Java 利用 Netty 实现带解码器与粘包处理器的 WebSocket 启动类

```java import io.netty.bootstrap.ServerBootstrap; import io.netty.channel.ChannelFuture; import io.netty.channel.ChannelInitializer; import io.netty.channel.ChannelOption; import io.netty.channel.EventLoopGroup; import io.netty.channel.nio.NioEventLoopGroup; import io.netty.channel.socket.SocketChannel; import io.netty.channel.socket.nio.NioServerSocketChannel; import io.netty.handler.codec.http.HttpObjectAggregator; import io.netty.handler.codec.http.HttpServerCodec; import io.netty.handler.codec.http.websocketx.WebSocketServerProtocolHandler; import io.netty.handler.stream.ChunkedWriteHandler; public class WebSocketServer { public static void main(String[] args) throws InterruptedException { // 创建 boss 和 worker 线程组 EventLoopGroup bossGroup = new NioEventLoopGroup(); EventLoopGroup workerGroup = new NioEventLoopGroup(); try { ServerBootstrap bootstrap = new ServerBootstrap(); bootstrap.group(bossGroup, workerGroup) .channel(NioServerSocketChannel.class) .childHandler(new ChannelInitializer<SocketChannel>() { @Override protected void initChannel(SocketChannel ch) throws Exception { // 解码器 ch.pipeline().addLast(new HttpServerCodec()); ch.pipeline().addLast(new HttpObjectAggregator(65536)); ch.pipeline().addLast(new ChunkedWriteHandler()); // 粘包处理器 // 这里假设您有自定义的粘包处理器类 CustomPacketHandler ch.pipeline().addLast(new CustomPacketHandler()); // WebSocket 协议处理器 ch.pipeline().addLast(new WebSocketServerProtocolHandler("/ws")); } }) .option(ChannelOption.SO_BACKLOG, 128) .childOption(ChannelOption.SO_KEEPALIVE, true); ChannelFuture future = bootstrap.bind(8080).sync(); future.channel().closeFuture().sync(); } finally { bossGroup.shutdownGracefully(); workerGroup.shutdownGracefully(); } } } ``` // 额外注意点： // 1. 确保自定义的粘包处理器类 `CustomPacketHandler` 实现了正确的逻辑。 // 2. 处理好异常情况，特别是在网络通信中可能出现的各种异常。 // 3. 根据实际需求合理配置服务器的参数，如线程数量、缓冲区大小等。 ######[AI写代码神器 | 573点数解答 | 2025-01-17 17:47:00]
