用 原始AmqpTemplate 模拟多个不同的消费者

比如，一个订单服务，如下单，就可能是下的数码，有的可能下的是水果，数码供应商就只关心数码的消息，水果的只关心水果的。同时这样也可以分压系统，就可以对消息进行分组

消息接收

package com.lm.test.message;


import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.rabbit.annotation.Exchange;
import org.springframework.amqp.rabbit.annotation.Queue;
import org.springframework.amqp.rabbit.annotation.QueueBinding;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;


/**
 * 接收方
 */
@Slf4j
@Component
public class MqReceiver2 {


    //数码供应商服务
    @RabbitListener(bindings = @QueueBinding(
            exchange = @Exchange("myOrder"),
            key = "computer",
            value = @Queue("order-computer")
             ))
    public void processComputer(String message){
        log.info("数码供应商服务 消息接受：{}",message);
    }

    //水果供应商服务
    @RabbitListener(bindings = @QueueBinding(
            exchange = @Exchange("myOrder"),
            key = "fruit",
            value = @Queue("order-fruit")
    ))
    public void processFruit(String message){
        log.info("水果供应商服务 消息接受：{}",message);
    }


}

消息发送

package com.lm.test.controller;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.Date;

//发送MQ测试
@RestController
public class SendMessage2Controller {

    @Autowired
    private AmqpTemplate amqpTemplate;

    @GetMapping("/sendMessage2")
    public void process(){
        String message = "发送的消息："+new Date();
//        amqpTemplate.convertAndSend("myOrder","computer",message);
        amqpTemplate.convertAndSend("myOrder","fruit",message);
    }
}

结果
