三、启动类：

package cn.edu.tju;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.stream.annotation.EnableBinding;
import org.springframework.cloud.stream.messaging.Sink;
import org.springframework.cloud.stream.messaging.Source;

@SpringBootApplication
@EnableBinding({Source.class , Sink.class })
public class Start {
    public static void main(String[] args) {
        SpringApplication.run(Start.class, args);
    }
}

四、发送消息的controller

package cn.edu.tju.controller;


import org.apache.rocketmq.common.message.MessageConst;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.messaging.Message;
import org.springframework.messaging.MessageChannel;
import org.springframework.messaging.MessageHeaders;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

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


@RestController
public class SendController {
    @Resource
    private MessageChannel output;
    @GetMapping("/test")
    public String test(){
        String uuid = UUID.randomUUID().toString();
        Map headerMap = new HashMap<>();
        headerMap.put(MessageConst.PROPERTY_TAGS,"testTag");
        MessageHeaders messageHeaders = new MessageHeaders(headerMap);
        Message message = MessageBuilder.createMessage(uuid, messageHeaders);
        boolean b = output.send(message);
        //System.out.println(b);

        return "ok";

    }
}

import org.springframework.cloud.stream.messaging.Sink;
import org.springframework.stereotype.Component;

import java.util.Date;

@Component
public class ReceiveService {
    @StreamListener(Sink.INPUT)
    public void onMessage(String message){
        System.out.print(new Date() + " " + "received: ");
