如何在SpringBoot中集成Netty

在Spring Boot中集成Netty可以通过以下步骤实现:
1. 添加Netty依赖
在pom.xml文件中添加以下依赖:
```xml
<dependency>
<groupId>io.netty</groupId>
<artifactId>netty-all</artifactId>
<version>4.1.25.Final</version>
</dependency>
```
2. 创建Netty服务
创建一个Netty服务类,实现ChannelInboundHandlerAdapter:
```java
public class NettyServerHandler extends ChannelInboundHandlerAdapter {
@Override
public void channelActive(ChannelHandlerContext ctx) throws Exception {
System.out.println("Channel Active");
}
@Override
public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
System.out.println("Channel Read");
ctx.writeAndFlush(msg);
}
@Override
public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) throws Exception {
System.out.println("Exception Caught");
cause.printStackTrace();
ctx.close();
}
}
```
3. 创建Netty配置类
创建一个Netty配置类,实现InitializingBean和DisposableBean接口:
```java
@Configuration
public class NettyConfig implements InitializingBean, DisposableBean {
private EventLoopGroup bossGroup = new NioEventLoopGroup();
private EventLoopGroup workerGroup = new NioEventLoopGroup();
private ServerBootstrap serverBootstrap;
@Autowired
private NettyServerHandler nettyServerHandler;
@Override
public void afterPropertiesSet() throws Exception {
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);
}
});
serverBootstrap.bind(8080).sync();
}
@Override
public void destroy() throws Exception {
bossGroup.shutdownGracefully();
workerGroup.shutdownGracefully();
}
}
```
4. 测试Netty服务
启动Spring Boot应用,访问http://localhost:8080,在控制台中可以看到Netty服务已经启动。
