Example 6 with OioEventLoopGroup

use of io.netty.channel.oio.OioEventLoopGroup in project cradle by BingLau7.

the class NettyOioServer method server.

public void server(int port) throws Exception {
    final ByteBuf buf = Unpooled.unreleasableBuffer(Unpooled.copiedBuffer("Hi!\r\n", Charset.forName("UTF-8")));
    EventLoopGroup group = new OioEventLoopGroup();
    try {
        // 创建 ServerBootstrap
        ServerBootstrap b = new ServerBootstrap();
        b.group(group).channel(OioServerSocketChannel.class).localAddress(new InetSocketAddress(port)).childHandler(new ChannelInitializer<SocketChannel>() {

            @Override
            public void initChannel(SocketChannel ch) throws Exception {
                // 添加一个 ChannelInBoundHandlerAdapter 以拦截和处理事件
                ch.pipeline().addLast(new ChannelInboundHandlerAdapter() {

                    @Override
                    public void channelActive(ChannelHandlerContext ctx) throws Exception {
                        // 将消息写到客户端，并添加 ChannelFutureListener 以便消息已被写完就关闭连接
                        ctx.writeAndFlush(buf.duplicate()).addListener(ChannelFutureListener.CLOSE);
                    }
                });
            }
        });
        // 绑定服务器以接收连接
        ChannelFuture f = b.bind().sync();
        f.channel().closeFuture().sync();
    } finally {
        // 释放所有资源
        group.shutdownGracefully().sync();
    }
}

Example 7 with OioEventLoopGroup

use of io.netty.channel.oio.OioEventLoopGroup in project intellij-community by JetBrains.

        return start(new OioEventLoopGroup(1, threadFactory), true, 6942, 50, false, handler);
    }
