一、前言

本篇主要是围绕着 Spring Boot 3.x 与 RabbitMQ 的动态配置集成，比如动态新增 RabbitMQ 交换机、队列等操作。

二、默认RabbitMQ中的exchange、queue动态新增及监听

1、新增RabbitMQ配置

RabbitMQConfig.java

import org.springframework.amqp.rabbit.annotation.EnableRabbit;
import org.springframework.amqp.rabbit.core.RabbitAdmin;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** @className: RabbitConfig* @program: chain* @description: RabbitMQ 配置类* @author: kenny* @create: 2024-10-03 21:59* @version: 1.0.0*/
@Configuration
@EnableRabbit
public class RabbitMQConfig {/*** 创建 RabbitTemplate, 用于发送消息** @return RabbitTemplate*/@Beanpublic RabbitTemplate rabbitTemplate() {return new RabbitTemplate();}/*** 创建 RabbitAdmin, 用于创建 Exchange 和 Queue** @param rabbitTemplate RabbitTemplate* @return RabbitAdmin*/@Beanpublic RabbitAdmin rabbitAdmin(RabbitTemplate rabbitTemplate) {return new RabbitAdmin(rabbitTemplate);}
}

2、新增RabbitMQ动态操作组件

RabbitDynamicConfigService.java

RabbitDynamicConfigService.java 中包含了不同类型Exchange的创建、删除，Queue的创建和删除、绑定Exchange

import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.core.*;
import org.springframework.amqp.rabbit.core.RabbitAdmin;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;import java.util.Map;/*** @className: RabbitDynamicConfigService* @program: chain* @description: 动态创建队列和交换机* @author: kenny* @create: 2024-10-03 23:49* @version: 1.0.0*/
@Slf4j
@Service
public class RabbitDynamicConfigService {/*** 为了解决循环依赖问题*/private final RabbitAdmin rabbitAdmin;private final RabbitListenerService rabbitListenerService;@Autowiredpublic RabbitDynamicConfigService(RabbitAdmin rabbitAdmin,RabbitListenerService rabbitListenerService) {this.rabbitAdmin = rabbitAdmin;this.rabbitListenerService = rabbitListenerService;}/*** 动态创建队列，并持久化** @param queueName 队列名称*/public void createQueue(String queueName) {// 队列持久化Queue queue = new Queue(queueName, true);// 创建队列rabbitAdmin.declareQueue(queue);System.out.println("队列创建成功: " + queueName);}/*** 动态创建队列，并持久化** @param queueName 队列名称*/public void createQueue(String queueName, Boolean isListener) {// 队列持久化Queue queue = new Queue(queueName, true);// 创建队列rabbitAdmin.declareQueue(queue);System.out.println("队列创建成功: " + queueName);if (!isListener) {return;}rabbitListenerService.createListener(queueName);}/*** 动态创建交换机，并持久化** @param exchangeName 交换机名称*/public void createExchange(String exchangeName) {// 交换机持久化DirectExchange exchange = new DirectExchange(exchangeName, true, false);rabbitAdmin.declareExchange(exchange);log.info("交换机创建成功: {}", exchangeName);}// 动态创建 Fanout 交换机public void createDirectExchange(String exchangeName) {DirectExchange fanoutExchange = new DirectExchange(exchangeName, true, false); // 持久化rabbitAdmin.declareExchange(fanoutExchange);log.info("Direct 交换机创建成功: {}", exchangeName);}// 动态创建 Fanout 交换机public void createFanoutExchange(String exchangeName) {FanoutExchange fanoutExchange = new FanoutExchange(exchangeName, true, false); // 持久化rabbitAdmin.declareExchange(fanoutExchange);log.info("Fanout 交换机创建成功: {}", exchangeName);}// 动态创建 Topic 交换机public void createTopicExchange(String exchangeName) {TopicExchange topicExchange = new TopicExchange(exchangeName, true, false); // 持久化rabbitAdmin.declareExchange(topicExchange);log.info("Topic 交换机创建成功: {}", exchangeName);}// 动态创建 Headers 交换机public void createHeadersExchange(String exchangeName) {HeadersExchange headersExchange = new HeadersExchange(exchangeName, true, false); // 持久化rabbitAdmin.declareExchange(headersExchange);log.info("Headers 交换机创建成功: {}", exchangeName);}/*** 动态绑定队列到交换机，并指定路由键** @param queueName    队列名称* @param exchangeName 交换机名称* @param routingKey   路由键*/public void bindQueueToExchange(String queueName, String exchangeName, String routingKey) {Queue queue = new Queue(queueName);DirectExchange exchange = new DirectExchange(exchangeName);Binding binding = BindingBuilder.bind(queue).to(exchange).with(routingKey);rabbitAdmin.declareBinding(binding);log.info("绑定创建成功: {}", queueName + " -> {}", exchangeName + " 使用路由键: {}", routingKey);}/*** 动态绑定队列到交换机，并指定路由键** @param queueName    队列名称* @param exchangeName 交换机名称* @param routingKey   路由键*/public void moreExchangeTypeBindQueueToExchange(String queueName, String exchangeType, String exchangeName, String routingKey, Map<String, Object> headers) {switch (exchangeType) {case "fanout" -> bindQueueToExchange(queueName, exchangeName, routingKey);case "direct" -> bindQueueToDirectExchange(queueName, exchangeName, routingKey);case "topic" -> bindQueueToTopicExchange(queueName, exchangeName, routingKey);case "headers" -> bindQueueToHeadersExchange(queueName, exchangeName, headers);default -> throw new IllegalArgumentException("不支持的交换机类型: " + exchangeType);}}/*** 动态绑定队列到交换机，并指定路由键（exchange: direct）** @param queueName    队列名称* @param exchangeName 交换机名称*/public void bindQueueToFanoutExchange(String queueName, String exchangeName) {Queue queue = new Queue(queueName);FanoutExchange exchange = new FanoutExchange(exchangeName);Binding binding = BindingBuilder.bind(queue).to(exchange);rabbitAdmin.declareBinding(binding);log.info("绑定创建成功: {}", queueName + " -> {}", exchangeName);}/*** 动态绑定队列到交换机，并指定路由键（exchange: direct）** @param queueName    队列名称* @param exchangeName 交换机名称* @param routingKey   路由键*/public void bindQueueToDirectExchange(String queueName, String exchangeName, String routingKey) {Queue queue = new Queue(queueName);DirectExchange exchange = new DirectExchange(exchangeName);Binding binding = BindingBuilder.bind(queue).to(exchange).with(routingKey);rabbitAdmin.declareBinding(binding);log.info("绑定创建成功: {}", queueName + " -> {}", exchangeName + " 使用路由键: {}", routingKey);}/*** 动态绑定队列到交换机，并指定路由键（exchange: topic）** @param queueName    队列名称* @param exchangeName 交换机名称* @param routingKey   路由键*/public void bindQueueToTopicExchange(String queueName, String exchangeName, String routingKey) {Queue queue = new Queue(queueName);TopicExchange exchange = new TopicExchange(exchangeName);Binding binding = BindingBuilder.bind(queue).to(exchange).with(routingKey);rabbitAdmin.declareBinding(binding);log.info("绑定创建成功: {}", queueName + " -> {}", exchangeName + " 使用路由键: {}", routingKey);}/*** 动态绑定队列到交换机，并指定路由键（exchange: headers）** @param queueName    队列名称* @param exchangeName 交换机名称* @param headers      路由键*/public void bindQueueToHeadersExchange(String queueName, String exchangeName, Map<String, Object> headers) {Queue queue = new Queue(queueName);HeadersExchange exchange = new HeadersExchange(exchangeName);Binding binding = BindingBuilder.bind(queue).to(exchange).whereAll(headers).match();rabbitAdmin.declareBinding(binding);log.info("队列 {}", queueName + " 已绑定到 Headers 交换机 {}", exchangeName + "，使用头部匹配规则: {}", headers);}/*** 动态删除队列** @param queueName 队列名称*/public void deleteQueue(String queueName) {rabbitAdmin.deleteQueue(queueName);log.info("队列删除成功: {}", queueName);}/*** 动态删除交换机** @param exchangeName 交换机名称*/public void deleteExchange(String exchangeName) {rabbitAdmin.deleteExchange(exchangeName);log.info("交换机删除成功: {}", exchangeName);}
}

3、RabbitMQ中队列的动态监听

RabbitListenerService.java

import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.rabbit.config.SimpleRabbitListenerContainerFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer;
import org.springframework.amqp.rabbit.listener.adapter.MessageListenerAdapter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;/*** @className: RabbitListenerService* @program: chain* @description: RabbitMQ监听器Service组件* @author: kenny* @create: 2024-10-04 01:40* @version: 1.0.0*/
@Slf4j
@Service
public class RabbitListenerService {// 为了解决循环依赖问题private final SimpleRabbitListenerContainerFactory listenerContainerFactory;private final ConnectionFactory connectionFactory;@Autowiredpublic RabbitListenerService(SimpleRabbitListenerContainerFactory listenerContainerFactory,ConnectionFactory connectionFactory) {this.listenerContainerFactory = listenerContainerFactory;this.connectionFactory = connectionFactory;}/*** 创建监听器容器并启动监听** @param queueName 队列名称*/public void createListener(String queueName) {// 创建并启动监听器容器SimpleMessageListenerContainer container = listenerContainerFactory.createListenerContainer();container.setConnectionFactory(connectionFactory);container.setQueueNames(queueName);// 监听逻辑处理container.setMessageListener(new MessageListenerAdapter(new Object() {public void handleMessage(String message) {System.out.println("收到来自RabbitMQ中队列：" + queueName + " 队列的消息：" + message);}}));// 启动监听器容器container.start();System.out.println("RabbitMQ队列监听器已启动：" + queueName);}
}

4、RabbitMQ中的Exchange、Queue动态操作接口

RabbitDynamicChannelController.java

import com.chain.air.rpp.exchange.rabbit.RabbitDynamicConfigService;
import jakarta.annotation.Resource;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;import java.util.HashMap;
import java.util.Map;/*** @className: RabbitDynamicController* @program: chain* @description: RabbitMQ 动态创建队列、交换机，绑定等操作* @author: kenny* @create: 2024-10-04 00:22* @version: 1.0.0*/
@RestController
@RequestMapping("/rabbit/dynamic/channel")
public class RabbitDynamicChannelController {/*** 动态创建队列和交换机*/@Resourceprivate RabbitDynamicConfigService rabbitDynamicConfigService;/*** 动态创建队列** @param queueName 队列名称* @return 处理结果*/@GetMapping("/createQueue")public String createQueue(@RequestParam("queueName") String queueName) {rabbitDynamicConfigService.createQueue(queueName);return "队列已创建: " + queueName;}/*** 动态创建交换机** @param exchangeName 交换机名称* @return 处理结果*/@GetMapping("/createExchange")public String createExchange(@RequestParam("exchangeName") String exchangeName) {rabbitDynamicConfigService.createExchange(exchangeName);return "交换机已创建: " + exchangeName;}/*** 动态绑定队列和交换机** @param queueName    队列名称* @param exchangeName 交换机名称* @param routingKey   路由键* @return 处理结果*/@GetMapping("/bindQueue")public String bindQueueToExchange(@RequestParam("queueName") String queueName,@RequestParam("exchangeName") String exchangeName,@RequestParam("routingKey") String routingKey) {rabbitDynamicConfigService.bindQueueToExchange(queueName, exchangeName, routingKey);return "队列和交换机已绑定: " + queueName + " -> " + exchangeName;}/*** 动态删除队列** @param queueName 队列名称* @return 处理结果*/@GetMapping("/deleteQueue")public String deleteQueue(@RequestParam("queueName") String queueName) {rabbitDynamicConfigService.deleteQueue(queueName);return "队列已删除: " + queueName;}/*** 动态删除交换机** @param exchangeName 交换机名称* @return 处理结果*/@GetMapping("/deleteExchange")public String deleteExchange(@RequestParam("exchangeName") String exchangeName) {rabbitDynamicConfigService.deleteExchange(exchangeName);return "交换机已删除: " + exchangeName;}// 创建并绑定 Fanout 交换机@GetMapping("/createDirectExchange")public String createDirectExchange(@RequestParam String exchangeName, @RequestParam String queueName, @RequestParam String routingKey) {rabbitDynamicConfigService.createDirectExchange(exchangeName);rabbitDynamicConfigService.bindQueueToDirectExchange(queueName, exchangeName, routingKey);return "Fanout Exchange and Queue Binding created: " + exchangeName + " -> " + queueName + " with routing key: " + routingKey;}// 创建并绑定 Fanout 交换机@GetMapping("/createFanoutExchange")public String createFanoutExchange(@RequestParam String exchangeName, @RequestParam String queueName) {rabbitDynamicConfigService.createFanoutExchange(exchangeName);rabbitDynamicConfigService.bindQueueToFanoutExchange(queueName, exchangeName);return "Fanout Exchange and Queue Binding created: " + exchangeName + " -> " + queueName;}// 创建并绑定 Topic 交换机@GetMapping("/createTopicExchange")public String createTopicExchange(@RequestParam String exchangeName, @RequestParam String queueName, @RequestParam String routingKey) {rabbitDynamicConfigService.createTopicExchange(exchangeName);rabbitDynamicConfigService.bindQueueToTopicExchange(queueName, exchangeName, routingKey);return "Topic Exchange and Queue Binding created: " + exchangeName + " -> " + queueName + " with routing key: " + routingKey;}// 创建并绑定 Headers 交换机@GetMapping("/createHeadersExchange")public String createHeadersExchange(@RequestParam String exchangeName, @RequestParam String queueName, @RequestParam Map<String, String> headersMap) {Map<String, Object> headers = new HashMap<>(headersMap);rabbitDynamicConfigService.createHeadersExchange(exchangeName);rabbitDynamicConfigService.bindQueueToHeadersExchange(queueName, exchangeName, headers);return "Headers Exchange and Queue Binding created: " + exchangeName + " -> " + queueName + " with headers: " + headers;}
}

5、RabbitMQ中的Queue消息监听动态操作接口

RabbitChannelListenerController.java

import com.chain.air.rpp.exchange.rabbit.RabbitDynamicConfigService;
import jakarta.annotation.Resource;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;/*** @className: RabbitListenerController* @program: chain* @description: RabbitMQ 监听器 Controller 组件* @author: kenny* @create: 2024-10-04 01:30* @version: 1.0.0*/
@RestController
@RequestMapping("/rabbit/channel/listener")
public class RabbitChannelListenerController {@Resourceprivate RabbitDynamicConfigService rabbitDynamicConfigService;/*** 创建监听器，监听指定队列** @param queueName 队列名称* @return 处理结果*/@GetMapping("/queue")public String listenQueue(@RequestParam("queueName") String queueName) {rabbitDynamicConfigService.createQueue(queueName, true);return "开始监听队列：" + queueName;}
}
