netty 整合springboot

Spring Boot可以很方便地与Netty集成,实现高性能的网络应用程序。
首先,需要在pom.xml文件中添加Netty的依赖:
```
<dependency>
<groupId>io.netty</groupId>
<artifactId>netty-all</artifactId>
<version>4.1.25.Final</version>
</dependency>
```
然后,在Spring Boot的启动类中,创建一个Netty的ServerBootstrap实例,并将其绑定到指定的端口上:
```
@Configuration
public class NettyConfig {
@Value("${netty.port}")
private int port;
@Autowired
private NettyServerHandler nettyServerHandler;
@Bean
public EventLoopGroup bossGroup() {
return new NioEventLoopGroup();
}
@Bean
public EventLoopGroup workerGroup() {
return new NioEventLoopGroup();
}
@Bean
public ServerBootstrap serverBootstrap() {
ServerBootstrap serverBootstrap = new ServerBootstrap();
serverBootstrap.group(bossGroup(), workerGroup())
.channel(NioServerSocketChannel.class)
.childHandler(new ChannelInitializer<SocketChannel>() {
@Override
protected void initChannel(SocketChannel ch) throws Exception {
ch.pipeline().addLast(nettyServerHandler);
}
});
return serverBootstrap;
}
@Bean
public InetSocketAddress inetSocketAddress() {
return new InetSocketAddress(port);
}
@Bean
public ChannelFuture channelFuture() throws InterruptedException {
return serverBootstrap().bind(inetSocketAddress()).sync();
}
}
```
其中,NettyServerHandler是自定义的处理器,用于处理客户端的请求。
最后,在NettyServerHandler中实现具体的业务逻辑:
```
@Component
@ChannelHandler.Sharable
public class NettyServerHandler extends ChannelInboundHandlerAdapter {
@Override
public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
// 处理客户端的请求
}
@Override
public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) throws Exception {
// 处理异常
}
}
```
这样,就完成了Spring Boot与Netty的整合。可以通过访问指定的端口,来调用NettyServerHandler中实现的业务逻辑。
