java完美实现springboot集成rabbitmq

1、application.yml配置rabbitmq连接

# Spring??
spring:
  application:
    name: exchange
  rabbitmq:
    host: rabbitmq-test-old.catles.com
    port: 5672
#   addresses: 192.168.2.22:5672
    username: cbms
    password: cbms123456
    publisher-confirms: true
    publisher-returns: true
    connectionTimeout: 3000ms #???????ms?0????????
    listener:
      simple:
        default-requeue-rejected: true
        retry:
          initial-interval: 30000ms
          enabled: true
          max-attempts: 3
    virtual-host: /cbms

rabbitmqService:   # rabbitmq? ????????
  topic:
    appData: # ????????????
      exchange: catl-appDataExchange-zyceshi
      routingKey:
        swapStatus: catl-swapStatus-zyceshi # ????
      queueName:
        swapStatus: catl-swapStatusQueue-zy-test-001 # ???????

2、pom.xml配置依赖

<!--        rabbitmq-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

3、rabbitmq生产者和消费者配置

生产者：

package com.example.rabbitmqdemozj.rabbit.producer;

import com.alibaba.fastjson.JSON;
import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author junliu
 * @description 跟app端交互的mq消费者
 * @return
 * @date 2021/5/10 上午10:25
 **/
@Slf4j
@RestController
@RequestMapping("/rabbit")
public class RabbitMqProducer {



    @Value("${rabbitmqService.topic.appData.exchange}")
    private String exchange;

    @Value("${rabbitmqService.topic.appData.routingKey.swapStatus}")
    private String swapStatusKey;

    @Autowired
    private RabbitTemplate rabbitTemplate;



    /**
     * @Description:  生产者消息
     * @return void
     * @Author zangyao
     * @CreateTime 2022/6/20
     */
    @GetMapping("/producerMessage")
    public void producerMessage(){
        for (int i = 0; i < 3; i++) {
            System.out.println("发送："+i);
            rabbitTemplate.convertAndSend(exchange, swapStatusKey, JSON.toJSONString("swapStatusEntity"+i));
        }
    }


}

消费者：

package com.example.rabbitmqdemozj.rabbit.consumer;

import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.core.ExchangeTypes;
import org.springframework.amqp.rabbit.annotation.*;
import org.springframework.stereotype.Component;

/**
 * @author junliu
 * @description 跟app端交互的mq消费者
 * @return
 * @date 2021/5/10 上午10:25
 **/
@Component
@Slf4j
public class RabbitMqConsumer {


    /**
     * @Description: 消费者消息A
     * @return void
     * @Author zangyao
     * @CreateTime 2022/6/20
     */
    @RabbitHandler
    @RabbitListener(bindings = {
            @QueueBinding(
                    exchange = @Exchange(value = "${rabbitmqService.topic.appData.exchange}", type = ExchangeTypes.TOPIC),
                    key = "${rabbitmqService.topic.appData.routingKey.swapStatus}",
                    value = @Queue(value = "${rabbitmqService.topic.appData.queueName.swapStatus}", autoDelete = "false", durable = "true")
            )
    })
    public void consumerMessageA(String msg) {
        System.out.println("rabbit--1:"+msg);

    }

    /**
     * @Description: 消费者消息B
     * @return void
     * @Author zangyao
     * @CreateTime 2022/6/20
     */
    @RabbitHandler
    @RabbitListener(bindings = {
            @QueueBinding(
                    exchange = @Exchange(value = "${rabbitmqService.topic.appData.exchange}", type = ExchangeTypes.TOPIC),
                    key = "${rabbitmqService.topic.appData.routingKey.swapStatus}",
                    value = @Queue(value = "${rabbitmqService.topic.appData.queueName.swapStatus}", autoDelete = "false", durable = "true")
            )
    })
    public void consumerMessageB(String msga) {
        System.out.println("rabbit--2:"+msga);
    }


}
