下面是使用SpringBoot整合Netty实现UDP服务端的代码示例:
首先,在pom.xml文件中添加以下依赖:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>io.netty</groupId>
<artifactId>netty-transport-native-epoll</artifactId>
<version>4.1.63.Final</version>
<classifier>linux-x86_64</classifier>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>io.netty</groupId>
<artifactId>netty-all</artifactId>
<version>4.1.63.Final</version>
</dependency>
```
接下来,创建一个UDP服务器类,如下所示:
```java
import io.netty.bootstrap.Bootstrap;
import io.netty.channel.*;
import io.netty.channel.nio.NioEventLoopGroup;
import io.netty.channel.socket.DatagramPacket;
import io.netty.channel.socket.nio.NioDatagramChannel;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
@Component
public class UdpServer {
@Value("${udp.port}")
private int port;
public void start() throws Exception {
EventLoopGroup group = new NioEventLoopGroup();
try {
Bootstrap bootstrap = new Bootstrap();
bootstrap.group(group)
.channel(NioDatagramChannel.class)
.option(ChannelOption.SO_BROADCAST, true)
.handler(new ChannelInitializer<Channel>() {
@Override
protected void initChannel(Channel ch) throws Exception {
ChannelPipeline pipeline = ch.pipeline();
pipeline.addLast(new UdpServerHandler());
}
});
ChannelFuture future = bootstrap.bind(port).sync();
future.channel().closeFuture().await();
} finally {
group.shutdownGracefully();
}
}
}
```
然后,创建一个UDP服务器处理程序类,如下所示:
```java
import io.netty.channel.ChannelHandlerContext;
import io.netty.channel.SimpleChannelInboundHandler;
import io.netty.channel.socket.DatagramPacket;
public class UdpServerHandler extends SimpleChannelInboundHandler<DatagramPacket> {
@Override
protected void channelRead0(ChannelHandlerContext ctx, DatagramPacket packet) throws Exception {
// 处理接收到的UDP数据包
String message = packet.content().toString(CharsetUtil.UTF_8);
// 在这里进行业务处理
System.out.println("接收到UDP消息:" + message);
}
}
```
最后,在Spring Boot的启动类中添加以下代码:
```java
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application implements CommandLineRunner {
@Autowired
private UdpServer udpServer;
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Override
public void run(String... args) throws Exception {
udpServer.start();
}
}
```
现在,你可以在配置文件中指定UDP服务器的端口号(如application.properties或application.yml),然后运行Spring Boot应用程序来启动UDP服务器。
这样就实现了使用SpringBoot整合Netty实现UDP服务端的代码。你可以根据自己的需求进行进一步的业务处理。
