SpringBoot集成多个rabbitmq

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.xxxport: 5672username: xxxxpassword: xxxxxenable: truemq2:host: xxx.xxx.xxx.xxxport: 5672username: xxxxxpassword: xxxxxenable: true

}

5、消息生产者

package com.pojo.prj.controller;import com.pojo.common.anno.NoNeedLogin;
import com.pojo.common.base.ApplicationContextUtils;
import com.pojo.common.base.BaseController;
import com.pojo.util.ResponseResult;
import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import javax.annotation.Resource;/*** <p>* 项目表 前端控制器* </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* @status done*/@GetMapping("/prj/project/list")@NoNeedLoginpublic ResponseResult<String> list() {String active = ApplicationContextUtils.getActiveProfile();logger.error(ApplicationContextUtils.getActiveProfile());return ResponseResult.ok("ReturnCallBack2");}@GetMapping("/prj/project/test1")public ResponseResult test1() {//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");return buildResponseResult(true);}@GetMapping("/prj/project/test3")public ResponseResult test3() {//发送到fanout类型的交换机，跟这个交换机绑定的队列都会收到这一条消息，// 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;}
