.println("服务端启动成功");}
        f.channel().closeFuture().sync();
    } catch (InterruptedException e) {
    } finally {
        bossGroup.shutdownGracefully();
        workerGroup.shutdownGracefully();
    }
}
private class ChildChannelHandler extends ChannelInitializer<SocketChannel> {
    protected void initChannel(SocketChannel arg0) throws Exception {
        arg0.pipeline().addLast(new MyHandler());
        arg0.pipeline().addLast(new MySend());
    }

Answer 1

arg0.pipeline().addLast 里面添加handler 可以添加多个handler ，执行顺序是按你添加的顺序来执行的
