spring boot udp或者tcp接收数据的实例详解
下面用的是 springboot内置integration依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-integration</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework.integration</groupId> <artifactId>spring-integration-ip</artifactId> </dependency>
下面是一个类 用来接收udp协议和tcp协议的数据
import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.integration.annotation.Filter; import org.springframework.integration.annotation.Router; import org.springframework.integration.annotation.ServiceActivator; import org.springframework.integration.annotation.Transformer; import org.springframework.integration.ip.tcp.TcpReceivingChannelAdapter; import org.springframework.integration.ip.tcp.connection.TcpNetServerConnectionFactory; import org.springframework.integration.ip.tcp.serializer.ByteArrayRawSerializer; import org.springframework.integration.ip.udp.UnicastReceivingChannelAdapter; import org.springframework.messaging.Message; @Configuration public class DataReceiveConfigration { @Bean public UnicastReceivingChannelAdapter getUnicastReceivingChannelAdapter() { UnicastReceivingChannelAdapter adapter = new UnicastReceivingChannelAdapter(4567);//实例化一个udp 4567端口 adapter.setOutputChannelName("udp"); return adapter; } @Transformer(inputChannel="udp",outputChannel="udpString") public String transformer(Message<?> message) { return new String((byte[])message.getPayload());//把接收的数据转化为字符串 } @Filter(inputChannel="udpString",outputChannel="udpFilter") public boolean filter(String message) { return message.startsWith("abc");//如果接收数据开头不是abc直接过滤掉 } @Router(inputChannel="udpFilter") public String routing(String message) { if(message.contains("1")) {//当接收数据包含数字1时 return "udpRoute1"; } else { return "udpRoute2"; } } @ServiceActivator(inputChannel="udpRoute1") public void udpMessageHandle(String message) { System.out.println("udp1:" +message); } @ServiceActivator(inputChannel="udpRoute2") public void udpMessageHandle2(String message) { System.out.println("udp2:" +message); } @Bean public TcpNetServerConnectionFactory getServerConnectionFactory() { TcpNetServerConnectionFactory serverConnectionFactory = new TcpNetServerConnectionFactory(1234); serverConnectionFactory.setSerializer(new ByteArrayRawSerializer()); serverConnectionFactory.setDeserializer(new ByteArrayRawSerializer()); serverConnectionFactory.setLookupHost(false); return serverConnectionFactory; } @Bean public TcpReceivingChannelAdapter getReceivingChannelAdapter() { TcpReceivingChannelAdapter receivingChannelAdapter = new TcpReceivingChannelAdapter(); receivingChannelAdapter.setConnectionFactory(getServerConnectionFactory()); receivingChannelAdapter.setOutputChannelName("tcp"); return receivingChannelAdapter; } @ServiceActivator(inputChannel="tcp") public void messageHandle(Message<?> message) { System.out.println(new String((byte[])message.getPayload())); } }
