更改生产模块的yml

server:
  port: 8801

eureka:
  client:
    register-with-eureka: true
    fetch-registry: true
    service-url:
      defaultZone: http://127.0.0.1:7001/eureka/

spring:
  application:
    name: cloud-stream-rabbitmq-provider
  rabbitmq:
    host: xxx.xx.xx.xx
    port: 5672
    username: guest
    password: guest
  cloud:
    stream:
      binders:
        defaultRabbit:
          type: rabbit
      bindings:
        output:
          destination: studyExchange
          content-type: application/json
          binder: defaultRabbit

更改生产模块的主启动类

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 StreamRabbitMQMain8801 {

    public static void main(String[] args) {
        SpringApplication.run( StreamRabbitMQMain8801.class, args );
    }

}

更改生产模块的接口类和实现类

package com.gcl.springcloud.service;

public interface StreamService {

    String send();

}


package com.gcl.springcloud.service.impl;

import com.gcl.springcloud.service.StreamService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.integration.support.MessageBuilder;
import org.springframework.cloud.stream.annotation.EnableBinding;
import org.springframework.cloud.stream.messaging.Source;
import org.springframework.messaging.MessageChannel;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.UUID;

@EnableBinding(Source.class)
@Service
@Slf4j
public class StreamServiceImpl implements StreamService {

    @Resource
    private MessageChannel output;

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

    @Override
    public String send() {
        String serial = UUID.randomUUID().toString();
        output.send(MessageBuilder.withPayload(serial.getBytes()).build());
        log.info( "****************serial"+ serial + " , server.port : " + serverPort );
        return null;
    }

}

更改生产模块的控制层

package com.gcl.springcloud.controller;

import com.gcl.springcloud.service.StreamService;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;

@RestController
public class StreamRabbitMQController {

    @Resource
    private StreamService service;

    @GetMapping(value = "/sendMessage")
    public String sendMessage(){
        return service.send();
    }

}
