更改消费模块的主启动类

package com.gcl.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@EnableEurekaClient
@SpringBootApplication
public class StreamRabbitMQMain8802 {

    public static void main(String[] args) {
        SpringApplication.run( StreamRabbitMQMain8802.class , args );
    }

}

更改消费模块的业务类

package com.gcl.springcloud.service;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.cloud.stream.annotation.EnableBinding;
import org.springframework.cloud.stream.annotation.StreamListener;
import org.springframework.cloud.stream.messaging.Sink;
import org.springframework.messaging.Message;
import org.springframework.stereotype.Component;

@Component
@EnableBinding(Sink.class)
public class StreamRabbitMQService {

    @Value("${server.port}")
    private String serverPort;

    @StreamListener(Sink.INPUT)
    public void input(Message message){
        System.out.println("***************接收到的消息：" + message.getPayload() + " server.port : " + serverPort );
    }

}
