spring boot udp或者tcp接收數據

下面用的是 springboot內置integration依賴

<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>

 

下面是一個類 用來接收udp協議和tcp協議的數據

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);//實例化一個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());//把接收的數據轉化為字符串
    }
    
    @Filter(inputChannel="udpString",outputChannel="udpFilter")
    public boolean filter(String message) {
        return message.startsWith("abc");//如果接收數據開頭不是abc直接過濾掉
    }
    

    
   @Router(inputChannel="udpFilter")
    public String routing(String message) {
        if(message.contains("1")) {//當接收數據包含數字1時
            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()));
    }


}
