springboot集成使用rabbitmq笔记(2.rabbitmq使用)

1. 使用rabbitmq笔记一
2. 使用rabbitmq笔记二
3. 使用rabbitmq笔记三

1.引入包

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

            <!-- spring-web相关  -->
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>

            <!-- 工具 -->
            <dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
            </dependency>
        </dependencies>

2.配置

        spring:
          rabbitmq:
            addresses: 192.168.37.134
            port: 5672
            username: admin
            password: admin
        server:
          port: 8035
          context-path: /
        rabbit:
          queueName:
            testQueue1: testqueue1
            testQueue2: testqueue2
            testQueue3: testqueue3
          exchange:
            exchangeName: test_publish_exchange

3.使用代码

3.1.配置类生成使用的bean

            @Configuration
            public class RabbitmqConfig {

                @Value("${rabbit.queueName.testQueue1}")
                private String testQueue1;

                @Value("${rabbit.queueName.testQueue2}")
                private String testQueue2;

                @Value("${rabbit.queueName.testQueue3}")
                private String testQueue3;


                @Value("${rabbit.exchange.exchangeName}")
                private String exchangeName;

                /**========================生产者配置===================*/
                @Bean
                public Exchange testExchange() {
                    return new TopicExchange(exchangeName);
                }

                /**===================消费者配置===================*/
                @Bean
                public Queue getQueue1(){
                    return new Queue(testQueue1);
                }

                @Bean
                public Queue getQueue2(){
                    return new Queue(testQueue2);
                }

                @Bean
                public Queue getQueue3(){
                    return new Queue(testQueue3);
                }

                @Bean
                public Binding testConsumeBinding1() {
                    //消费队列绑定
                    return new Binding(testQueue1, Binding.DestinationType.QUEUE,
                            exchangeName,"*.test1.*", null);
                }

                @Bean
                public Binding testConsumeBinding2() {
                    //消费队列绑定
                    return new Binding(testQueue2, Binding.DestinationType.QUEUE,
                            exchangeName,"*.*.test2", null);
                }
                @Bean
                public Binding testConsumeDlxBinding3() {
                    //消费队列绑定
                    return new Binding(testQueue3, Binding.DestinationType.QUEUE,
                            exchangeName,"test3.#", null);
                }
            }

3.2.发送消息

            @RestController
            @Slf4j
            public class RabbitMQProduceController {

                /** 发送消息注入 AmqpTemplate*/
                @Autowired
                private AmqpTemplate rabbitTemplate;

                @Value("${rabbit.queueName.testQueue1}")
                private String testQueue;

                @RequestMapping(value = "/send")
                public String sendMsg(String msg){
                    send("test.test1.test2",msg+"-send1");
                    log.info("send1发送消息成功,routingKey:test.test1.test2,消息:{}",msg+"-send1");

                    send("test3.test1.test",msg+"-send2");
                    log.info("send2发送消息成功,routingKey:test3.test1.test,消息:{}",msg+"-send2");

                    send("test3.test2.test1",msg+"-send3");
                    log.info("send3发送消息成功,routingKey:test3.test2.test1,消息:{}",msg+"-send3");
                    return "ok";
                }

                private void send(String routingKey,Object content) {
                    rabbitTemplate.convertAndSend("test_publish_exchange",routingKey,content);
                }
            }

3.3.接收消息

            @Component
            @Slf4j
            public class RecieveListener {
                @RabbitListener(queues = "${rabbit.queueName.testQueue1}")
                public void processMsg(Message msg) {
                    log.info("1(*.test1.*).接收rabbitmq的msg : {}", msg.getPayload());
                }
            }
            @Component
            @RabbitListener(queues = "${rabbit.queueName.testQueue2}")
            @Slf4j
            public class RecieveListener2 {
                @RabbitHandler
                public void processMsg(@Payload String msg) {
                    log.info("2(*.*.test2).接收rabbitmq的msg : {}", msg.toString());
                }
            }
            @Component
            @Slf4j
            public class RecieveListener3 {
                @RabbitListener(queues = "${rabbit.queueName.testQueue3}")
                public void processMsg(@Payload String msg) {
                    log.info("3(test3.#).接收rabbitmq的msg : {}", msg);
                }
            }

3.4.启动并访问接口http://localhost:8035/send?msg=message

            INFO 10976 --- [nio-8035-exec-1] c.e.s.produce.RabbitMQProduceController  : send1发送消息成功,routingKey:test.test1.test2,消息:message-send1
