新建netty服务
public void run(int port) throws Exception {
EventLoopGroup eventLoopGroup = new NioEventLoopGroup();
try {
Bootstrap bootstrap = new Bootstrap()
.group(eventLoopGroup)
.channel(NioDatagramChannel.class)
.option(ChannelOption.SO_BROADCAST, true)
.handler(new ProverbServerHandler());
bootstrap.bind(port).sync().channel().closeFuture().await();
} catch (InterruptedException e) {
e.printStackTrace();
} finally {
eventLoopGroup.shutdownGracefully();
}
}
新建handler
public class ProverbServerHandler extends ChannelInboundHandlerAdapter {
@Override
public void channelRead(ChannelHandlerContext ctx, Object msg) {
// 接收数据
DatagramPacket packet = (DatagramPacket) msg;
ByteBuf byteBuf1 = new UnpooledByteBufAllocator(false).buffer();
// 刷新
ctx.writeAndFlush(new DatagramPacket(byteBuf1, packet.sender()));
}
@Override
public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) {
cause.printStackTrace();
}
}
我会写代码+代码改变世界=我会改变世界!
为什么要改变世界?
如果无法改变世界,那么,世界就会改变我......
