SpringBoot集成多个rabbitmq

article 2024/11/25 22:03:06

1、pom文件

<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-amqp -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-amqp</artifactId>
    <version>2.4.9</version>
</dependency>

2、rabbitmq的连接配置文件

spring:
  rabbitmq:
    mq1:
      host: xxx.xxx.xxx.xxx
      port: 5672
      username: xxxx
      password: xxxxx
      enable: true
    mq2:
      host: xxx.xxx.xxx.xxx
      port: 5672
      username: xxxxx
      password: xxxxx
      enable: true

 * </p>
 *
 * @author zhushangjin
 * @menu 项目管理
 * @since 2022-11-14
 */
@RestController
@Slf4j
public class ProjectController extends BaseController {

    @Resource(name = "mq1RabbitTemplate")
    //初始化mq1的RabbitTemplate对象
    private RabbitTemplate mq1RabbitTemplate;

    @Resource(name = "mq2RabbitTemplate")
    //初始化mq1的RabbitTemplate对象
    private RabbitTemplate mq2RabbitTemplate;


    /**
     * 获取项目下拉列表
     *
     * @return

        //发送到topicExchangeOne类型的交换机，根据routekey去找发送到哪个队列里，
        // 只有这一个队列才能收到这条消息
        String str = "test1test1test1test1test1";
        mq1RabbitTemplate.convertAndSend("topicExchangeOne","subQueue01", str);
        return buildResponseResult(true);

    }

    @GetMapping("/prj/project/test2")
    public ResponseResult test2() {
        //发送到direct类型的交换机，根据routekey去找发送到哪个队列里，
        //只有这一个队列才能收到这条消息
        mq2RabbitTemplate.convertAndSend("subQueue02", "test2test2test2test2test2");

        // 故第二个参数routekey无需填写
        mq1RabbitTemplate.convertAndSend("fanoutExchangeOne", null, "test3test3test3test3test3");
        return buildResponseResult(true);

    }


}

6、消息消费者

Receiver1.java

package com.pojo.config;

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
@RabbitListener(queues = "subQueue01", containerFactory = "simpleRabbitListenerContainerFactory1")
public class Receiver1 {

    @RabbitHandler(isDefault = true)
    public void process(String hello) {
        System.out.println("Receiver1: " + hello);
    }

}

Receiver2.java

package com.pojo.config;

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
@RabbitListener(queues = "subQueue02", containerFactory = "simpleRabbitListenerContainerFactory2")
public class Receiver2 {

     @RabbitHandler(isDefault = true)
    public void process(String hello) {
        System.out.println("Receiver2: " + hello);
    }

}

Receiver3.java

package com.pojo.config;

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
@RabbitListener(queues = "subQueue03", containerFactory = "simpleRabbitListenerContainerFactory1")
public class Receiver3 {

     @RabbitHandler(isDefault = true)
    public void process(String hello) {
        System.out.println("Receiver3 : " + hello);
    }

}

Receiver4.java

package com.pojo.config;

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
@RabbitListener(queues = "subQueue04", containerFactory = "simpleRabbitListenerContainerFactory1")
public class Receiver4 {

    @RabbitHandler(isDefault = true)
    public void process(String hello) {
        System.out.println("Receiver4 : " + hello);
    }

}

创建队列

@Bean(name = "uavTopicQueue")
    public Queue topicQueue() {
        Map<String, Object> argsMap = new HashMap<String, Object>();
        argsMap.put("x-max-priority", 5);
        Queue queue = new Queue(UAV_QUEUE, true, false, false, argsMap);
        return queue;
    }
